2-Amino-cyclo-hexan-1-aminium thio-cyanate

The title compound, C(6)H(15)N(2) (+)·NCS(-), was obtained unexpectedly from the reaction mixture of benzoyl chloride, ammonium thio-cyanate and cyclo-hexane-1,2-diamine. The cyclo-hexane ring adopts a chair conformation. In the crystal, N-H⋯S and N-H⋯N inter-actions involving the thio-cyanate anion and both the amine and the aminium N atoms link the mol-ecules, forming two-dimensional networks parallel to (001).
