Crystal and molecular structure of an oxo-centered bis((pentamethylcyclopentadienyl)uranium)magnesium phosphoylide complex
The crystal and molecular structure of a novel oxo-centered trimetal cluster of two uraniums and one magnesium has been determined by X-ray diffraction in the hexagonal space groups P6/sub 5/22 (No. 179); cell parameters: a = b = 17.578 (5) A, c = 46.813 (7) A, ..cap alpha.. = ..beta.. = 90/sup 0/, ..gamma.. = 120/sup 0/, V = 12527 (5) A/sup 3/, with R = 0.0634, R/sub w/ = 0.0575, and R/sub G/ = 0.0641. A Cp* is coordinated to each of the two uraniums, and the two are connected by two bridging (CH/sub 2/P(Ph)/sub 2/CH/sub 2/)/sup -/ ligands. Chlorides bridge between each uranium and the magnesium, and the coordination sphere about magnesium is completed by two CH/sub 2/=PMePh/sub 2/ molecules. In addition to the ..mu../sub 3/-oxo ligand, the two uraniums are also bridged by a ..mu../sub 2/-oxide.
