Abstract

A new coordination polymer, [Co2(L)2(4,4′-bipy)]n·3nH2O (1) based on 5-(3-methyl-5-phenyl-4H-1,2,4-triazol-4-yl)isophthalic acid (H2L) and 4,4′-bipyridine (4,4′-bipy) has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction, XRPD, IR, and elemental analysis. Temperature-dependent magnetic susceptibility and thermal degradation for 1 were also studied. The asymmetric unit of compound 1 consists of two crystallographically independent Co(II) ion, two L2− ligand, one 4,4′-bipy ligand, and three lattice water molecules. The 2D triangle networks were linked by the bridging 4,4′-bipy ligand to give rise to a 2-fold interpenetrated 3D architecture. The simplest cyclic motif of the 2D networks is a triangle ring consisting of three Co(II) cations and three L2− ligands. So we can define Co(II) ions as 4-connected nodes and the L2− ligands as 3-connected nodes. Thus, the 3D structure can be described as a 2-fold parallel interpenetrated ins InS 3,4-conn topology.
