N2 - Based on a V-shaped bisimidazole ligand and various dicarboxylic acids, nine entangled coordination polymers, namely, [Zn(o-bdc)(bips)]·2H2O (1), [Zn2(cdc)2(bips)2]·2H2O (2), [Zn2(bpedc)2(bips)2] (3), [Zn(odc)(bips)]·H2O (4), [Zn2(sdc)2(bips)2]·5H2O (5), [Co2(sdc)2(bips)2(H2O)]·2H2O (6), [Cd2(bpdc)2(bips)2]·3H2O (7), [Cd2(2,6-ndc)2(bips)2(H2O)2]·2H2O (8) and [Cd(1,4-ndc)(bips)]·DMF·H2O (9) (bips = bis(4-imidazol-ylphenyl)sulfone, o-H2bdc = o-phenyldicarboxylic acid, H2cdc = 1,4-cyclohexanedicarboxylic acid, H2bpedc = 4,4′-stibenedicarboxylic acid, H2odc = 4,4′-oxybisbenzoic acid, H2sdc = 4,4′-sulfonyldibenzoic acid, H2bpdc = biphenyl-4,4′-dicarboxylic acid, 1,4-H2ndc = naphthalene-1,4-dicarboxylic acid, 2,6-H2ndc = naphthalene-1,4-dicarboxylic acid), have been synthesized and structurally characterized. Compound 1 exhibits a 2D → 2D polycatenane of 3-fold interpenetrated sql layers. Compound 2 shows a 2D → 3D polycatenane of 3-fold interpenetrated sql layers. Compound 3 displays a 2D → 3D polycatenane of 5-fold interpenetrated sql layers. Compound 4 exhibits a 2-fold interpenetration of CdSO4 networks. Compound 5 presents a 2D → 3D polycatenane by three-fold interpenetrated {42·63·8}2 layers. Compound 6 features an unusual 2D → 2D polycatenane framework assembled by the entanglement of sql layers containing 2-membered loops. Compound 7 exhibits a 1D → 3D polycatenane by the 3-fold interpenetration of 3-connected ribbons. Compound 8 displays a 3-fold interpenetration of SrAl2 networks. Compound 9 exhibits a 4-fold interpenetration of dia networks in a [2 + 2] mode. Their luminescence properties were also measured.
