Über Reaktionen von Pyrrolidinium-bis(diethylphosphoryl)phosphinidin mit Chromcarbonylkomplexen / Reaction of Pyrrohdinium-bis(diethylphosphoryl)phosphinidine with Chromiumcarbonyl Complexes

The reaction of [H 2 NC 4 H 8 ]P[P(O)(OC 2 H 5 ) 2 ] 2 with Cr(CO) 5 THF and Cr(CO) 4 C 7 H 8 results in the formation of the 1:1 and 1:2 chromium pentacarbonyl complexes. The 1: 1 complex was characterized on the basis of an X-ray analysis. It crvstallizes in the space group P 1̄ with a = 1091.9(10), 6=1164.1(12), c =1356.4(9) pm, a = 108.89(6), β = 97.57(7), y = 116.24(6), and Z - 2. The average P-P bond length was found to be 215.8 pm
