Materials Data on FeMo6C8(NO10)2 by Materials Project
Fe(Mo3O10)2(C4N)2 crystallizes in the monoclinic C2/m space group. The structure is two-dimensional and consists of four C4N clusters and two Fe(Mo3O10)2 sheets oriented in the (1, 0, 0) direction. In each C4N cluster, there are three inequivalent C1+ sites. In the first C1+ site, C1+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.51 Å. In the second C1+ site, C1+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.77 Å. In the third C1+ site, C1+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.77 Å. N3- is bonded in a 2-coordinate geometry to four C1+ atoms. In each Fe(Mo3O10)2 sheet, there are two inequivalent Mo6+ sites. In the first Mo6+ site, Mo6+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Mo–O bond distances ranging from 1.72–2.11 Å. In the second Mo6+ site, Mo6+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Mo–O bond distances ranging from 1.71–2.09 Å. Fe2+ is bonded in an octahedral geometry to six O2- atoms. There are two shorter (2.00 Å) and four longer (2.02 Å) Fe–O bond lengths. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one Mo6+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Mo6+ atoms. In the third O2- site, O2- is bonded in a distorted water-like geometry to two Mo6+ atoms. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one Mo6+ and one Fe2+ atom. In the fifth O2- site, O2- is bonded in a single-bond geometry to one Mo6+ atom. In the sixth O2- site, O2- is bonded in a distorted T-shaped geometry to three Mo6+ atoms. In the seventh O2- site, O2- is bonded in a bent 150 degrees geometry to one Mo6+ and one Fe2+ atom.
