    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.

    In the title centrosymmetric dinuclear complex, [Cu(2)(C(15)H(11)BrN(2)O(3)S)(2)(C(2)H(6)OS)(2)], the Cu(II) ion is N,O-chelated by a dianionic ligand, monocoordinated by the sulfonamide N atom of a symmetry-related ligand and coordinated by an O atom from a dimethyl sulfoxide ligand, forming a distorted square-planar coordination geometry.

    The two independent mol-ecules in the asymmetric unit of the title compound, C(15)H(16)N(2)O(3)S, are each linked by an N-H⋯O(sulfon-yl) hydrogen bond into a linear chain that runs along the shortest axis of the triclinic unit cell. The hydr-oxy groups are engaged in intra-molecular hydrogen bonding and the amino N atom shows pyramidal coordination.
