The material structure described by Er2Mn3Ga crystallizes in the trigonal R-3m space group. Er(1) is bonded in a 16-coordinate geometry to four equivalent Er(1), nine equivalent Mn(1), and three equivalent Ga(1) atoms. Mn(1) is bonded to six equivalent Er(1), four equivalent Mn(1), and two equivalent Ga(1) atoms to form MnEr6Mn4Ga2 cuboctahedra that share corners with four equivalent Ga(1)Er6Mn6 cuboctahedra, corners with fourteen equivalent Mn(1)Er6Mn4Ga2 cuboctahedra, edges with six equivalent Mn(1)Er6Mn4Ga2 cuboctahedra, faces with six equivalent Ga(1)Er6Mn6 cuboctahedra, and faces with twelve equivalent Mn(1)Er6Mn4Ga2 cuboctahedra. Ga(1) is bonded to six equivalent Er(1) and six equivalent Mn(1) atoms to form GaEr6Mn6 cuboctahedra that share corners with six equivalent Ga(1)Er6Mn6 cuboctahedra, corners with twelve equivalent Mn(1)Er6Mn4Ga2 cuboctahedra, edges with six equivalent Ga(1)Er6Mn6 cuboctahedra, and faces with eighteen equivalent Mn(1)Er6Mn4Ga2 cuboctahedra. is represented by the CIF file [CIF]
