Eight new coordination polymers, namely [Ni(L1)(BIE)] (1), [Cu(L1)(BIE)] (2), [Cu(L2)(BIE)] (3), [Co(L3)(BIE)] (4), [Cu(L4)0.5(BIE)] (5), [Co2(L4)(BIE)2]·H2O (6), [Cu5(L5)4(μ3-O)2(BIE)2(H2O)2] (7) and [Cu3(L6)2(BIE)2(H2O)3] (8), where L1 = p-phthalate, L2 = o-phthalate, L3 = oxalate, L4 = 1,2,4,5-benzenetetracarboxylate, L5 = m-phthalate, L6 = 1,3,5-benzenetricarboxylate and BIE = 2,2′-bis(1H-imidazolyl)ether, were successfully synthesized under hydrothermal conditions. Polymers 1–4 display 2D layer structures. 1, 2 and 3 hold the similar 4-connected 44-sql nets, while 4 exhibits a 3-connected 63-hcb net. 5 possesses an unusual 4-connected Kagomé net with two kinds of connected nodes. 6 shows a rare 3,4-connected (83)2(85·10) topology with 3-connected nodes and square-planar 4-connected nodes. 7 exhibits an α-Po topology based on pentanuclear Cu(II) cluster. 8 is a unique self-penetrating 2D network with 3,4-connected (6·72)(6·7·8)(62·7·82·9) topology. The structural differences of 1–8 suggest the importance of polycarboxylate ligands and central metals in the network construction of the coordination polymers.
