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 NH 2 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 C2 axis and C2 symmetry. 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.
