FeH2(C2O)3CH crystallizes in the trigonal P3_221 space group. The structure consists of six 02329_fluka molecules inside a FeH2(C2O)3 framework. In the FeH2(C2O)3 framework, Fe(1) is bonded to one O(3), two equivalent O(1), and two equivalent O(2) atoms to form distorted edge-sharing FeO5 square pyramids. The Fe(1)-O(3) bond length is 2.12 Å. There is one shorter (2.05 Å) and one longer (2.06 Å) Fe(1)-O(1) bond length. Both Fe(1)-O(2) bond lengths are 2.17 Å. There are six inequivalent C sites. In the first C site, C(1) is bonded in a single-bond geometry to one C(2) and one O(1) atom. The C(1)-C(2) bond length is 1.41 Å. The C(1)-O(1) bond length is 1.30 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(7) atom. The C(2)-C(3) bond length is 1.41 Å. The C(2)-C(7) bond length is 1.48 Å. In the third C site, C(3) is bonded in a distorted single-bond geometry to one C(2), one C(4), and one H(1) atom. The C(3)-C(4) bond length is 1.40 Å. The C(3)-H(1) bond length is 0.95 Å. In the fourth C site, C(4) is bonded in a trigonal planar geometry to one C(3), one C(4), and one C(5) atom. The C(4)-C(4) bond length is 1.47 Å. The C(4)-C(5) bond length is 1.41 Å. In the fifth C site, C(5) is bonded in a distorted single-bond geometry to one C(4) and one H(2) atom. The C(5)-H(2) bond length is 0.95 Å. In the sixth C site, C(7) is bonded in a bent 120 degrees geometry to one C(2), one O(2), and one O(3) atom. The C(7)-O(2) bond length is 1.16 Å. The C(7)-O(3) bond length is 1.29 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(2) is bonded in a single-bond geometry to one C(5) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent Fe(1) and one C(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Fe(1) and one C(7) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Fe(1) and one C(7) atom. Linkers: 3 [O]C(=O)c1cc(-c2ccc([O])c(C([O])=O)c2)ccc1[O]. Metal clusters: 6 [Fe].
