LaNi2In crystallizes in the orthorhombic Pmma space group. La(1) is bonded in a 13-coordinate geometry to three equivalent Ni(1), four equivalent Ni(2), and six equivalent In(1) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to three equivalent La(1), four equivalent Ni(2), and two equivalent In(1) atoms. In the second Ni site, Ni(2) is bonded to four equivalent La(1), two equivalent Ni(2), four equivalent Ni(1), and two equivalent In(1) atoms to form a mixture of edge, face, and corner-sharing NiLa4In2Ni6 cuboctahedra. In(1) is bonded in a 10-coordinate geometry to six equivalent La(1), two equivalent Ni(1), and two equivalent Ni(2) atoms.
LaNi2In crystallizes in the orthorhombic Pmma space group. La(1) is bonded in a 13-coordinate geometry to three equivalent Ni(1), four equivalent Ni(2), and six equivalent In(1) atoms. There is one shorter (2.69 Å) and two longer (2.89 Å) La(1)-Ni(1) bond lengths. All La(1)-Ni(2) bond lengths are 3.12 Å. There are four shorter (3.37 Å) and two longer (3.48 Å) La(1)-In(1) bond lengths. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to three equivalent La(1), four equivalent Ni(2), and two equivalent In(1) atoms. All Ni(1)-Ni(2) bond lengths are 2.56 Å. Both Ni(1)-In(1) bond lengths are 2.64 Å. In the second Ni site, Ni(2) is bonded to four equivalent La(1), two equivalent Ni(2), four equivalent Ni(1), and two equivalent In(1) atoms to form a mixture of edge, face, and corner-sharing NiLa4In2Ni6 cuboctahedra. Both Ni(2)-Ni(2) bond lengths are 2.63 Å. Both Ni(2)-In(1) bond lengths are 2.74 Å.
