The complex [(Me3Si)2N]2UCl2(1,2-dimethoxyethane) has been prepared for this study from uranium tetrachloride and two molar equivalents of sodium bis(trimethylsilyl)amide in 1,2-dimethoxyethane. It may also be prepared from uranium tetrachloride and two molar equivalents 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) Å, b= 12.021(3) Å, and c = 33.429(9) Å, Z = 8, and dx = 1.57 g cm-3. The uranium atom, which has approximate C2 symmetry, is coordinated to two nitrogen atoms from the amide groups, two oxygen atoms from the dimethoxyethane group, and two chlorine atoms. Lastly, the average U-N, U-O, and U-Cl distances are 2.23, 2.59, and 2.64 Å, respectively.
