Structure of three selected dirhodium(II) and cobalt(II) phosphane complexes

The crystal structure of the following complexes has been determined using a KM4CCD Kuma Diffraction Diffractometer with CDD camera, and the original KM4CCD data collection and KM4RED data reduction programs: tetrachlorobis{m-phenylbis(2-pyridyl)phosphane(P,N,N')dirhodium(II), [Rh2Cl4{PPh(C5H4N)2}2], (1); tris(m-acetato-kO: -kO')(acetic acid-1-kO)-m-2-{[(2-methoxyphenyl-2kO)(2-methoxyphenyl)phosphano-2-kP]phenolato-1kO}-dirhodium(II), [Rh2(OOCCH3)3{P(C6H4OCH3)2C6H4O}HOOCCH3], (II); dichlorobis{phenylbis(2-pyridyl)phosphane oxide}cobalt(II), [CoCl2{OP(C5H4N)2}2(C6H5)}2], (III).
