Abstract
Reactions of cadmium(II) with 5-(4-carboxybenzylamino)isophthalic acid (H3L) in the presence of 2-(pyridin-2-yl)-1H-benzo[d]imidazole (pybim) and 2,2′-bipyridine (bpy) by hydrothermal method lead to two complexes, [Cd(HL)(pybim)]·H2O (1) and [Cd2(L)(HCOO)(bpy)2(H2O)]·H2O (2). Complexes 1 and 2 have been characterized by single-crystal and powder X-ray diffraction, Infrared spectra, and elemental and thermogravimetric analyses. 1 has a double-chain structure while 2 consists of uninodal 3-connected 2-D hcb networks with (63) topology. Luminescence and sorption properties of 1 and 2 were also investigated.
