Abstract
Mo2Ni3Si is Hexagonal Laves-derived structured and crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are four inequivalent Mo sites. In the first Mo site, Mo is bonded in a 12-coordinate geometry to four Mo, ten Ni, and two equivalent Si atoms. There are a spread of Mo–Mo bond distances ranging from 2.77–2.93 Å. There are a spread of Mo–Ni bond distances ranging from 2.71–2.84 Å. Both Mo–Si bond lengths are 2.76 Å. In the second Mo site, Mo is bonded in a 12-coordinate geometry to four Mo, eight Ni, and four equivalent Si atoms. There are one shorter (2.86 Å) and two longer (2.93 Å) Mo–Mo bond lengths. There are a spread of Mo–Ni bond distances ranging from 2.71–2.79 Å. There are two shorter (2.73 Å) and two longer (2.79 Å) Mo–Si bond lengths. In the third Mo site, Mo is bonded in a 12-coordinate geometry to four Mo, eight Ni, and four equivalent Si atoms. There are one shorter (2.84 Å) and two longer (2.93 Å) Mo–Mo bond lengths. There are a spread of Mo–Ni bond distances ranging from 2.71–2.79 Å. There are two shorter (2.73 Å) and two longer (2.79 Å) Mo–Si bond lengths.more »
