Abstract

In the structure of the title compound, [Cd(C8H6NO4)2(C3H10N2)2], the Cd(II) 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 Cd(II) atom has an overall octa-hedral coordination environment. Several types of hydrogen-bonding inter-actions are evident. Both intra- and inter-molecular inter-actions 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 inter-molecular C-H⋯O inter-actions involving the nitro groups exist, leading to the formation of a three-dimensional network structure.
