U(CO2)4(CH2)2(C3NH7)2(C3NH6)2 is Indium-derived structured and crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of eight 02329_fluka molecules, eight trimethylamine molecules, eight trimethylammonium molecules, and four U(CO2)4 clusters. In each U(CO2)4 cluster, U(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(3) atoms. Both U(1)-O(1) bond lengths are 2.37 Å. Both U(1)-O(3) bond lengths are 2.38 Å. There are two inequivalent C sites. In the first C site, C(7) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. The C(7)-O(1) bond length is 1.27 Å. The C(7)-O(2) bond length is 1.23 Å. In the second C site, C(9) is bonded in a distorted bent 120 degrees geometry to one O(3) and one O(4) atom. The C(9)-O(3) bond length is 1.28 Å. The C(9)-O(4) bond length is 1.22 Å. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to one U(1) and one C(7) atom. In the second O site, O(2) is bonded in a single-bond geometry to one C(7) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one U(1) and one C(9) atom. In the fourth O site, O(4) is bonded in a single-bond geometry to one C(9) atom.
