Crystal structure of bromido(η⁶-1-isopropyl-4-methylbenzene)(7-oxocyclohepta-1,3,5-trien-1-olato-κ²O,O')osmium.

ABSTRACT: In the title compound, [OsBr(C₁₀H₁₄)(C₇H₅O₂)], the central Os^II ion is ligated by a hexa-haptic η⁶p-cymene ring, a Br^- ligand and two O atoms of a chelating tropolonate group. The p-cymene ligand presents more than one conformation, giving rise to a discrete disorder, which was modelled with two different orientations with occupancy values of 0.561 (15) and 0.439 (15). The crystal packing features C-H⋯O and C-H⋯Br hydrogen bonding. Aromatic π-π stacking inter-actions are also observed between adjacent non-benzenoid aromatic tropolone rings.
