Reactions between triarylphosphanes of type P(C6H4CH2NMe 2-2)xPh3-x [x = 1(1), 2(2), 3 (3)] and CoCl2·6H2O in a 1:1 molar ratio resulted in cobalt(II) complexes of type [CoCl2{P(C6H4CH2NMe2-2) xPh3-x}] [x = 1(4), 2(5), 3 (6)]. The new species were isolated as blue solids and they were investigated by 1H and 31P NMR, mass spectrometry and electronic spectroscopy. X-ray diffraction studies revealed a monomeric structure in case of the starting phosphane P(C6H4CH2NMe2-2)2Ph (2), in which one 2-(Me 2NCH2)C6H4 pendant arm is involved in an intramolecular N→P interaction. The oxidized species [CoCl2{OP(C6H4CH 2NMe2-2)xPh3-x}] [x = 2 (5a), 3 (6a)] were also isolated as blue solids. A similar coordination pattern as in case of the related [ZnCl2{OP(C6H4CH 2NMe2-2)2Ph}] (7) might be proposed for such oxidized species.
