Catena-Poly[[dipyridylcopper(II)]-di-μ-thiocyanato

Abstract

The title complex, [Cu(NCS)2(C5H5N)2]n, is a polymeric copper(II) compound. Each CuII atom of the complex has a primary coordination by four N atoms from two pyridyl and two thio­cyanate ligands in mutually trans orientations, which define the equatorial plane. Two weakly coordinated S atoms from the thio­cyanate ligands of adjacent complexes occupy axial positions, giving each CuII atom an axially distorted octa­hedral geometry and forming one-dimensional polymeric chains along the c axis. There are three mol­ecules in the triclinic unit cell with one of the CuII atoms lying on a centre of inversion.
