Abstract

ScCoGe2 crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. there are two inequivalent Sc sites. In the first Sc site, Sc is bonded in a 7-coordinate geometry to two equivalent Co and seven Ge atoms. Both Sc–Co bond lengths are 3.07 Å. There are a spread of Sc–Ge bond distances ranging from 2.74–2.93 Å. In the second Sc site, Sc is bonded in a 8-coordinate geometry to four Co and eight Ge atoms. There are a spread of Sc–Co bond distances ranging from 3.01–3.15 Å. There are a spread of Sc–Ge bond distances ranging from 2.70–2.98 Å. There are two inequivalent Co sites. In the first Co site, Co is bonded to four Sc, two equivalent Co, and six Ge atoms to form a mixture of distorted edge and face-sharing CoSc4Co2Ge6 cuboctahedra. Both Co–Co bond lengths are 2.70 Å. There are two shorter (2.46 Å) and four longer (2.52 Å) Co–Ge bond lengths. In the second Co site, Co is bonded in a 12-coordinate geometry to three equivalent Sc, one Co, and six Ge atoms. There are a spread of Co–Ge bond distances ranging from 2.37–2.56 Å. There are five inequivalent Ge sites. In the first Gemore »« less
