In the title compound, [MoBr(2)(C(12)H(11)N(2))(C(12)H(10)N(2))(C(5)H(7)O(2))], the Mo(VI) atom is six-coordinated in a distorted octa-hedral geometry by two N atoms from the diphenyl-hydrazide(1-) and diphenyl-hydrazide(2-) ligands, two O atoms from a bidentate acetyl-acetonate ligand and two Br(-) ions. The mol-ecules form an inversion dimer via a pair of weak C-H⋯O hydrogen bonds and a π-π stacking inter-action with a centroid-centroid distance of 3.7401 (12) Å. Weak intra-molecular C-H⋯Br inter-actions and an intra-molecular π-π stacking inter-action with a centroid-centroid distance of 3.8118 (15) Å are also observed.
