Co(II) nitrate reacts with potassium 5-[(2-methyl-1H-imidazol-1-yl)methyl]isophthalate (K2L) under hydrothermal conditions to yield a new complex [Co(L)(H2O)] (1). In the presence of 2-(pyridin-2-yl)-1H-benzo[d]imidazole (pybim) as auxiliary ligand, complex [Cd(L)(pybim)] (2) can be obtained using Cd(NO3)2. Complexes 1 and 2 have been characterized by single-crystal and powder X-ray diffraction, IR, elemental and thermogravimetric analyses. Complex 1 exhibits a 2-fold interpenetrated 3D framework architecture with (10,3)-a topology; complex 2 consists of a 2D fes network with (4.82) topology. The fluorescence properties of 2 were also investigated.
