A new 3D Ag(I) coordination polymer, [Ag8(btc)2(bpp)2]n(1, H4btc = biphenyl- 2,2ˊ,4,4ˊ-tetracarboxylic acid, bpp = 1,2-bis(4-pyridyl)propane), has been hydrothermally synthesi- zed and characterized by sin... A new 3D Ag(I) coordination polymer, [Ag8(btc)2(bpp)2]n(1, H4btc = biphenyl- 2,2ˊ,4,4ˊ-tetracarboxylic acid, bpp = 1,2-bis(4-pyridyl)propane), has been hydrothermally synthesi- zed and characterized by single-crystal X-ray diffraction analysis, elemental analysis and IR spectroscopy. Complex 1 crystallizes in the triclinic system, space group P1 with a = 13.4899(8), b = 13.4928(8), c = 16.4575(10) , α = 102.7640(10), β = 108.8100(10), γ = 101.4940(10)°, V = 2644.1(3) 3, Z = 2, Dc = 2.401 Mg·m-3, μ = 2.978 mm-1, F(000) = 1840, the final R = 0.0481 and wR = 0.0955 for 6794 observed reflections with I 〉 2σ(I). Complex 1 features a 3D framework formed by Ag(I)-carboxylate chains containing [Ag16(COO)16] secondary building block. Furthermore, thermal stability and electrochemical property of 1 are also investigated in detail. 展开更多

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
