The solid state structure of the cation bis[1,3-dioxane-2-ylmethyl) diphenylphosphine- P; O′, P′]-(pentamethylcyclopentadienyl) ruthenium(II)

Abstract

Cationic, monochelated bis[(1,3-dioxane-2-ylmethyl)diphenylphosphine- P; O′, P′](pentamethylcyclopentadienyl)ruthenium(II) ( 2) was obtained by chloride abstraction from Cp ∗RuCl(P ∼ O) 2 ( 1) with NaBPh 4. 31P CP MAS NMR investigations together with an X-ray crystal structure analysis of 2 were carried out to determine the diastereomeric composition of the complex in the solid state. These results are compared with the spectroscopic data of 2 in solution. 2 crystallizes in the monoclinic space group P2 1/ c with Z = 4. The cell dimensions are: a = 1387(2), b = 2235(2), c = 1836(2) pm, β = 100.8(1)°, R 1 = 0.093 and wR 2 = 0.229.
