LaMn2Ni3 crystallizes in the hexagonal P6/mmm space group. La(1) is bonded in a 18-coordinate geometry to six equivalent Mn(1) and twelve equivalent Ni(1) atoms. Mn(1) is bonded in a 9-coordinate geometry to three equivalent La(1) and six equivalent Ni(1) atoms. Ni(1) is bonded to four equivalent La(1) and four equivalent Mn(1) atoms to form a mixture of distorted edge, corner, and face-sharing NiLa4Mn4 cuboctahedra.
