Abstract

The structures of H2Ru6(CO)14(L)(C6H4O) (L = CO, (P(OMe3) in solution (as indicated by 1H NMR studies) and in the solid state (as indicated by X-ray studies) are discussed. The two-dimensional COSEY spectrum of the unsubstituted cluster shows the presence of two isomers in solution, whereas in the solid state only one form is present. There is no evidence for more than one isomer for the phosphite-substituted cluster in solution or in the solid state. Long-range 31P-1H couplding differentiates between the 1H NMR signals of the doubly- and triply-bridging hydrides. Reactions of Ru3(CO)12 with para-substituted phenols XC6H4OH (X = NO2, NH2) are also reported.
