چکیده

The hydrothermal reactions of 5-(benzimidazol-1-ylmethyl)isophthalic acid (H2L) with Zn(II) and Cd(II) salts lead to the formation of the two new complexes [Cd(L)] (1) and [Zn(L)] (2). In the presence of 2-(pyridin-2-yl)-1H-benzimidazole (pybim) as auxiliary ligand, complex [Zn(L)(pybim)] (3) was obtained. Complexes 1–3 have been characterized by single-crystal and powder X-ray diffraction, IR spectroscopy, and elemental and thermogravimetric analyses. Complexes 1 and 2 are isostructural and exhibit a binodal (3,6)-connected 2D kgd network structure with (4)2(4.6.8) topology; 3 consists of uninodal 3-connected 2D (63) hcb networks. The influential factors of synthetic strategies on the coordination modes of the ligands and on the structures and properties of the resulting complexes are discussed. The luminescence properties of 1–3 were investigated.
