Bis(2-chloro-1,10-phenanthroline-κ2N,N′)(thiocyanato-κN)zinc (2-chloro-1,10-phenanthroline-κ2N,N′)tris(thiocyanato-κN)zincate

Abstract

The asymmetric unit of the title compound, [Zn(NCS)(C12H7ClN2)2][Zn(NCS)3(C12H7ClN2)], contains two cations and two anions. In the cations, the ZnII ions have distorted trigonal–bipyramidal environments formed by four N atoms from two 2-chloro-1,10-phenanthroline (cphen) ligands and one N atom from a thiocyanate ligand. The ZnII atoms in the complex anions also have distorted trigonal–bipyramidal environments, formed by two N atoms from a cphen ligand and three N atoms from three thiocyanato ligands. The crystal packing exhibits π–π interactions between the rings of the cphen ligands [shortest centroid–centroid distance = 3.586 (5) Å] and short intermolecular S...Cl [3.395 (5) Å] and S...S [3.440 (4) Å] contacts.
