title: Bis(2,2'-bipyridine-κN,N')(thio-cyanato-κN)copper(II) perchlorate.
abstract: The asymmetric unit of title compound, [Cu(NCS)(C(10)H(8)N(2))(2)]ClO(4), contains a bis-(2,2'-bipyridine)(isothio-cyanato)copper(II) cation and a perchlorate anion. In the cation, the Cu(2+) ion is coordinated by four N atoms from two bidentate 2,2'-bipyridine mol-ecules and an N atom from an isothio-cyanate anion, resulting in a distorted CuN(5) pyramidal configuration. The crystal structure is stabilized by weak inter-molecular C-H⋯O and C-H⋯S hydrogen bonds, and weak π-π inter-actions between 2,2'-bipyridine rings [centroid-centroid distance = 3.908 (4) Å]. The perchlorate counteranion is disordered over two positions in a 0.66:0.34 ratio.
