Abstract

SmTiFe11C crystallizes in the orthorhombic Imm2 space group. The structure is three-dimensional. Sm is bonded in a distorted linear geometry to one Ti, ten Fe, and two equivalent C atoms. The Sm–Ti bond length is 3.18 Å. There are a spread of Sm–Fe bond distances ranging from 3.08–3.31 Å. Both Sm–C bond lengths are 2.45 Å. Ti is bonded in a 1-coordinate geometry to one Sm and thirteen Fe atoms. There are a spread of Ti–Fe bond distances ranging from 2.35–2.95 Å. There are six inequivalent Fe sites. In the first Fe site, Fe is bonded in a single-bond geometry to six Fe and one C atom. There are four shorter (2.47 Å) and two longer (2.63 Å) Fe–Fe bond lengths. The Fe–C bond length is 1.90 Å. In the second Fe site, Fe is bonded in a single-bond geometry to two equivalent Ti, six Fe, and one C atom. There are four shorter (2.49 Å) and two longer (2.64 Å) Fe–Fe bond lengths. The Fe–C bond length is 1.91 Å. In the third Fe site, Fe is bonded in a single-bond geometry to one Ti, six Fe, and one C atom. There are a spread of Fe–Fe bond distancesmore »« less
