Titanium(III) phosphide (TiP) is an inorganic chemical compound of titanium and phosphorus. Normally encountered as a grey powder,[1] it is a metallic conductor with a high melting point.[2] It is not attacked by common acids or water.[1] Its physical properties stand in contrast to the group 1 and group 2 phosphides that contain the P3− anion (such as Na3P), which are not metallic and are readily hydrolysed.[2] Titanium phosphide is classified as a "metal-rich phosphide", where extra valence electrons from the metal are delocalised.[2]
Titanium phosphide can be prepared by the reaction of TiCl4 and PH3.[1]
There are other titanium phosphide phases, including Ti3P,[3] Ti2P,[4] Ti7P4,[5] Ti5P3,[6] and Ti4P3.[7]
Titanium phosphide should not be confused with titanium phosphate or titanium isopropoxide, both of which are sometimes known by the acronym TIP.
