Fe3C24H12O25 is Magnesium structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is zero-dimensional and consists of two Fe3C24H12O25 clusters. Fe(1) is bonded to one O(3) and four equivalent O(1) atoms to form corner-sharing FeO5 square pyramids. The Fe(1)-O(3) bond length is 1.92 Å. All Fe(1)-O(1) bond lengths are 2.03 Å. There are three inequivalent C sites. In the first C site, C(2) is bonded in a distorted bent 120 degrees geometry to one C(3) and two equivalent O(1) atoms. The C(2)-C(3) bond length is 1.49 Å. Both C(2)-O(1) bond lengths are 1.26 Å. In the second C site, C(3) is bonded in a trigonal planar geometry to one C(2) and two equivalent C(1) atoms. Both C(3)-C(1) bond lengths are 1.37 Å. In the third C site, C(1) is bonded in a distorted single-bond geometry to one C(3) and one O(2) atom. The C(1)-O(2) bond length is 1.43 Å. H(1) is bonded in a single-bond geometry to one O(2) atom. The H(1)-O(2) bond length is 0.82 Å. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Fe(1) and one C(2) atom. In the second O site, O(2) is bonded in a water-like geometry to one C(1) and one H(1) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to three equivalent Fe(1) atoms.
