A novel metal-organic framework (MOF) {[Ag-2(HPIDC)]}(n) (1), based on a T-shaped tripodal ligand 2(pyridin-4-yl)-1H-imidazole-4,5-dicarboxylaic acid (H3PIDC), has been synthesized by hydrothermal method. The crystal structure of complex 1 is a three-connected net with the vertex symbol of (10(2).10(4).10(4)), which represents ThSi2 (10(3)-b) network topology. Complex 1 crystallizes in the noncentric space group (C-c), which belongs to the polar point group (C-s). The experimental results clearly show second-order nonlinear optical effects and ferroelectric feature. In addition, the photoluminescence of complex 1 was studied in solid state at room temperature.
