摘要

Seven novel coordination polymers derived from the 3-(3',5'-dicarboxylphenoxy)phthalic acid (H4L) ligand have been constructed under similar synthesized conditions with Co(II), Zn(II), Cd(II) ions in the presence of N-donor ancillary ligands, namely, [Co-2(HL)(4,4'-bipy)(mu(3)-OH)(mu(2)-H2O)](n), (1), [Co-2(L)(dpa)(2)](n) (2), {[Co-2(L)(4,4'-bibp)(H2O)(4)]center dot H2O}(n) (3), [Co-2(L)(dib)(2)](n) (4), [Co-2(L)(bix)(1.5)](n) (5), [Zn-2(L)(bix)(1.5)](n) (6), and {[Cd-2(L)(bix)(0.5)(H2O)]center dot 2H(2)O}(n) (7). The various topologies of the structures have been generated by adjusting the N-donor ligands and the central metal ions. Complex 1 displays a tfz-d topology with (3,8) connected structure, and the Schlafli symbol is (4(3))(2)(4(6).6(18).8(4)). Complex 2 shows a 4-connected structure of sod topology with a Schlafli symbol of (4(2).6(4)), forming a three-dimensional (3D) 2-fold interpenetrating structure. Complex 3 presents a novel (3,3,4)-connected topology with a Schlafli symbol of (6(3).8(3))(6(3))(8(3)) and shows 2D -> 3D supramolecular structure through C-H center dot center dot center dot O hydrogen bonds. Complex 4 features a four-connected structure of Nbo topology. Complex 5 and 6 are defined as the same novel (4,4,5)-connected topology with a Schlafli symbol of (4.5.6.8(3))(4(2).5(3).6)(4(3).5(3).6(2).7(2)). In addition, complex 7 can be simplified as a (3,8)-connected tfz-d topology with a Schlafli symbol of (4(3))(2)(4(6).6(18).8(4)). The contrast of 1-5 reveals that the ancillary ligands have key roles in adjusting the crystal structures, and the contrast of 5-7 indicates the central metal ions' influences. Moreover, the magnetic properties of 1-5 and the fluorescence properties of 6 and 7 are discussed.
