Crystal structure of bis(1,3-diaminopropane-κ2 N,N')bis[2-(4-nitrophenyl)acetato-κO]zinc(II)

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.
