摘要
Unusual coordination modes of 1,2-cyclohexane dionedioxime in uranyl complexes, i.e., tridentate chelating/bridging and (E, Z)-pentadentate chelating/bridging ones, were established by X-ray crystallography of single crystals of (CN(3)H(6))(3)[(UO(2))(2)(C(6)H(9)N(2)O(2))(C(6)H(8)N(2)O(2))(C(2)O(4))(2)] center dot (2)H(2)O and [(UO(2))(2)(C(6)H(8)N(2)O(2))(2)(H(2)O)(3)] center dot (2)H(2)O. The conditions of the emergence of such coordination modes were determined. The possibility of (E/Z) izomerization of alpha-dioximes in reactions of uranyl complexes.
