The crystal structure described by Al10Mn3 crystallizes in the hexagonal P6_3/mmc space group. Mn(1) is bonded to two equivalent Mn(1), two equivalent Al(1), two equivalent Al(2), and six equivalent Al(3) atoms to form distorted MnMn2Al10 cuboctahedra that share corners with four equivalent Mn(1)Mn2Al10 cuboctahedra, faces with two equivalent Al(1)Mn6Al6 cuboctahedra, and faces with six equivalent Mn(1)Mn2Al10 cuboctahedra. There are three inequivalent Al sites. In the first Al site, Al(2) is bonded in a distorted linear geometry to two equivalent Mn(1) and eight equivalent Al(3) atoms. In the second Al site, Al(1) is bonded to six equivalent Mn(1) and six equivalent Al(3) atoms to form AlMn6Al6 cuboctahedra that share faces with two equivalent Al(1)Mn6Al6 cuboctahedra and faces with six equivalent Mn(1)Mn2Al10 cuboctahedra. In the third Al site, Al(3) is bonded in a 13-coordinate geometry to three equivalent Mn(1), one Al(1), four equivalent Al(2), and five equivalent Al(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
