Four Cd/Zn coordination frameworks, namely, [Cd(TPBA-4)(NO3)2]·2DMF·1.22H2O (1), [Cd(TPBA-4)(NO3)2]·H2O (2), [Cd(TPBA-4)(NO3)2]·2.2Me2CO·0.32H2O (3), and [Zn(TPBA-4)(NO3)2]·1.5Me2CO (4) were synthesized by the reaction of N′,N″,N‴-tris(pyrid-4-ylmethyl)-1,3,5-benzenetricarboxamide (TPBA-4) with the corresponding d10 metal salts. X-ray diffraction analysis revealed that complex 1 was of two-fold interpenetrated 2D network with interlocked cage-like motif. The structure of 2 is three-fold interpenetrated 2D honeycomb network. On the other hand, the 3 and 4 are isomorphous and isostructural, and have different 2D networks compared to 1 and 2. Thus the series of complexes have the same metal atoms and ligands but different structures. In complex 1, 2, 3, and 4, the flexible TPBA-4 ligands are versatile and adopt different conformations according to different reaction conditions, which predominates the final structures of these complexes. The physical properties of these complexes were also investigated.
