[1,3-Bis(diphenyl­phosphino)propane]tetra­carbonyl­chromium(0)

In the title mol­ecule, [Cr(C₂₇H₂₆P₂)(CO)₄], the Cr atom is octa­hedrally coordinated by the four carbonyl ligands and a bidentate phosphine ligand, which is bonded as a chelate in a cis position. The average Cr-P and Cr-C bond lengths are 2.3770 (5) and 1.865 (2) Å, respectively.

Special details

Experimental. IR (cyclohexane) υ(CO) 1886 (s), 1916 (s), 2005 (s) cm^-1.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
