'''三溴化钼'''是一种[[无机化合物]]，化学式为MoBr<sub>3</sub>。它是黑色固体，难溶于大多数溶剂，但可溶于配位性溶剂（即给体溶剂）。

==制备==
三溴化钼可由[[钼]]和[[溴]]在{{convert|350|C|F}}反应得到：<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 \ Mo + 3 \ Br_2 \longrightarrow 2 \ MoBr_3}</math>

它具有由无限衍生的链组成的[[八面体]]结构构成，具有交替Mo-Mo短键和长键连接。[[钌]]和[[锝]]的三溴化物有相同的结构。<ref name="DOI10.1016/0022-4596(72)90156-9">Dietrich Babel: ''Die Verfeinerung der MoBr<sub>3</sub>-Struktur (Refinement of the MoBr<sub>3</sub>-Structure)'' In: ''[[Journal of Solid State Chemistry]].'' 1972, volume 4, S.&nbsp;410–416, {{DOI|10.1016/0022-4596(72)90156-9}}.</ref><ref>Order-Disorder Transformation in RuBr<sub>3</sub> and MoBr<sub>3</sub>: A two-Dimensional Ising Model" Merlino, S.; Labella, L.; Marchetti, F.; Toscani, S.
