Reaction of cis-[Mo2(MeCO2)2(MeCN)6][BF 4]2 with dmpe and S,S-dppb: Preparation, crystal structure, and spectroscopic properties of trans-[Mo2(MeCO2)2(dmpe)2][BF 4]2 (dmpe = bis(dimethylphosphino)ethane, S,S-dppb = (2S,3S)-bis(diphenylphosphino)butane)

cis-[Mo2(MeCO2)2(MeCN) 6][BF4]2 reacts with dmpe in acetonitrile solution to give orange, air-stable [Mo2(MeCO2)2-(dmpe)2] [BF4]2·MeCN (1), which has been characterized by X-ray crystallography. The complex crystallizes in the space group P21/n with unit cell dimensions a = 16.047 (8) A?, b = 11.582 (4) A?, c = 19.067 (4) A?, β = 101.03 (3)°, V = 3478 A?3, and Z = 4. There are two independent molecules (1a and 1b) of the cation in the unit cell. Both 1a and 1b have a trans ligand arrangement in which the MoPCCPMo rings adopt the novel half-chair conformation analogous to that of cyclohexene. Reaction of the chiral ligand S,S-dppb affords a product formulated as [Mo2(MeCO2)2(S,S-dppb)(MeCN)2] 2+. The CD spectrum of this complex shows that the diphosphine is coordinated to the Mo2 unit in solution.
