Synthesis and Structure of an Iridium(III)-ferrocenyl-dithiophosphonate Complex [{Fc(OCH3)PS2}Ir(cod)] (Fc = Fe(η5-C5H4)(η5-C5H5),cod=1,5 Cyclooctadiene)

The title complex [Fc(OCH3)PS2Ir(cod)] (1, Fc = Fe(eta(5)-C5H4)(eta(5)-C5H5), cod = 1,5-cyclooctadiene) has been prepared ana characterized by X-ray diffraction analysis. It crystallizes in monoclinic, space group P2(1)/n with a = 12.5567(5), b = 13.5197(5), c = 11.7833(4) angstrom, beta = 99.651(2)degrees, V = 1972.06(13) angstrom(3), Z = 4, M-r = 611.52, D-c = 2.06 g/cm(3), mu(MoK alpha) = 7.775 mm(-1), F(000) = 1184, S = 1.063, the final R = 0.0199 and wR = 0.0468 for 4063 observed reflections with I > 2 sigma(I) and 227 variables. The molecular structure of 1 shows that the central iridium atom is chelated by the [Fc(OCH3)PS2](-) ligand via two sulfur atoms and coordinated by one eta(4)-cod molecule via four carbon atoms in a distorted octahedral coordination geometry. The average Ir-S and Ir-C bond lengths are 2.3712(8) and 2.122(3) angstrom, respectively.
