Аннотация

The molecule (h5-pentamethylcyclopentadienyl)(methyldiphenylphosphinite-P)dichlororhodium(III), [(h5-C5Me5)RhCl2(PPh 2OMe)], crystallizes in the monoclinic crystal system in space group P21/c with unit cell parameters a = 16.056(3) Å, b = 9.4331(18) Å, c = 15.745(3) Å, β = 108.330(4)°, V = 2263.8(7) Å3 and Z = 4. There is three-legged piano stool geometry about Rh. The Rh—P distance of 2.278(2) Å is shorter than those of [(h5-C5Me5)RhCl2(PPh2OR)] where R is an aryl group, and longer than those found in [(h5-C5Me5)RhCl2{PPh(OR)2}]. The structure reveals significant distortion of the pentamethylcyclopentadienyl towards 'h3,h2-enyl-ene' coordination.
