CdC6H6(NO2)2(C3H2)2 crystallizes in the tetragonal I4_122 space group. The structure consists of four 2,3-dimethyl-1,3-butadiene molecules inside a CdC6H6(NO2)2 framework. In the CdC6H6(NO2)2 framework, Cd(1) is bonded in an octahedral geometry to two equivalent N(1) and four equivalent O(1) atoms. Both Cd(1)-N(1) bond lengths are 2.33 Å. All Cd(1)-O(1) bond lengths are 2.37 Å. There are two inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to one H(1) and two equivalent O(1) atoms. The C(1)-H(1) bond length is 1.11 Å. Both C(1)-O(1) bond lengths are 1.27 Å. In the second C site, C(2) is bonded in a distorted bent 120 degrees geometry to one N(1) and one H(2) atom. The C(2)-N(1) bond length is 1.35 Å. The C(2)-H(2) bond length is 1.09 Å. N(1) is bonded in a trigonal planar geometry to one Cd(1) and two equivalent C(2) atoms. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(2) atom. O(1) is bonded in a distorted bent 120 degrees geometry to one Cd(1) and one C(1) atom. Linkers: 1 c1cc(-c2ccncc2)ccn1 ,4 [O]C=O. Metal clusters: 2 [Cd].
