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.
