The crystallographic data reveal that the ligand bbimc belongs to the triclinic system with space group P-1. The molecule presents a “V” shape (Fig. 1a), the bbimc ligand presents in syn-mode and the two benzimidazole rings distort from the carbazole plane. In addition, as shown in Fig. 1b, the extreme negative electrostatic potentials in the ESP-mapped surface of bbimc were −42.35 and −42.46 kcal/mol, which show strong coordination ability of the active electronegative nitrogen atom.

Two new Zn(II)/Cd(II) luminescent coordination polymers (CPs) based on the V-shaped bis(imidazole) ligand 3,6-bis (1H-benzo[d]imidazol-1-yl)-9-methyl-9H-carbazole (bbimc) with [1,1'-biphenyl]-4,4'-dicarboxylic acid ligand (H(2)bpdc) have been synthesized under solvothermal conditions: {[Zn(bbimc)(bpdc)]·DMF·2.5H(2)O} (CP 1), {[Cd(bbimc)(bpdc)]·2DMF} (CP 2). CP 1 and CP 2 both display a uninodal 4-c unimodal sql topology 2D framework with vertex symbols of {4(4)·6(2)}. In addition, the two identical 2D nets of CP 2 were interpenetrated each ...
