LiYMn4 crystallizes in the trigonal R3m space group. Li(1) is bonded in a 10-coordinate geometry to four equivalent Y(1), three equivalent Mn(1), and three equivalent Mn(2) atoms. There is one shorter (2.74 Å) and three longer (3.12 Å) Li(1)-Y(1) bond lengths. All Li(1)-Mn(1) bond lengths are 2.54 Å. All Li(1)-Mn(2) bond lengths are 2.94 Å. Y(1) is bonded in a 13-coordinate geometry to four equivalent Li(1), three equivalent Mn(2), and six equivalent Mn(1) atoms. All Y(1)-Mn(2) bond lengths are 2.90 Å. There are three shorter (2.57 Å) and three longer (2.71 Å) Y(1)-Mn(1) bond lengths. There are two inequivalent Mn sites. In the first Mn site, Mn(2) is bonded in a 9-coordinate geometry to three equivalent Li(1), three equivalent Y(1), and three equivalent Mn(1) atoms. All Mn(2)-Mn(1) bond lengths are 2.06 Å. In the second Mn site, Mn(1) is bonded in a 6-coordinate geometry to one Li(1), two equivalent Y(1), one Mn(2), and two equivalent Mn(1) atoms. Both Mn(1)-Mn(1) bond lengths are 1.19 Å.
