Hydrothermal reactions of three aromatic polycarboxylic acids and the transitional metal cations in the presence of phen and 1,4-bib afford three new coordination polymers: [Cd2(bpp)1.5(Hbpp)(phen)2]n (1), [... Hydrothermal reactions of three aromatic polycarboxylic acids and the transitional metal cations in the presence of phen and 1,4-bib afford three new coordination polymers: [Cd2(bpp)1.5(Hbpp)(phen)2]n (1), [Mn3(Htptc)2(phen)2(H2O)2]n (2), and {[Cu(btc)0.5(1,4- bib)]·2H2O}n(3) (H2bpp = 2,6-bis(4'-carboxyphenyl)-4-phenylpyridine, H4tptc = terphenyl-2,5,2',5'-tetracar- boxylic acid, H4btc =biphenyl-2,2',4,4'-tetracarboxylic acid, phen =1,10-phenanthroline, and 1,4-bib = 1,4-bis(1H-imidazol-1-yl)benzene). Their structures have been determined by single- crystal X-ray diffraction analyses, elemental analyses, IR spectra, and powder X-ray diffraction (PXRD) analyses. In compound 1, the CdII cations are linked by bpp2- to form one ladder structure, based on which a 3D network is constructed with the help of non-covalent interactions. The topology of 2 is a 3D (3,4,5)-connected framework with the Point Schl?fli symbol of (42.6)2(43.62.8)(45.64.8)2. Compound 3 shows an unprecedented 3D (4,4)-connected framework with the Point Schl?fli symbol of (64.82)2(65.8). Moreover, the luminescent property of 1 has been investigated. 展开更多
