'''三碘化钛'''是一种[[无机化合物]]，化学式为TiI<sub>3</sub>。它是暗紫色固体，难溶于有机溶剂（除非被其分解）。它可由[[钛]]和[[碘]]反应制得：<ref name="brauer">F. Hein, S. Herzog "Molybdenum(III) Bromide" in Handbook of Preparative Inorganic Chemistry, 2nd Ed. Edited by G. Brauer, Academic Press, 1963, NY. Vol. 1. p. 1407.</ref>
:<math>\mathrm{2 \ Ti + 3 \ I_2 \longrightarrow 2 \ TiI_3}</math>
[[四碘化钛]]在700 °C被金属[[钛]]还原也能得到三碘化钛：<ref name=Ti>无机化学丛书 第八卷 钛分族 钒分族 铬分族. 科学出版社. 1.2.3 卤化物和卤氧化物. pp 27</ref>
:<math>\mathrm{ 3 \ TiI_4 + Ti \longrightarrow 4 \ TiI_3}</math>
它可以和[[二甲硫醚]]或[[四氢噻吩]]形成TiI<sub>3</sub>·2L配合物。<ref>{{cite journal|journal=Journal of the Chemical Society A: Inorganic, Physical, Theoretical|language=en|issn=0022-4944|date=1968|pages=198|doi=10.1039/j19680000198|url=http://xlink.rsc.org/?DOI=j19680000198|title=The preparation and magnetic and spectral properties of some antiferromagnetic thioether complexes of titanium(III)|accessdate=2021-01-12|author=G.
