Crystal structure of bis-(1,3-di-amino-propane-κ(2) N,N')bis-[2-(4-nitro-phen-yl)acetato-κO]zinc(II).

In the structure of the title compound, [Zn(C8H6NO4)2(C3H10N2)2], the Zn(II) 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 Zn(II) atom is octa-hedral. Several types of hydrogen-bonding inter-actions are evident. Both intra-molecular [2.959 (3) Å] and inter-molecular [3.118 (3) and 3.124 (3) Šinter-actions occur between the O atoms of the acetate group and the amino N atoms, and weak inter-molecular C-H-O inter-actions involving the nitro groups, leading to an extended chain of the molecules aligned along the ac plane.
