Abstract

Pr2Cu3Ga5 crystallizes in the tetragonal P-4m2 space group. The structure is three-dimensional. Pr is bonded in a 12-coordinate geometry to six Cu and ten Ga atoms. There are four shorter (3.30 Å) and two longer (3.35 Å) Pr–Cu bond lengths. There are a spread of Pr–Ga bond distances ranging from 3.26–3.35 Å. There are three inequivalent Cu sites. In the first Cu site, Cu is bonded in a 4-coordinate geometry to four equivalent Pr and four equivalent Ga atoms. All Cu–Ga bond lengths are 2.46 Å. In the second Cu site, Cu is bonded to four equivalent Pr and eight Ga atoms to form distorted CuPr4Ga8 cuboctahedra that share corners with four equivalent CuPr4Ga8 cuboctahedra, faces with four equivalent CuPr4Ga8 cuboctahedra, and faces with four equivalent GaPr4Ga4Cu4 cuboctahedra. There are four shorter (2.52 Å) and four longer (3.02 Å) Cu–Ga bond lengths. In the third Cu site, Cu is bonded in a 4-coordinate geometry to four equivalent Pr and four equivalent Ga atoms. All Cu–Ga bond lengths are 2.46 Å. There are three inequivalent Ga sites. In the first Ga site, Ga is bonded in a 9-coordinate geometry to four equivalent Pr, two equivalent Cu, and three Ga atoms.
