Zr2MnFe3 crystallizes in the trigonal R-3m space group. Zr(1) is bonded in a 16-coordinate geometry to four equivalent Zr(1), three equivalent Mn(1), and nine equivalent Fe(1) atoms. Mn(1) is bonded to six equivalent Zr(1) and six equivalent Fe(1) atoms to form MnZr6Fe6 cuboctahedra that share corners with six equivalent Mn(1)Zr6Fe6 cuboctahedra, corners with twelve equivalent Fe(1)Zr6Mn2Fe4 cuboctahedra, edges with six equivalent Mn(1)Zr6Fe6 cuboctahedra, and faces with eighteen equivalent Fe(1)Zr6Mn2Fe4 cuboctahedra. Fe(1) is bonded to six equivalent Zr(1), two equivalent Mn(1), and four equivalent Fe(1) atoms to form FeZr6Mn2Fe4 cuboctahedra that share corners with four equivalent Mn(1)Zr6Fe6 cuboctahedra, corners with fourteen equivalent Fe(1)Zr6Mn2Fe4 cuboctahedra, edges with six equivalent Fe(1)Zr6Mn2Fe4 cuboctahedra, faces with six equivalent Mn(1)Zr6Fe6 cuboctahedra, and faces with twelve equivalent Fe(1)Zr6Mn2Fe4 cuboctahedra.
