catena-Poly[[dipyridylcopper(II)]-di--thiocyanato]

G. Chen, Z.-P. Bai and S.-J. Qu

Abstract: The title complex, [Cu(NCS)₂(C₅H₅N)₂]_n, is a polymeric copper(II) compound. Each Cu^II 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 Cu^II 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 Cu^II atoms lying on a centre of inversion.
