Materials Data on Ti3NO4 by Materials Project
Ti3NO4 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Ti+3.67+ sites. In the first Ti+3.67+ site, Ti+3.67+ is bonded to one N3- and five O2- atoms to form a mixture of distorted edge and corner-sharing TiNO5 octahedra. The corner-sharing octahedra tilt angles range from 24–50°. The Ti–N bond length is 1.97 Å. There are a spread of Ti–O bond distances ranging from 1.87–2.13 Å. In the second Ti+3.67+ site, Ti+3.67+ is bonded in a 6-coordinate geometry to two equivalent N3- and four O2- atoms. Both Ti–N bond lengths are 2.05 Å. There are two shorter (1.95 Å) and two longer (2.19 Å) Ti–O bond lengths. N3- is bonded to four Ti+3.67+ atoms to form distorted NTi4 trigonal pyramids that share corners with two equivalent NTi4 trigonal pyramids, corners with two equivalent OTi4 trigonal pyramids, and edges with four equivalent OTi4 trigonal pyramids. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to four Ti+3.67+ atoms to form distorted OTi4 trigonal pyramids that share a cornercorner with one NTi4 trigonal pyramid, corners with three equivalent OTi4 trigonal pyramids, edges with two equivalent NTi4 trigonal pyramids, and edges with two equivalent OTi4 trigonal pyramids. In the second O2- site, O2- is bonded in a 3-coordinate geometry to three Ti+3.67+ atoms.
