THE SOLID-STATE STRUCTURE OF THE CATION -P-O'P'](PENTAMETHYLCYCLOPENTADIENYL)RUTHENIUM(II)

Cationic, monochelated is[(1,3-dioxane-2-ylmethyl)diphenylphosphine-P; O', P'](pentamethyicyclopentadienyl)rutherium (2) was obtained by chlo ride abstraction from CpRuCl(P similar to O)(2) (1) with NaBPh(4). P- 31 CP MAS NMR investigations together with an X-ray crystal structure analysis of 2 were carried out to determine the diastereomeric composi tion of the complex in the solid state. These results are compared wit h the spectroscopic data of 2 in solution. 2 crystallizes in the monoc linic space group P2(1)/c with Z = 4. The cell dimensions are: a = 138 7(2), b = 2235(2), c = 1836(2) pm, beta = 100.8(1)degrees, R(1) = 0.09 3 and wR(2) = 0.229.
