AlC4H8O2Cl3 is Indium-like structured and crystallizes in the monoclinic P2_1/m space group. The structure is zero-dimensional and consists of two AlC4H8O2Cl3 clusters. Al(1) is bonded in a trigonal bipyramidal geometry to two equivalent O(1), one Cl(1), one Cl(2), and one Cl(3) atom. Both Al(1)-O(1) bond lengths are 2.07 Å. The Al(1)-Cl(1) bond length is 2.15 Å. The Al(1)-Cl(2) bond length is 2.15 Å. The Al(1)-Cl(3) bond length is 2.16 Å. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted trigonal non-coplanar geometry to one H(1,3); one H(2,4); and one O(1) atom. The C(1)-H(1,3) bond length is 1.10 Å. The C(1)-H(2,4) bond length is 1.10 Å. The C(1)-O(1) bond length is 1.46 Å. In the second C site, C(2) is bonded in a distorted trigonal non-coplanar geometry to one H(1,3); one H(2,4); and one O(1) atom. The C(2)-H(1,3) bond length is 1.10 Å. The C(2)-H(2,4) bond length is 1.10 Å. The C(2)-O(1) bond length is 1.46 Å. There are two inequivalent H sites. In the first H site, H(1,3) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(2,4) is bonded in a single-bond geometry to one C(1) atom. O(1) is bonded in a distorted trigonal non-coplanar geometry to one Al(1), one C(1), and one C(2) atom. There are three inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a single-bond geometry to one Al(1) atom. In the second Cl site, Cl(2) is bonded in a single-bond geometry to one Al(1) atom. In the third Cl site, Cl(3) is bonded in a single-bond geometry to one Al(1) atom. Linkers: 2 C1COCCO1.
