Abstract

The new cobalt(II) phosphine oxide complexes Co(Cy(3)PO)(2)Cl(2) (1), Co(Cy(3)PO)(2)Br(2) (2), Co(Cy(3)PO)(2)I(2) (3), Co(Ph(2)CyPO)(2)Cl(2) (4), Co(Ph(2)CyPO)(2)Br(2) (5), Co(Ph(2)CyPO)(2)I(2) (6), Co(Ph(2)EtPO)(2)Br(2) (7), Co(CY(3)PO)(2)(NCS)(2) (8) and Co(Cy(3)PO)(2)(NO(3))(2) (9) have been prepared mainly by the reaction of anhydrous CoX(2) (X = Cl, Br, I, NCS, NO(3)) with the appropriate phosphine oxide. The complexes were characterised by single-crystal X-ray crystallography supported by IR and UV-Vis absorption spectroscopy. The structural analyses show that the cobalt(II) centre adopts a distorted tetrahedral coordination geometry except for 9 which displays an octahedral geometry. Systematic structural features of these complexes are explained within this paper. (C) 2011 Elsevier Ltd. All rights reserved.
