The crystal structure described by La2Ni3 crystallizes in the orthorhombic Cmce space group. La(1) is bonded in a 8-coordinate geometry to four equivalent Ni(1) and six equivalent Ni(2) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 12-coordinate geometry to eight equivalent La(1) and four equivalent Ni(2) atoms. In the second Ni site, Ni(2) is bonded in a 10-coordinate geometry to six equivalent La(1), two equivalent Ni(1), and two equivalent Ni(2) atoms. is represented by the CIF file [CIF]
