摘要：

Two novel uranyl adipates are reported as synthesized via hydrothermal treatment of uranium oxynitrate and adipic acid. One-dimensional UO2(C6H8O4)(H2O)(2) (1) [a = 9.6306(6) Angstrom, c = 11.8125(10) Angstrom, tetragonal, P4(3)2(1)2 (No. 96), Z = 4] consists of chains Of (UO2)O-4(H2O)(2) hexagonal bipyramids tethered through a linear adipic acid backbone. Three-dimensional UO2(C6H8O4) (2) [a = 5.5835(12) Angstrom, b = 8.791(2) Angstrom, c = 9.2976(17) Angstrom, alpha = 87.769(9)degrees, beta = 78.957(8)degrees, gamma = 81.365(11)degrees, triclinic, P (1) over bar (No. 2), Z = 2] is produced by decreasing the hydration level of the reaction conditions. This structure contains a previously unreported [(UO2)(2)O-8] building unit cross-linked into a neutral metal-organic framework topology with vacant channels.
