Materials Data on Ti3Ni4 by Materials Project
Ni4Ti3 is delta Molybdenum Boride-like structured and crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Ti is bonded in a 9-coordinate geometry to nine Ni atoms. There are a spread of Ti–Ni bond distances ranging from 2.44–2.72 Å. There are three inequivalent Ni sites. In the first Ni site, Ni is bonded in a 6-coordinate geometry to six equivalent Ti and eight Ni atoms. There are two shorter (2.52 Å) and six longer (2.92 Å) Ni–Ni bond lengths. In the second Ni site, Ni is bonded in a 8-coordinate geometry to six equivalent Ti and two equivalent Ni atoms. In the third Ni site, Ni is bonded in a 7-coordinate geometry to seven equivalent Ti and one Ni atom.
