| 英文摘要 | Six hybrid uranyl-transition metal compounds [UO2Ni(cptpy)(2)(HCOO)(2)(DMF)(H2O)] (1), [UO2Ni(cptpy)(2)(BTPA)(2)] (2), [UO2Fe(cptpy)(2)(HCOO)(2)(DMF)(H2O)] (3), [UO2Fe(cptpy)(2)(BTPA)(2)] (4), [UO2Co(cptpy)(2)(HCOO)(2)(DMF)(H2O)] (5), and [UO2Co(cptpy)(2)(BTPA)(2)] (6), based on bifunctional ligand 4 '-(4-carboxyphenyl)-2,2 ':6 ',2 ''-terpyridine (Hcptpy) are reported (H(2)BTPA = 4,4 '-biphenyldicarboxylic acid). Single-crystal XRD revealed that all six compounds feature similar metalloligands, which consist of two cptpy(-) anions and one transition metal cation. The metalloligand M(cptpy)(2) can be considered to be an extended linear dicarboxylic ligand with length of 22.12 angstrom. Compounds 1, 3, and 5 are isomers, and all of them feature 1D chain structures. The adjacent 1D chains are connected together by hydrogen bonds and pi-pi interactions to form a 3D porous structure, which is filled with solvent molecules and can be exchanged with I-2. Compounds 2, 4, and 6 are also isomers, and all of them feature 2D honeycomb (6,3) networks with hexagonal units of dimensions 41.91x26.89 angstrom, which are the largest among uranyl compounds with honeycomb networks. The large aperture allows two sets of equivalent networks to be entangled together to result in a 2D+2D -> 3D polycatenated framework. Remarkably, these uranyl compounds exhibit high catalytic activity for cycloaddition of carbon dioxide. Moreover, the geometric and electronic structures of compounds 1 and 2 are systematically discussed on the basis of DFT calculations. |
