CdC6H8(NI)2(C3H2)2 is Indium-derived structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two 2,3-dimethyl-1,3-butadiene molecules and two CdC6H8(NI)2 clusters. In each CdC6H8(NI)2 cluster, Cd(1) is bonded in a distorted tetrahedral geometry to one N(1), one N(2), one I(1), and one I(2) atom. The Cd(1)-N(1) bond length is 2.34 Å. The Cd(1)-N(2) bond length is 2.34 Å. The Cd(1)-I(1) bond length is 2.82 Å. The Cd(1)-I(2) bond length is 2.82 Å. There are three inequivalent C sites. In the first C site, C(11,12) is bonded in a distorted single-bond geometry to one C(1,2) and one H(5,6,11,12) atom. The C(11,12)-C(1,2) bond length is 1.40 Å. The C(11,12)-H(5,6,11,12) bond length is 1.09 Å. In the second C site, C(1,2) is bonded in a distorted trigonal planar geometry to one C(11,12); one C(3,4); and one N(1) atom. The C(1,2)-C(3,4) bond length is 1.40 Å. The C(1,2)-N(1) bond length is 1.42 Å. In the third C site, C(3,4) is bonded in a distorted single-bond geometry to one C(1,2) and one H(5,6,11,12) atom. The C(3,4)-H(5,6,11,12) bond length is 1.09 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 4-coordinate geometry to one Cd(1); one C(1,2); one H(1); and one H(3) atom. The N(1)-H(1) bond length is 1.03 Å. The N(1)-H(3) bond length is 1.03 Å. In the second N site, N(2) is bonded in a 4-coordinate geometry to one Cd(1); one C(1,2); one H(2); and one H(4) atom. The N(2)-C(1,2) bond length is 1.42 Å. The N(2)-H(2) bond length is 1.03 Å. The N(2)-H(4) bond length is 1.03 Å. There are five inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one N(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one N(2) atom. In the third H site, H(3) is bonded in a single-bond geometry to one N(1) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one N(2) atom. In the fifth H site, H(5,6,11,12) is bonded in a single-bond geometry to one C(3,4) atom. There are two inequivalent I sites. In the first I site, I(1) is bonded in a single-bond geometry to one Cd(1) atom. In the second I site, I(2) is bonded in a single-bond geometry to one Cd(1) atom.
