Abstract

V originále

The title compound, K2[Cu2(NCS)2(C12H13NO3)2], consists of two K+ cations and (N-salicylidene-D-valinato)copper(II) and (N-salicylidene-L-valinato)copper(II) coordination units connected through three-atom thiocyanate (-NCS) bridges into a centrosymmetric dianion. The CuII atom adopts a square-pyramidal coordination, with three donor atoms of the tridentate Schiff base and one N atom of the bridging ligand (-NCS) in the basal plane. The axial position is occupied by the thiocyanate S atom of a symmetry-related ligand at an apical distance of 2.9332 (10) Ĺ. Coulombic interactions between six-coordinated K+ ions and the heteroatoms of neighbouring dimeric anions leads to the formation of one-dimensional chains of molecules parallel to [010]. The superposition of the normals of the pyramidal base planes in a direction close to [001] indicates possible pi-pi interactions between neighbouring units.
