•Two entangled coordination polymers were synthesized.•An unusual 6-connected self-catenated three-dimensional network•A 3-fold interpenetrating three-dimensional pcu network•The luminescence and thermal stability were investigated.•The bib ligands show different conformations in 1 and 2.
Two entangled coordination polymers [Cd2(bib)(bdc)2]n (1) and [Cd2(bib)(bda)2]n (2) were synthesized by the hydrothermal reaction (bib = 1,4-bis(2-methyl-imidazol-1-yl)butane, bdc = 1,2-benzenedicarboxylate, bda = 1,4-benzenediacetate). 1 exhibits an unusual 6-connected self-catenated 3D network based on Cd2(COO)2 dimer with the point symbol of (44·610·8). 2 exhibits a 3-fold interpenetrating 3D pcu network based on Cd2(COO)2 dimer. The different conformations of bib ligands (the anti–anti–anti conformation in 1 and gauche–anti–gauche conformation in 2) play the key role in the construction of different structures in 1 and 2. The luminescence and thermal stability were investigated.
