Materials Data on NbSi4Mo by Materials Project

NbMoSi4 is Titanium Disilicide-derived structured and crystallizes in the monoclinic P2 space group. The structure is three-dimensional. there are three inequivalent Nb5+ sites. In the first Nb5+ site, Nb5+ is bonded in a distorted q6 geometry to ten Si2- atoms. There are a spread of Nb–Si bond distances ranging from 2.60–2.79 Å. In the second Nb5+ site, Nb5+ is bonded in a distorted q6 geometry to ten Si2- atoms. There are a spread of Nb–Si bond distances ranging from 2.60–2.77 Å. In the third Nb5+ site, Nb5+ is bonded in a distorted q6 geometry to ten Si2- atoms. There are a spread of Nb–Si bond distances ranging from 2.60–2.78 Å. There are three inequivalent Mo3+ sites. In the first Mo3+ site, Mo3+ is bonded in a distorted q6 geometry to ten Si2- atoms. There are a spread of Mo–Si bond distances ranging from 2.57–2.78 Å.
