Multi-topic bridging ligands with two or more nitrogens, sulfur, phosphorus, and/or oxygen-involving functional groups can show different binding abilities to metal ions and thus can be applied as effective tectons for constructing diverse coordination networks [1]. The aromatic polycarboxylate ligands can serve as excellent candidates for building highly connected, self-penetrating, or helical coordination frameworks due to their bent backbones and versatile bridging fashions [2]. Herein we report our successful attempt to combine the 1,2-benzenedicarboxylic acid (1,2-bdcH2) with bipyridine ligands such as 1,2-bis(4-pyridyl) ethane (bpe) and 1,3-bis(4-pyridyl) propane (bpp). Thus, one 2D and two 3D mixed-ligand coordination polymers were obtained: Zn(II)/Cd(II) + 1,2-bdcH2 + bpe bpp {[Zn(1,2-bdc)(bpe)]0.25(dmf)0.25(H2O)}n 1 3D [Cd(1,2-bdc)(H2O)]n [3] 2D [Zn(1,2-bdc)(bpp)]n 2 3D [Cd(1,2-bdc)(bpp)(H2O)]n 3 2D Compounds 1 and 3 crystallize in the centrosymmetric space groups: orthorhombic Cmcm (No 63) (1) and monoclinic P21/n (No 14) (3), while compound 2 crystallizes in hexagonal non centrosymmetric P61 (No 169) space group. In complexes 1 and 2 the metal coordination cores represent tetrahedral N2O2 environment created by two bipyridine molecules and two fully deprotonated-bridging 1,2-bdc anions. Each Cd(II) N2O5-coordination core represents the pentagonal bipyramid that comprises two bidentate-bridging 1,2-bdc anions, two bpp ligands and one water molecule. The solides 1 and 2 demonstrate high cumulative solvent uptake indicated by the 1266.9 Å3 of the free volume (or 27.7% of total volume cell) for 1 after the guest molecules evacuation and 780.3 Å3 (or 12.3%) for 2.
