Materials Data on Fe(MoO5)2 by Materials Project

Fe(MoO5)2 crystallizes in the triclinic P-1 space group. The structure is one-dimensional and consists of one Fe(MoO5)2 ribbon oriented in the (0, 1, 0) direction. there are two inequivalent Mo sites. In the first Mo site, Mo is bonded to four O atoms to form MoO4 tetrahedra that share corners with two equivalent FeO6 octahedra. The corner-sharing octahedra tilt angles range from 13–33°. There are a spread of Mo–O bond distances ranging from 1.72–1.94 Å. In the second Mo site, Mo is bonded in a 5-coordinate geometry to five O atoms. There are a spread of Mo–O bond distances ranging from 1.70–2.15 Å. Fe is bonded to six O atoms to form distorted FeO6 octahedra that share corners with two equivalent MoO4 tetrahedra and an edgeedge with one FeO6 octahedra. There are a spread of Fe–O bond distances ranging from 1.85–2.21 Å. There are ten inequivalent O sites. In the first O site, O is bonded in a water-like geometry to two equivalent Fe atoms. In the second O site, O is bonded in a single-bond geometry to one Fe atom. In the third O site, O is bonded in a bent 150 degrees geometry to one Mo and one Fe atom. In the fourth O site, O is bonded in a single-bond geometry to one Mo atom. In the fifth O site, O is bonded in a linear geometry to one Mo and one Fe atom. In the sixth O site, O is bonded in a bent 150 degrees geometry to two Mo atoms. In the seventh O site, O is bonded in a 2-coordinate geometry to one Mo and one O atom. The O–O bond length is 1.37 Å. In the eighth O site, O is bonded in a distorted L-shaped geometry to one Mo and one O atom. In the ninth O site, O is bonded in a bent 150 degrees geometry to one Mo and one Fe atom. In the tenth O site, O is bonded in a single-bond geometry to one Mo atom.
