| Abstract: | Reactions of the clusters Os3(μ-H)2(μ3-1-OC10H6)(CO)9, 1, and Os3(μ-H)(μ-2-OC10H7)(CO)10, 2, with the group 15 ligands EPh3 (E=P, As, Sb) generally afforded the mono- and, or disubstituted derivatives. These derivatives tend to decompose during chromatographic separations on silica gel; thus one of the decomposition products from the reaction of 1 with PPh3 has been identified as Os(H)2(CO)2(PPh3)2, 3. The molecular structures of 3, as well as the derivatives Os3(μ-H)2(μ3-1-OC10H6)(CO)8(AsPh3), 4, Os3(μ-H)2(μ3-1-OC10H6)(CO)7(SbPh3)2, 5c, Os3(μ-H)(μ-2-OC10H7)(CO)8(AsPh3)2, 7b, and Os3(μ-H)(μ-2-OC10H7)(CO)8(SbPh3)2, 7c, have been determined by single crystal X-ray diffraction studies. |
