Tb(CO2)3(CH2)3(CH)3 is Indium-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of twelve 02329_fluka molecules, twelve 02329_fluka molecules, and two Tb(CO2)3 clusters. In each Tb(CO2)3 cluster, Tb(1) is bonded in a 7-coordinate geometry to one O(1), one O(2), one O(3), one O(5), one O(6), and two equivalent O(4) atoms. The Tb(1)-O(1) bond length is 2.43 Å. The Tb(1)-O(2) bond length is 2.46 Å. The Tb(1)-O(3) bond length is 2.48 Å. The Tb(1)-O(5) bond length is 2.40 Å. The Tb(1)-O(6) bond length is 2.41 Å. There is one shorter (2.38 Å) and one longer (2.59 Å) Tb(1)-O(4) bond length. There are three 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 1.28 Å. The C(7)-O(2) bond length is 1.24 Å. In the second C site, C(8) is bonded in a distorted bent 120 degrees geometry to one O(3) and one O(4) atom. The C(8)-O(3) bond length is 1.24 Å. The C(8)-O(4) bond length is 1.26 Å. In the third C site, C(9) is bonded in a distorted bent 120 degrees geometry to one O(5) and one O(6) atom. The C(9)-O(5) bond length is 1.25 Å. The C(9)-O(6) bond length is 1.26 Å. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted L-shaped geometry to one Tb(1) and one C(7) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Tb(1) and one C(7) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one Tb(1) and one C(8) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to two equivalent Tb(1) and one C(8) atom. In the fifth O site, O(5) is bonded in a distorted L-shaped geometry to one Tb(1) and one C(9) atom. In the sixth O site, O(6) is bonded in a single-bond geometry to one Tb(1) and one C(9) atom.
