MoFeCl crystallizes in the trigonal R3m space group. Mo(1) is bonded in a 7-coordinate geometry to four equivalent Fe(1) and three equivalent Cl(1) atoms. There is one shorter (2.33 Å) and three longer (2.40 Å) Mo(1)-Fe(1) bond lengths. All Mo(1)-Cl(1) bond lengths are 2.29 Å. Fe(1) is bonded in a single-bond geometry to four equivalent Mo(1) and one Cl(1) atom. The Fe(1)-Cl(1) bond length is 1.27 Å. Cl(1) is bonded in a single-bond geometry to three equivalent Mo(1) and one Fe(1) atom.
