Solvothermal syntheses, crystal structures, thermal and photoluminescent properties of four coordination polymers constructed from mercapto-thiadiazole ligand

Constructed from mercapto-thiadiazole ligand, two twofold penetrated 3D complexes [Zn(3-ptt)2]n (1) and [Co(3-ptt)2]n (2), an interconnected 1D complex [Ni(3-ptt)2]n (3) and one mononuclear complex [Pb(3-ptt)2] (4) were obtained. The thermal stabilities of complexes 1-4 and luminescence properties of the complexes and ligand in the solid state have also been investigated in detail.
