Crystal and Molecular Structure of (CH3)2Sn(C6H5Cr(CO)3)2.
Abstract
Eta 6, eta 6-dimethyldiphenylstannane-bis-tricarbonylchromium, (CH3)2Sn(C6H5Cr(CO)3)2 crystallizes in the orthorhombic space group Pna2 sub 1 with Z = 4, a = 2663(2), b = 1032.0(8), c = 762.7(3) pm, V = 2096 x 1 million pm cu. The crystal structure has been determined by the heavy atom method and refined to final R values of R = 0.005 and R sub w = 0.059 for 1789 independent reflections using Mo-K sub alpha radiation. in the lattice, the molecule is disordered in that one of the Cr(CO3) groups can be on either side of the phenyl ring to which it is bonded; the unit cell contains molecules of both configurations in equal numbers. The geometry of the four groups around the tin atom is approximately tetrahedral; thus, anomalous spectral properties of this compound cannot be attributed to molecular distortion of the normal tin geometry.
