文摘

Hydrothermal reactions of aromatic 3,3鈥?5,5鈥?biphenyltetracarboxylic acid (H₄bpt) and the transitional metal cations in the presence of rigid or flexible N-donor ancillary ligands afford nine novel coordination polymers, namely, [M(H₂bpt)(Hpptp)]_n (M = Mn (1), Fe (2), Co (3), and Zn (4)), [Mn₂(bpt)(Hpptp)₂]_n (5), {[Zn₃(Hbpt)(bpt)(H₂O)₂][(4,4鈥?H₂bmib)_0.5]路H₂O}_n (6), {[Cu(bpt)_0.5(4,4鈥?bimbp)]路H₂O}_n (7), {[Co(H₂bpt)(2,7-dfo)]路H₂O}_n (8), and {[Ni₂(bpt)(4,4鈥?bibp)_2.5(H₂O)]路3(H₂O)}_n (9) (Hpptp = 2-(3-(4-(pyridin-4-yl)phenyl)-1H-1,2,4-triazol-5-yl)pyridine; 4,4鈥?bmib = 4,4鈥?bis(2-methylimidazol-1-yl)benzene; 4,4鈥?bimbp = 4,4鈥?bis(imidazol-1-ylmethyl)biphenyl; 2,7-dfo = 2,7-di(imidazo-1-ly)-9H-fluoren-9-one; 4,4鈥?bibp = 4,4鈥?bis(imidazol)biphenyl). Their structures have been determined by single-crystal X-ray diffraction analyses, elemental analyses, IR spectra, powder X-ray diffraction (PXRD), and thermogravimetric (TG) analyses. Complexes 1鈥?b>4 are isomorphism and feature a similar 2-fold interpenetrating 2D helical double layer, which is further extended via the interlayer 蟺路路路蟺 interactions into a 3D supramolecular structure. Complex 5 displays a pillared-layer 3D porous network with a (6².8)₂(6².8².10²) topology. Compound 6 shows an unprecedented 3D host-framework consisting of Zn₆ clusters and exhibits a novel 3D (5,5,5,6,9)-connected topological net with the Schl盲fli symbol of (4¹⁰.6⁵)(4¹⁹.6¹⁶.8)(4⁶.6⁴)(4⁷.6³)₂. The topology of 7 is an unprecedented binodal (4,4)-connected 3D network with the Schl盲fli symbol of (6².8⁴)(4².8²)₂. Complex 8 exhibits a 3D (6⁶) structure with left- and right-handed helical chains arranged alternately. Complex 9 is a novel trinodal (4,4,5)-connected 3D framework with the Schl盲fli symbol of (6⁴.8²)(6⁵.8)(6⁸.8²). To the best of our knowledge, the 3D frameworks with (5,5,5,6,9)-connected net for 6, binodal (4,4)-connected for 7, and trinodal (4,4,5)-connected for 9 have never been documented to date. Moreover, the luminescent properties of 4 and 6 have been investigated.
