Materials Data on TiP2 by Materials Project
TiP2 is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Ti4+ is bonded in a 9-coordinate geometry to nine P2- atoms. There are a spread of Ti–P bond distances ranging from 2.52–2.67 Å. There are two inequivalent P2- sites. In the first P2- site, P2- is bonded in a 7-coordinate geometry to five equivalent Ti4+ and two equivalent P2- atoms. Both P–P bond lengths are 2.59 Å. In the second P2- site, P2- is bonded in a 8-coordinate geometry to four equivalent Ti4+ and four P2- atoms. Both P–P bond lengths are 2.35 Å.
