'''Titanium(III) phosphide''' (TiP) is an inorganic chemical compound of [[titanium]] and [[phosphorus]]. Normally encountered as a grey powder,<ref name = "Perry" /> it is high melting and a metallic conductor.<ref name = "Schnering">H.G. Von Schnering, W. Hönle ''Phosphides - Solid state chemistry'' Encyclopedia of Inorganic Chemistry Ed. R. Bruce King (1994) John wiley & Sons ISBN 0-471-93620-0</ref> It is not attacked by common acids or water.<ref name = "Perry" /> Its physical properties stand in contrast to the group 1 and group 2 phosphides that contain the P^{3<nowiki>&minus;</nowiki>} anion (such as [[sodium phosphide|Na₃P]]), which are not metallic and are readily hydrolysed.<ref name = "Schnering" /> Titanium phosphide is classified as a "metal-rich phosphide", where extra valence electrons from the metal are delocalised.<ref name = "Schnering" />
