Abstract

Gd2Mn17C3 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Gd is bonded in a trigonal planar geometry to four Mn and three equivalent C atoms. There are one shorter (3.20 Å) and three longer (3.38 Å) Gd–Mn bond lengths. All Gd–C bond lengths are 2.49 Å. There are four inequivalent Mn sites. In the first Mn site, Mn is bonded to two equivalent Gd and ten Mn atoms to form distorted MnGd2Mn10 cuboctahedra that share corners with four equivalent MnGd2Mn10 cuboctahedra, corners with two equivalent CGd2Mn4 octahedra, faces with four equivalent MnGd2Mn10 cuboctahedra, and faces with four equivalent CGd2Mn4 octahedra. The corner-sharing octahedral tilt angles are 47°. There are a spread of Mn–Mn bond distances ranging from 2.42–2.65 Å. In the second Mn site, Mn is bonded in a single-bond geometry to four Mn and one C atom. Both Mn–Mn bond lengths are 2.67 Å. The Mn–C bond length is 1.90 Å. In the third Mn site, Mn is bonded in a single-bond geometry to three Mn and one C atom. The Mn–Mn bond length is 2.58 Å. The Mn–C bond length is 1.90 Å. In the fourth Mn site, Mn is bonded in a 1-coordinate geometrymore »« less
