摘要:
Two new uranyl arsonates, Zn(UO2)(PhAsO3)(2)L center dot H2O [L = 1,10-phenanthroline (1) and 2,2'-bipyridine (2)], have been synthesized by hydrothermal reactions of phenylarsonic acid, L, and ZnUO2(OAc)(4)center dot 7H(2)O. Single-crystal X-ray analyses demonstrate that these two compounds are isostructural and exhibit one-dimensional chains in which U-VI and Zn-II cations are directly connected by the yl oxygen atoms and additionally bridged by arsonate groups. Both compounds represent the first examples of uranyl arsonates with heterometallic cation-cation interactions.
