Abstract
The reaction of UCl4 with KO-2,6-Cl2C6H3 in tetrahydrofuran results in the preparation of the title compound. The six-coordinate complex possesses pse udo-octahedral geometry about uranium, with U-O(phenoxide) bond lengths in the range 2.161(11) to 2.178(10) Angstrom and U-O(THF) bond lengths of 2.46 7(10) and 2.475(11) Angstrom. This complex crystallizes in the monoclinic s pace group, P2(1)/n (a = 11.169(2), b = 11.588(2), c = 35.119(5) Angstrom, beta = 92.11(1)degrees, V = 4542.2(13) Angstrom(3), and Z = 4).
