In the first C site, C(1) is bonded in a trigonal planar geometry to one H(1), one O(1), and one O(3) atom. In the second C site, C(2) is bonded in a trigonal planar geometry to one H(2) and two equivalent O(2) atoms. In the third C site, C(3) is bonded in a trigonal planar geometry to one H(3), one O(4), and one O(6) atom. In the fourth C site, C(4) is bonded in a trigonal planar geometry to one H(4) and two equivalent O(5) atoms. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(2) atom. In the third H site, H(3) is bonded in a single-bond geometry to one C(3) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one C(4) atom. There are six 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(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Fe(1) and one C(2) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Fe(1) and one C(1) atom. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to one Fe(1) and one C(3) atom. In the fifth O site, O(5) is bonded in a bent 120 degrees geometry to one Fe(1) and one C(4) atom.
