Abstract

SmMo2Fe10N crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. Sm is bonded in a linear geometry to two equivalent Mo, ten Fe, and two equivalent N atoms. Both Sm–Mo bond lengths are 3.10 Å. There are two shorter (3.14 Å) and eight longer (3.29 Å) Sm–Fe bond lengths. Both Sm–N bond lengths are 2.41 Å. Mo is bonded in a 10-coordinate geometry to one Sm, one Mo, and twelve Fe atoms. The Mo–Mo bond length is 2.41 Å. There are a spread of Mo–Fe bond distances ranging from 2.66–2.95 Å. There are four inequivalent Fe sites. In the first Fe site, Fe is bonded in a single-bond geometry to two equivalent Mo, six Fe, and one N atom. There are four shorter (2.48 Å) and two longer (2.70 Å) Fe–Fe bond lengths. The Fe–N bond length is 1.92 Å. In the second Fe site, Fe is bonded in a single-bond geometry to two equivalent Mo, six Fe, and one N atom. There are four shorter (2.50 Å) and two longer (2.68 Å) Fe–Fe bond lengths. The Fe–N bond length is 1.92 Å. In the third Fe site, Fe is bonded to two equivalent Sm, two equivalent Mo,more »« less
