Preparation and crystal structure of the 1,2-dimethoxyethane complex of bis(bis(trimethylsilyl)amido)dichlorouranium(IV)
The complex ((Me/sub 3/Si)/sub 2/N)/sub 2/UCl/sub 2/(1,2-dimethoxyethane) has been prepared from uranium tetrachloride and 2 mol equiv of sodium bis(trimethylsilyl)amide in 1,2-dimethoxyethane. It may also be prepared from uranium tetrachloride and 2 mol equiv of sodium bis(trimethylsilyl)amide in tetrahydrofuran followed by addition of 1,2-dimethyoxyethane. The green pentane-soluble complex crystallizes in space group Pbca with cell dimensions a = 15.207 (4) A, b = 12.021 (3) A, and c = 33.427 (9) A, with Z = 8 and d/sub x/ = 1.57 g cm/sup -3/. The uranium atom, with approximate C/sub 2/ local symmetry, is coordinated to two nitrogen atoms from the amide groups, two oxygen atoms from the dimethoxyethane group, and two chlorine atoms. The average U-N, U-O, and U-Cl distances are 2.23, and 2.59, and 2.64 A, respectively.
