Abstract

Nd(Re2Si)2 crystallizes in the orthorhombic Pnnm space group. The structure is three-dimensional. Nd is bonded in a 7-coordinate geometry to ten Re and seven Si atoms. There are a spread of Nd–Re bond distances ranging from 3.32–3.48 Å. There are a spread of Nd–Si bond distances ranging from 3.10–3.20 Å. There are four inequivalent Re sites. In the first Re site, Re is bonded to two equivalent Nd, eight Re, and two equivalent Si atoms to form distorted ReNd2Re8Si2 cuboctahedra that share corners with five equivalent ReNd3Re6Si3 cuboctahedra, edges with seven ReNd2Re8Si2 cuboctahedra, and faces with five ReNd2Re8Si2 cuboctahedra. There are a spread of Re–Re bond distances ranging from 2.59–2.98 Å. Both Re–Si bond lengths are 2.55 Å. In the second Re site, Re is bonded in a 12-coordinate geometry to three equivalent Nd, six Re, and three Si atoms. There are a spread of Re–Re bond distances ranging from 2.60–2.79 Å. There are one shorter (2.50 Å) and two longer (2.58 Å) Re–Si bond lengths. In the third Re site, Re is bonded in a 12-coordinate geometry to two equivalent Nd, eight Re, and three Si atoms. There are one shorter (2.74 Å) and two longer (2.86 Å) Re–Remore »« less
