摘要

A novel 1-dimensional U(VI) phosphonoacetate, UO2(O3PCH2CO2H)(H2O)·2H2O (1), has been synthesized from the room temperature reaction of uranium nitrate and phosphonoacetic acid (H3PPA) in water. The compound crystallizes in a monoclinic space group (P2_1, a = 8.3517(5)A, b = 7.0013(4)A, c = 8.3728(5)A, β = 107.310(1)°, Z = 2) and exhibits bonding to the UO2~(2+) through both phosphonate and carboxylate oxygen atoms of the acid unit. The crystal structure, thermal and fluorescent behaviors, and role of UO_2~(2+) hydrolysis in the context of ambient versus hydrothermal syntheses are discussed.
