Yb4Mn3 crystallizes in the trigonal P-3 space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 7-coordinate geometry to two equivalent Mn(1) and five equivalent Mn(2) atoms. In the second Yb site, Yb(2) is bonded in a 4-coordinate geometry to one Mn(3) and three equivalent Mn(2) atoms. There are three inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 9-coordinate geometry to six equivalent Yb(1) and three equivalent Mn(2) atoms. In the second Mn site, Mn(2) is bonded in a 9-coordinate geometry to three equivalent Yb(2), five equivalent Yb(1), and one Mn(1) atom. In the third Mn site, Mn(3) is bonded in a 6-coordinate geometry to six equivalent Yb(2) atoms.
