Acta Crystallogr E Crystallogr Commun. 2016 Jun 10;72(Pt 7):922-5. doi: 10.1107/S2056989016008963. eCollection 2016 Jul 1.

Abstract

The asymmetric unit of the title complex, [Zn(SCN)2(C6H6N2O)2], consists of one Zn(2+) cation located on a twofold rotation axis, as well as of one thio-cyanate anion and one neutral isonicotinamide ligand, both occupying general positions. The Zn(2+) cation is tetra-hedrally coordinated into a discrete complex by the N atoms of two symmetry-related thio-cyanate anions and by the pyridine N atoms of two isonicotinamide ligands. The complexes are linked by inter-molecular C-H⋯O and N-H⋯O, and weak inter-molecular N-H⋯S hydrogen-bonding inter-actions into a three-dimensional network.

Keywords: crystal structure; discrete complex; hydrogen bonding; isonicotinamide; zinc thio­cyanate.
