CdH8(C2O)8(CH2)4(C3NH4)4 is Indium-derived structured and crystallizes in the tetragonal P-4n2 space group. The structure is zero-dimensional and consists of eight 02329_fluka molecules, eight trimethylamine molecules, and two CdH8(C2O)8 clusters. In each CdH8(C2O)8 cluster, Cd(1) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. All Cd(1)-O(1) bond lengths are 2.25 Å. There are four inequivalent C sites. In the first C site, C(1) is bonded in a bent 120 degrees geometry to one C(2), one O(1), and one O(2) atom. The C(1)-C(2) bond length is 1.53 Å. The C(1)-O(1) bond length is 1.25 Å. The C(1)-O(2) bond length is 1.25 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(6) atom. The C(2)-C(3) bond length is 1.38 Å. The C(2)-C(6) bond length is 1.38 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 0.93 Å. In the fourth C site, C(6) is bonded in a distorted single-bond geometry to one C(2) and one H(4) atom. The C(6)-H(4) bond length is 0.93 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(4) is bonded in a single-bond geometry to one C(6) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a water-like geometry to one Cd(1) and one C(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one C(1) atom.
