(C3H2)3(C5NH4)3Cd2C12H6(O2Cl)3 is Indium-derived structured and crystallizes in the trigonal P-31c space group. The structure is zero-dimensional and consists of six 2,3-dimethyl-1,3-butadiene molecules; twelve n,n-dimethylprop-1-en-2-amine molecules; and two Cd2C12H6(O2Cl)3 clusters. In each Cd2C12H6(O2Cl)3 cluster, there are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in an octahedral geometry to six equivalent Cl(1) atoms. All Cd(1)-Cl(1) bond lengths are 2.64 Å. In the second Cd site, Cd(2) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent Cl(1) atoms. Both Cd(2)-O(1) bond lengths are 2.46 Å. Both Cd(2)-O(2) bond lengths are 2.25 Å. Both Cd(2)-Cl(1) bond lengths are 2.54 Å. There are four inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 120 degrees geometry to one C(2), one O(1), and one O(2) atom. The C(1)-C(2) bond length is 1.51 Å. The C(1)-O(1) bond length is 1.24 Å. The C(1)-O(2) bond length is 1.23 Å. In the second C site, C(2) is bonded in a trigonal planar geometry to one C(1), one C(3), and one C(4) atom. The C(2)-C(3) bond length is 1.37 Å. The C(2)-C(4) bond length is 1.35 Å. In the third C site, C(3) is bonded in a distorted single-bond geometry to one C(2) and one H(1) atom. The C(3)-H(1) bond length is 0.95 Å. In the fourth C site, C(4) is bonded in a distorted single-bond geometry to one C(2) and one H(2) atom. The C(4)-H(2) bond length is 0.95 Å. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(3) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(4) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted L-shaped geometry to one Cd(2) and one C(1) atom. In the second O site, O(2) is bonded in a distorted water-like geometry to one Cd(2) and one C(1) atom. Cl(1) is bonded in an L-shaped geometry to one Cd(1) and one Cd(2) atom.
