Abstract

In this work, a new zinc complex of N-(2-aminoethyl)-1,3-propanediamine (L), mer-R,S-[ZnL₂](NO₃)₂ (1), was prepared and identified by elemental analysis, FT-IR and Raman spectroscopy and single-crystal X-Ray diffraction. The zinc atom in 1 which is coordinated by four nitrogen atoms of the NH₂ groups and two nitrogen atoms of the NH groups has a distorted octahedral geometry. If the distortion in the [ZnL₂]²⁺ cation is disregarded, it has a C₂axis and C₂symmetry. The dihedral angle between two planes of the coordinated atoms of each ligand confirms the mer conformation. The N–H···O hydrogen bonds between the nitrate and amine groups are presented in the crystal network of 1.
