The new cobalt(II) phosphine oxide complexes Co(Cy 3PO) 2Cl 2 (1), Co(Cy 3PO) 2Br 2 (2), Co(Cy 3PO) 2I 2 (3), Co(Ph 2CyPO) 2Cl 2 (4), Co(Ph 2CyPO) 2Br 2 (5), Co(Ph 2CyPO) 2I 2 (6), Co(Ph 2EtPO) 2Br 2 (7), Co(Cy 3PO) 2(NCS) 2 (8) and Co(Cy 3PO) 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. © 2011 Elsevier Ltd. All rights reserved.
