摘要：

The new osmium cluster complex Os7H2(CO)(21)P(OMe)(3), in which P(OMe)(3) is trimethylphosphite, has been synthesized and characterized by X-ray crystallographic analysis. This complex was prepared by the addition of P(OMe)(3) to Os7H2(CO)(21). Crystals are monoclinic, space group P2(1)/c, with a=14.220(3), b=12.071(3), c=24.019(7) Angstrom, beta=109.63(2)degrees and Z=4. The metal atom arrangement consists of a trigonal bipyramid sharing an equatorial vertex with a triangle. The phosphite ligand is bound to one of the outer vertices of the triangular unit. The physical and chemical behavior of this complex is compared with that of two previously reported clusters alleged to be isomers of Os7H2(CO)(22).
