摘要：

Uranium tetraiodide, prepared by a high temperature method, reacts with two equivalents of KHBpz(3) in CH2Cl2 giving the orange compound [UI2(HBpz(3))(2)] (1) in 62% yield. The same reaction in THF provides the compound [UI{O(CH2)(4)I}(HBpz(3))(2)] (2) in 66% isolated yield and arising from ring opening of THF by the uranium tetraiodide. The solid state structure of compound 2 has been determined by X-ray crystallography. Compound 1 reacts with NaOC2H5 in the molar ratio 1:1 giving the monoalkoxide [UI(OC2H5)(HBpz(3))(2)] (3), which crystallizes in the monoclinic space group P2(1)/n. X-ray crystallographic analysis shows that in complexes 2 and 3 the uranium is 8-coordinate with the two tridentate HBpz(3) ligands, iodide, and alkoxide displaying square antiprismatic geometry. The solid state structure of the analogous monomeric compound [UCl(OC2H5)-(HBpz(3))(2)] (4) is also described and compared with those of compounds 2 and 3.
