Hydrothermal reactions of 3,5-bis(benzimidazol-1-ylmethyl)benzoic acid (HL) with Cd(II), Cu(II) and Zn (II) salts provide eight new metal complexes which were characterized by single crystal and powder Xray diffraction, IR, elemental and thermogravimetric analyses. Two cadmium frameworks [Cd(L)(2)] center dot 2H(2)O (1) and [Cd(L)CI] (2) have 3D structures with (4(2).6(5).8(3))(4(2).6) and rtl (4.6(2)) (2)(4(2).6(10):8(3),) of topologies, respectively. Structural diversity of four copper complexes [Cu-3(L)(2)] center dot NO3 center dot 0.5H(2)O (3), [Cu-2(HL)(2)(SO4)] center dot 3.5H(2)O (4), [Cu(L)(bdc)(0.5)] center dot 1.5H(2)O (5) and [Cu-2(L)(HL)(Hbdc)] (6) (H(2)bdc=1,4-benzenedicarboxylic acid) is achieved through the alteration of copper salts and addition of auxiliary ligand. As a result, 3 has a 1D ladder structure, 4 is a discrete dinuclear complex, 5 displays a (3,4)-connected 2-nodal 3-fold interpenetrating framework with (4(2).6.10(2).12)(4(2).6) topology, 6 exhibits a 4-connected uninodal 2D sql (4(4).6(2)) network. Within the zinc series, ZnCl2 and ZnSO4 were used for the syntheses of [Zn(L)Cl] (7) and [Zn(L)(SO4)(0.5)]center dot 2H(2)O (8), respectively. 7 shows a 3-connected uninodal 2D hcb network with (6(3)) topology and 8 is a (3,6)-connected 2-nodal 3D framework with (4(2).6)(2)(4(4).6(2).8(8).10) topology. The luminescent properties of the Cd(II) and Zn(II) complexes were investigated.
