Materials Data on Mn2GaCu3 by Materials Project
Abstract
Mn2Cu3Ga is Hexagonal Laves-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Mn is bonded in a 12-coordinate geometry to four equivalent Mn, nine equivalent Cu, and three equivalent Ga atoms. There are one shorter (2.96 Å) and three longer (2.99 Å) Mn–Mn bond lengths. There are three shorter (2.81 Å) and six longer (2.86 Å) Mn–Cu bond lengths. All Mn–Ga bond lengths are 2.87 Å. Cu is bonded to six equivalent Mn, four equivalent Cu, and two equivalent Ga atoms to form CuMn6Ga2Cu4 cuboctahedra that share corners with four equivalent GaMn6Cu6 cuboctahedra, corners with fourteen equivalent CuMn6Ga2Cu4 cuboctahedra, edges with six equivalent CuMn6Ga2Cu4 cuboctahedra, faces with six equivalent GaMn6Cu6 cuboctahedra, and faces with twelve equivalent CuMn6Ga2Cu4 cuboctahedra. There are two shorter (2.38 Å) and two longer (2.52 Å) Cu–Cu bond lengths. Both Cu–Ga bond lengths are 2.45 Å. Ga is bonded to six equivalent Mn and six equivalent Cu atoms to form GaMn6Cu6 cuboctahedra that share corners with twelve equivalent CuMn6Ga2Cu4 cuboctahedra, edges with six equivalent GaMn6Cu6 cuboctahedra, faces with two equivalent GaMn6Cu6 cuboctahedra, and faces with eighteen equivalent CuMn6Ga2Cu4 cuboctahedra.
