摘要：

Two new uranyl-organic compounds [(UO2)(3)O(OH)(3)(NA)(2)](-) (.) H3O+ (1) (HNA = nicotinic acid) and (UO2)(2)(phen)(2)(BTEC) (2) (H4BTEC = 1,2.4,5-benzenetetracarboxylic acid, phen = 1, 10-phenanthroline) have been prepared under hydrothermal conditions. X-ray single-crystal structure analyses reveal that compound 1 consists of infinite helical polyoxouranium ribbons built up from trinuclear [(UO2)(3)O(OH)(3)](+) units and NA ligands, whereas compound 2 is composed of two-dimensional sheets joined together through pi-pi interactions. Both compounds show intense emission under excitation of UV light. (c) 2005 Elsevier Ltd. All rights reserved.
