摘要

Hydrothermal reactions of Mn(II), Co(II), Cu(II), and Cd(II) salts with 2-((1H-1,2,4-triazol-1-yl)methyl)-1H-imidazole-4,5-dicarboxylic acid (H 3tmidc) lead to four novel coordination polymers, namely, [Mn _3(tmidc) _2(H _2O) _4]?(H _2O) 6 (1), [Co _3(tmidc) _2(H _2O) _4]?(H _2O) _4 (2), [Cu _3(tmidc) _2(H _2O)]?(H _2O) (3), and [Cd(Htmidc)] (4). Compound 1 has a three-dimensional (3D) architecture, and the topological study shows that its framework features a 3D (3,4)-connected fsc-3,4-Pbca network with the Schl?fli topological symbol of (6 ~3)(6 ~3.8 ~3). Compound 2 exhibits a 3D pillared framework constructed by 4-fold one-dimensional (1D) helical chains and possesses open helical channels in the framework. Topological analysis reveals that it is a unique (3,4)-connected net with the Schl?fli symbol of (4.5 ~2)(4.5.11 ~4) which is not enumerated in RCSR andTOPOS, and has not been reported in the literature. Compound 3 features a 3D intricate framework displaying a new (3,4)-connected 4-nodal net with the Schl?fli symbol of (5.7 ~2)(4.5.7)(5 ~2.7 ~2.8.10)(4.5.7 ~3.8) which has not been observed in any other coordination polymers. Topological analysis of the 3D network found in compound 4 reveals that the whole structure can be rationalized as a (4.6 ~5)(4.6 ~5) crb topological net.
