Synthesis and structure characterization of zinc and cadmium dipeptide coordination polymers
wo new coordination polymers, Zn(Gly-L-Phe)2 and Cd(Gly-L-Phe)2 (Gly-L-Phe = glycyl-L- phenylalanine), have been synthesized by the reaction of Zn(NO3)2·6H2O or Cd(NO3)2·6H2O, NaOH and glycyl-L-phenylalanine. The obtained materials were characterized by infrared spectroscopy, thermal analysis, atomic absorption spectroscopy, while crystal structures were determined from powder X-ray diffraction data. Both products crystallize in the chiral monoclinic C2 space group, having similar unit cell parameters, forming a two- dimensional coordination network, two of which are interpenetrated giving a non-porous structure. Both products show enhanced thermal stability (over 300 °C).
