✦ Synopsis

The coordination geometry of the Co II atom in the title complex, [Co(NCS) 2 (C 16 H 14 N 4 )] or [Co(NCS) 2 (dbz)], where dbz is bis(benzimidazol-2-yl)ethane, is distorted tetrahedral; the Co II atom is coordinated by two N atoms from one dbz molecule and two N atoms from two monodentate NCS À anions.

The title complex, [Co(NCS) 2 (C 8 H 8 N 2 O) 2 ], possesses crystallographically imposed twofold symmetry. The Co II atom is coordinated by four N atoms and two O atoms in a distorted octahedral geometry. The crystal packing is stabilized by weak intermolecular O-HÁ Á ÁS and N-HÁ Á ÁS hydrogen bond
