Hydrothermal Synthesis, Crystal Structure and Properties of a 2D Network of Cd(II) Coordination Polymers with Helical Chains

چکیده
Hydrothermal reaction of Cd(II) acetate with the bridging ligand m-H4bptc (m-H4bptc = biphenyl-2,3′ ,3,4′-tetracarboxylic acid) yielded a new 2D metal-organic coordination polymer with helical chains in the solid state namely {[Cd2(m-bptc)(H2O)6]·(H2O)5}n (1). The helices are further connected through hydrogen bonds to give a threedimensional supramolecular network. The thermal stability of complex 1 was studied by thermogravimetric (TG) and differential thermal analysis (DTA). Compound 1 exhibits photoluminescence with an emission maximum at ca. 399 nm upon excitation at 360 nm.
