Crystal structure of bis(1,3-diaminopropane-κ2N,N′)bis[2-(4-nitrophenyl)acetato-κO]zinc(II)

Abstract

In the structure of the title compound, [Zn(C8H6NO4)2(C3H10N2)2], the ZnII atom is located on a center of symmetry with one independent Zn—O distance of 2.199 (2) Å, and two Zn—N distances of 2.157 (2) and 2.144 (2) Å. The overall coordination geometry around the ZnII atom is octahedral. Several types of hydrogen-bonding interactions are evident. Both intramolecular [2.959 (3) Å] and intermolecular [3.118 (3) and 3.124 (3) Å interactions occur between the O atoms of the acetate group and the amino N atoms, and weak intermolecular C—H—O interactions involving the nitro groups, leading to an extended chain of the molecules aligned along the ac plane.
