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

Abstract

In the structure of the title compound, [Cd(C8H6NO4)2(C3H10N2)2], the CdII atom is located on a center of symmetry with one independent Cd—O distance of 2.3547 (17) Å and two Cd—N distances of 2.3265 (18) and 2.3449 (19) Å. The CdII atom has an overall octahedral coordination environment. Several types of hydrogen-bonding interactions are evident. Both intra- and intermolecular interactions occur between the amino groups and the O atoms of the acetate group. These N—H...O hydrogen bonds lead to a layered structure extending parallel to the bc plane. In addition, weak intermolecular C—H...O interactions involving the nitro groups exist, leading to the formation of a three-dimensional network structure.
