 Abstract    Die Molekül-und Kristallstruktur von Tri-terf-butylcyclotriphosphan-pentacarbonyl-chrom(O), [(f-BuP)3Cr(CO)5] Structural Chemistry of Phosphorus-Containing Chains and Rings, IX [1] The M olecular and Crystal Structure of Tri-/m -butylcydotriphosphane-pentacarbonyl-chrom ium (0), [(r-BuP)3C r(C O)5] The structure of [(f-BuP)3C r(C O)5], C 17CrH2705P3, has been determ ined by single crystal X-ray techniques, solved by 'direct m ethods', and refined to R = 0.048, wR = 0.050 for 3657 reflections by blocked least squares. The com pound crystallizes in the space group P 2x/c with a = 1664.9 pm , b — 916.5 pm , c = 3089.8 pm, ß = 91.45° and Z = 8 formula units. The structure consists of two crystallographically independent but structurally nearly identical m ononuclear [(r-BuP)3C r(C O)5] complexes with the three-m em -bered ring (/-BuP)3 as an unidentate a-donor ligand. Com pared to the free molecule (r-BuP)3 the cyclophosphane ligand is slightly distorted on account of its coordination to the C r(C O)5-group.
