Abstract

Abstract : A twofold (black, red) interpenetrated network of a Zn(Gly-l -Phe)2 coordination polymer, with hydrogen bonds (green) between neighboring layers. Abstract : Two 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 ·6H2 O or Cd(NO3 )2 ·6H2 O, 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 C 2 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).
