Hydrothermal reactions of (E)-4-(2-(1H-imidazol-4-yl)vinyl)benzoic acid (HL) with Cd(II) and Mn(II) salts yield the complexes [Cd(L)2] (1) and [Mn(L)2] (2), which have been characterized by single-crystal and powder X-ray diffraction, IR spectroscopy, and elemental and thermogravimetric analyses. Complexes 1 and 2 are isomorphous and isostructural, displaying an uninodal 4-connected 8-fold interpenetrating 3D dia framework architecture with (66) topology. These frameworks exhibit high thermal stability up to 400 °C. The luminescence and non-linear optical (NLO) properties were investigated.
