The five-coordinate Sn atom in the title mixed organyl stannate compound, (C(12)H(24)N)[Sn(C(5)H(9))(C(6)H(5))(2)(C(2)ClF(2)O(2))], is in a trans-C(3)SnO(2) trigonal-bipyramidal coordination environment. The NH(2) groups of the cations act as hydrogen-bond donors to two symmetry-related anions, resulting in the formation of linear chains. One of the phenyl rings is disordered over two sites with equal occupancies.
In the title salt, [Ag(C(27)H(26)P(2))(2)][Sn(C(6)H(5))(3)(C(2)ClF(2)O(2))], the Ag(I) atom exists in a tetra-hedral coordination geometry formed by four P atoms [Ag-P = 2.460 (1)-2.501 (1) Å], whereas the Sn(IV) atom exists in a trans-trigonal-bipyramidal coordination geometry formed by two O [Sn-O = 2.208 (3) and 2.233 (3) Å] and three C atoms [Sn-C = 2.115 (4)-2.128 (4) Å;(Σ C-Sn-C)= 360.0 (6)°].
The chloride and chloro-difluoro-acetate anions occupy cis positions in the octa-hedral coordination geometry of the title compound, [Mn(C(2)ClF(2)O(2))Cl(C(12)H(8)N(2))(2)]. The two N-heterocycles both chelate the metal atom.
The asymmetric unit of the title compound, [Ag(2)(C(2)ClF(2)O(2))(2)(C(25)H(22)P(2))(2)], consists of two half-mol-ecules, each Ag(I) ion lying on a center of symmetry. In each complete mol-ecule, two bis-(diphenyl-phosphino)methane ligands bridge two Ag(I) ions, which are further coordinated by one chloro-difluoro-acetate ligand, giving T-shaped geometries and short intra-molecular Ag⋯Ag distances of 3.1078 (6) and 2.9950 (6) Å. In one mol-ecule, the unique -CF(2)Cl group is rotationally disordered over two sites with approximate occupancies of 0.53 and 0.47 for the major and minor components, respectively.
In the mononuclear complex mol-ecule of the title compond, [ZnCl(2)(C(18)H(18)N(2)O)(2)]·2C(18)H(18)N(2)O, the Zn atom, which lies on a twofold rotation axis, is coordinated by phenolate O atoms in a tetra-hedral coordination geometry. The coordinated Schiff base uses its indole NH donor site to form a hydrogen bond to the negatively charged phenolate O atom of the uncoordinated zwitterionic Schiff base. There is an intra-molecular N-H⋯O hydrogen bond in the coordinated and uncoordinated Schiff bases. The indole NH site of the uncoordinated Schiff base does not engage in a hydrogen-bond inter-action. The CH(2)-CH(2) group in the uncoordinated Schiff base is disordered equally over two positions.
The anion in the title salt, (C(7)H(11)N(2))[SnBr(2)(C(6)H(5))(3)], lies on a twofold rotation axis that passes through the metal atom as well as the C(ipso)-C(para) atoms of one of the aromatic rings. The metal center is five-coordinate in a trans-Br(2)SnC(3) trigonal bipyramidal geometry. The cation is disordered about a center of inversion.
The Sn atom in the title compound, [Sn(C(5)H(9))(C(6)H(5))(2)(C(6)H(10)N(3)O(2)S)], exists within a tetra-hedral geometry. The -NH(2) group forms a weak hydrogen bond across a center of inversion to the S atom of an adjacent mol-ecule, as well as another weaker hydrogen (across another center of inversion) to the Sn-bound O atom of another mol-ecule. The hydrogen-bonded layer structure is consolidated by a strong hydrogen bond between the -NH- group and the uncoordinated O atom of a third mol-ecule.
The title polymeric mixed-organyl tin hydroxide, [Sn(C(6)H(5))(2)(C(6)H(11))(OH)](n), hass a hydroxide-bridged chain structure; the tin center shows trans-C(3)SnO(2) trigonal bipyramidal coordination. The Sn atom lies on a special position of site symmetry m; the symmetry element relates one phenyl ring to the other and also relates one half of the cyclo-hexyl ring to the other half.
In the title mixed-organyl stannate, (C(12)H(24)N)[Sn(C(6)H(5))(2)(C(6)H(11))(CClF(2)O(2))(2)], there are two cations and two anions in the asymmetric unit. Each five-coordinate Sn atom shows trans-C(3)SnO(2) trigonal bipyramidal coordination. The four Sn-O distances are approximately equal in the two independent anions. Each ammonium cation serves as a hydrogen-bond donor to two stannates, the hydrogen-bonding inter-actions giving rise to linear hydrogen-bonded chains.
In the crystal structure of the title compound, [Fe(C(6)H(4)NO(2))(2)](n), one nicotinate group O,O'-chelates one Fe atom and binds through the N atom to the other Fe atom; the second nicotinate group bridges three Fe atoms through the N and two O atoms. The μ(2)- and μ(3)-bridging modes of the two nicotinate groups result in a polymeric three-dimensional network structure. The Fe atom shows octa-hedral coordination geometry but one of the Fe-O bonds is somewhat long [2.522 (2) Å].
The cation of the title compound, C(7)H(13)ClN(+)·Cl(-), forms a linear hydrogen bond to the chloride anion. The cation is disordered about a mirror plane.
The indolyl -NH group of the title Schiff base, C(19)H(19)N(3)O(2), forms a hydrogen bond to the -OH group of an inversion-related mol-ecule, resulting in a hydrogen-bonded dimer; adjacent dimers are further linked through an inter-dimer N-H⋯O hydrogen bond involving the -C(=O)-NH-N=fragment to form a linear ribbon that runs along the a axis.
The title Schiff base, C(17)H(15)N(3)O(3), exists in the zwitterionic form with the phenol H atom transferred to the imine group. Adjacent zwitterions are linked into a linear chain running along the a axis by an indole-hydr-oxy N-H⋯O hydrogen bond [3.100 (2) Å].
The low-temperature structure of the title compound, C(4)H(8)N(2)O, is ordered, whereas the central methyl-ene groups is disordered in the reported room-temperature structure. The molecule lies across a mirror plane; adjacent mol-ecules are linked by an N-H⋯O hydrogen bond into a chain.
The hydroxyl group in each of the two independent mol-ecules of the title compound, C(7)H(5)NO(4), participates in two O-H⋯O hydrogen bonds, viz. one intra-molecular bond to the nitro group and one inter-molecular bond to the aldehyde group of the same mol-ecule in the next unit, resulting in a linear chain structure. The dihedral angle between the aromatic ring and the nitro group is 10.9 (3)° in one mol-ecule and 9.9 (2)° in the other.
The title compound, C(8)H(7)FO(2), crystallizes as discrete mol-ecules, the conformation of which may be influenced by an intra-molecular hydr-oxy-carbonyl O-H⋯O hydrogen bond.
3,5-dichloro-2-hydroxy-benzaldehyde), C(7)H(4)Cl(2)O(2), crystallizes as discrete mol-ecules, the conformation of which may be influenced by an intra-molecular hydr-oxy-carbonyl O-H⋯O hydrogen bond.
In the essentially planar title mol-ecule, C(10)H(9)BrN(4)S, the C=N double bond is in a trans configuration. In the crystal structure, the S atom acts as a hydrogen-bond acceptor for the aromatic NH, aliphatic NH and terminal NH(2) groups of three symmetry-related mol-ecules, forming a weak hydrogen-bonded layer structure.
The mol-ecules of the title compound, C(10)H(10)N(4)S, are linked by N-H(indole)⋯S hydrogen bonds to form a linear hydrogen-bonded chain. There are two independent mol-ecules in the asymmetric unit.
The mol-ecule of the title compound, C(14)H(10)FN(3)O(3)S, consists of an indole unit and a phenylsulfonyl unit that are disposed in an approximately trans orientation relative to the N-N single bond. Two mol-ecules are arranged about a center of inversion, forming a hydrazide-carbonyl N-H⋯O hydrogen-bonded dimer; the dimers are linked by an indole-sulfonyl N-H⋯O hydrogen bond into a ribbon.
