Bis(2,2′-bipyridine-κ2N,N′)(thiocyanato-κN)copper(II) perchlorate

The asymmetric unit of title compound, [Cu(NCS)-(C10H8N2)(2)]ClO4, contains a bis(2,2'-bipyridine)(isothiocyanato)copper(II) cation and a perchlorate anion. In the cation, the Cu2+ ion is coordinated by four N atoms from two bidentate 2,2'-bipyridine molecules and an N atom from an isothiocyanate anion, resulting in a distorted CuN5 pyramidal configuration. The crystal structure is stabilized by weak intermolecular C-H center dot center dot center dot O and C-H center dot center dot center dot S hydrogen bonds, and weak pi-pi interactions between 2,2'-bipyridine rings [centroid-centroid distance = 3.908 (4) angstrom]. The perchlorate counteranion is disordered over two positions in a 0.66:0.34 ratio.
