  A two-dimensional coordination polymer lcub[Ca2(tzda)2(H2O)4] · 3H2Orcubn, where H2tzda is a flexible carboxylate ligand (1,3,4-thiadiazole-2,5-diyldithio)diacetic acid, was synthesized and characterized by X-ray crystallography, IR, TGA and photoluminescence. The results show that there are two crystallographically independent Ca atoms in the structure, which are both seven-coordinate, but with different coordination environments. Two kinds of tzda2- ligands with identical coordination mode exist in lcub[Ca2(tzda)2(H2O)4] · 3H2Orcubn. The η2-bridging O3 and O8 atoms link the Ca1 atoms into a 1-D chain, which are further connected by the tzda2- ligands forming a 2-D network. A series of hydrogen bonds link the 2-D network to form a 3-D architecture. The solid state luminescence behavior of lcub[Ca2(tzda)2(H2O)4] · 3H2Orcubn exhibits one intense emission band at 375 nm upon excitation at 315 nm which can be attributed to the intraligand emission.
