Eight new metal organic frameworks based on the tetrakis(imidazole) ligand tetrakis(imidazol-1-ylmethyl)methane (L), namely, [Zn-2(L)(SO4)(2)]center dot 2H(2)O [Co(L)(SO4)]center dot 1.25H(2)O (2), [Zn-2(L)(L-1)(2)]center dot 3.5H(2)O (3), [Co-2(L)(L-1)(2)]center dot 2.5H(2)O (4), [Zn-2(L)(L-2)(H2L2)(2)]center dot 5H(2)O (5), [Co-1.5(L)(L-2)] (6), [Zn2( L)( L3)] 41120 (7), and [Co(L)(1120)2] (1-12L3) 1.51-120 (8), where H2L(1) =1,4-benzenedicarboxylic acid, H3L2 = 1,3,5-benzenetricarboxylic acid, and H4L3 = 1,2,4,5-benzenetetracarboxylic acid, have been synthesized under hydrothermal conditions. Compounds I and 2 were isolated by the reactions of L with inorganic SO42- anions. Compound I displays a 2-fold interpenetrated PtS net. Compound 2 possesses a binodal (4,6)-connected topology with the Schlafli symbol of (3.4.5(3).6)(3(2).4.5(4).6(7). 7). Compounds 3-8 have been obtained by the reactions of L with organic carboxylate ligands. Compound 3 shows a trinodal (3,4)-connected topology with the Schlalli notation of (6(6))(6(5).8)(6(3)). Compound 4 is isostructural with 3. The compound 5 is a binodal (3,4)-connected two-dimensional (2D) net with the the Schllifli notation 01(62.8) (4. 64. 8). 6 shows a trinodal (3,4)-connected framework with the Schlalli symbol of (4.8(2))(2)(4(2).8(4))(8(4).12(2)). Compound 7 exhibits a pentanodal net with the Schlafli symbol of (4.6.8(4))(4(2).6(4))(4(2).8(4))(4(2).8(3).10)(4.6(2).8(3)). Compound 8 is a rare 4-connected 2D net with the Schlafli symbol of (4(3).6(3)). The influence of the metal atoms and ligands on the structures of the coordination polymers has been discussed. The infrared spectra, thermogravimetric analysis, and luminescent properties were also investigated for the compounds.
