(Ti2H3(CO)7)2C3H2 crystallizes in the hexagonal P6/mmm space group. The structure consists of six propane molecules inside a Ti2H3(CO)7 framework. In the Ti2H3(CO)7 framework, there are two inequivalent Ti sites. In the first Ti site, Ti(1) is bonded to one O(3), one O(4), two equivalent O(1), and two equivalent O(5) atoms to form a mixture of distorted edge and corner-sharing TiO6 octahedra. The corner-sharing octahedral tilt angles range from 3-48°. The Ti(1)-O(3) bond length is 2.26 Å. The Ti(1)-O(4) bond length is 1.81 Å. Both Ti(1)-O(1) bond lengths are 2.01 Å. Both Ti(1)-O(5) bond lengths are 1.89 Å. In the second Ti site, Ti(2) is bonded to one O(5), one O(6), two equivalent O(2), and two equivalent O(3) atoms to form a mixture of distorted edge and corner-sharing TiO6 octahedra. The corner-sharing octahedral tilt angles range from 12-42°. The Ti(2)-O(5) bond length is 2.18 Å. The Ti(2)-O(6) bond length is 1.81 Å. Both Ti(2)-O(2) bond lengths are 2.11 Å. Both Ti(2)-O(3) bond lengths are 1.89 Å. There are four inequivalent C sites. In the first C site, C(5) is bonded in a distorted single-bond geometry to two equivalent C(4) and one H(3) atom. Both C(5)-C(4) bond lengths are 1.40 Å. The C(5)-H(3) bond length is 1.09 Å. In the second C site, C(4) is bonded in a trigonal planar geometry to one C(3), one C(5), and one C(6) atom. The C(4)-C(3) bond length is 1.40 Å. The C(4)-C(6) bond length is 1.49 Å. In the third C site, C(6) is bonded in a bent 120 degrees geometry to one C(4), one O(1), and one O(2) atom. The C(6)-O(1) bond length is 1.28 Å. The C(6)-O(2) bond length is 1.27 Å. In the fourth C site, C(3) is bonded in a single-bond geometry to one C(4) and one H(2) atom. The C(3)-H(2) bond length is 1.09 Å. There are two inequivalent H sites. In the first H site, H(2) is bonded in a single-bond geometry to one C(3) atom. In the second H site, H(3) is bonded in a single-bond geometry to one C(5) atom. There are six inequivalent O sites. In the first O site, O(2) is bonded in a bent 120 degrees geometry to one Ti(2) and one C(6) atom. In the second O site, O(4) is bonded in a linear geometry to two equivalent Ti(1) atoms. In the third O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Ti(1) and one C(6) atom. In the fourth O site, O(5) is bonded in a distorted trigonal non-coplanar geometry to one Ti(2) and two equivalent Ti(1) atoms. In the fifth O site, O(6) is bonded in a linear geometry to two equivalent Ti(2) atoms. In the sixth O site, O(3) is bonded in a distorted T-shaped geometry to one Ti(1) and two equivalent Ti(2) atoms. Linkers: 6 [O]C(=O)c1cc(Cc2cc(C([O])=O)cc(C([O])=O)c2)cc(C([O])=O)c1.
