Employing tetracarboxylate and imidazole mixed ligands to react with different transition meat salts afford two new 3D coordination polymers, {[Zn-2(BPTC)(BBI)(2)]center dot(H2O)(3)center dot DMSO}(n) (1) and {[Cd-2(BPTC)(BBI)(2)]center dot H2O}(n) (2) (H4BPTC = biphenyl-3,3',4,4'-tetracarboxylic acid, BBI = 1,1'-(1,4-butanediyl)bis(imidazole)). Both these two coordination polymers are 4-connected network topologies. Compound 1 features a unprecedented 3-nodal (4,4,4)-connected network topology with the point symbol {6(4)center dot 8(2)}, and 2 displays a (4,4)-connected binodal network bearing new topology with the point symbol of {7(2)center dot 8(4)}2{7(3)center dot 8(3)}. Additionally, thermal stability and photoluminescence properties of 1 and 2 were investigated.
