Two new coordination polymers [Pb 3 NaCBPTC) 2 (H 2 O) 2 (Me 2 NH 2 ) (1) and [Zn 2 (BPTC)(H 2 O)××(DMF) 2 ](H 2 O) 3 (DMF) (2) are constructed using different metal salts and 3,3′,5,5′-biphenyltetracarboxylic acid (H 4 BPTC) as building blocks. The resulted coordination polymers are characterized by the elemental analysis and single crystal X-ray diffraction, which reveals that complex 1 features a six-nodal (5,6,6,6,10,12)-connected net with a 3D framework structure, while complex 2 features a trinodal (3,4,7)-connected ttd topological net with a 3D cluster-based network. Furthermore, the in vitro anticancer activity of complexes 1 and 2 are studied via CCK-8 and LDH release assays.
