The crystal structure described by LaYNi10 crystallizes in the orthorhombic Pmmm space group. La(1) is bonded in a 18-coordinate geometry to two equivalent Ni(1), four equivalent Ni(2), four equivalent Ni(4), and eight equivalent Ni(5) atoms. Y(1) is bonded in a 18-coordinate geometry to two equivalent Ni(2), four equivalent Ni(1), four equivalent Ni(3), and eight equivalent Ni(5) atoms. There are five inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to one La(1), two equivalent Y(1), two equivalent Ni(3), and four equivalent Ni(5) atoms. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to two equivalent La(1), one Y(1), two equivalent Ni(4), and four equivalent Ni(5) atoms. In the third Ni site, Ni(3) is bonded to four equivalent Y(1), four equivalent Ni(1), and four equivalent Ni(5) atoms to form NiY4Ni8 cuboctahedra that share corners with four equivalent Ni(4)La4Ni8 cuboctahedra, corners with four equivalent Ni(3)Y4Ni8 cuboctahedra, corners with eight equivalent Ni(5)La2Y2Ni8 cuboctahedra, edges with two equivalent Ni(3)Y4Ni8 cuboctahedra, edges with eight equivalent Ni(5)La2Y2Ni8 cuboctahedra, faces with two equivalent Ni(3)Y4Ni8 cuboctahedra, and faces with eight equivalent Ni(5)La2Y2Ni8 cuboctahedra. In the fourth Ni site, Ni(4) is bonded to four equivalent La(1), four equivalent Ni(2), and four equivalent Ni(5) atoms to form NiLa4Ni8 cuboctahedra that share corners with four equivalent Ni(4)La4Ni8 cuboctahedra, corners with four equivalent Ni(3)Y4Ni8 cuboctahedra, corners with eight equivalent Ni(5)La2Y2Ni8 cuboctahedra, edges with two equivalent Ni(4)La4Ni8 cuboctahedra, edges with eight equivalent Ni(5)La2Y2Ni8 cuboctahedra, faces with two equivalent Ni(4)La4Ni8 cuboctahedra, and faces with eight equivalent Ni(5)La2Y2Ni8 cuboctahedra.
