The self-assembly reactions of the flexible ligand 1,4-bis(1,2,4-triazol-1-yl)butane (btb) and rigid ligand 1,4-benzenedicarboxylate (bdc) with Zn(II) or Cd(II) give two novel coordination polymers {[Zn(bdc)(btb)](H2O)(5)}(n) (1) and {[Cd-2(bdc)(2)(btb)(H2O)(2)](H2O)(7)}(n) (2). Coordination polymer 1, a supramolecular isomer of [Zn-2(bdc)(2)(btb)(2)](H2O)(2) [X.L. Wang, C. Qin, E.B. Wang, Z.M. Su, Chem. Eur. J. 12 (2006) 2680], is a special 2D (6,3) network, with six Zn(II) atoms at six corners and four bc1c and two double btb at six edges. Coordination polymer 2 exhibits a distorted 3D cubic topology that is built from dimer Cd-2 units. The blue luminescent emission maxima at 420 and 439 nm for 1, 440 and 455 nm for 2 were observed in the solid state at room temperature. (C) 2008 Elsevier B.V. All rights reserved.
