The compound described by Ti2NiCu is beta-prime cadmium gold-derived structured and crystallizes in the orthorhombic Pmm2 space group. There are two inequivalent Ti sites. In the first Ti site, Ti(1) is bonded in a distorted body-centered cubic geometry to four equivalent Ni(1) and four equivalent Cu(1) atoms. In the second Ti site, Ti(2) is bonded in a distorted body-centered cubic geometry to four equivalent Ni(1) and four equivalent Cu(1) atoms. Ni(1) is bonded in a 8-coordinate geometry to four equivalent Ti(1) and four equivalent Ti(2) atoms. Cu(1) is bonded in a 8-coordinate geometry to four equivalent Ti(1) and four equivalent Ti(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
