Titanium(II) oxide (TiO) is an inorganic chemical compound of titanium and oxygen. It can be prepared from titanium dioxide and titanium metal at 1500°C.Egon Wiberg, Arnold Frederick Holleman (2001) "Inorganic Chemistry", Elsevier ISBN 0123526515] It is non-stoichiometric in a range TiO0.7 to TiO1.3 and this is caused by vacancies of either Ti or O in the defect rock salt structure. In pure TIO 15% of both Ti and O sites are vacant. Careful annealing can cause ordering of the vacancies producing a monoclinic form which has 5 TiO units in the primitive cell that exhibits higher resistivity [Electrical and Magnetic Properties of TiO and VO, Banus M. D., Reed T. B., Strauss A. J., Phys. Rev. B 5, 2775 - 2784, (1972)doi|10.1103/PhysRevB.5.2775] There is also a high temperature form with titanium atoms with trigonal prismatic coordination. [Greenwood&Earnshaw] Acid solutions of TiO are stable for a short then decompose to give hydrogen:

:Ti2+ + H+ → Ti3+ + ½ H2
