title: Isopropyl 2,2-bis-(4-bromo-phen-yl)-2-hy-droxy-acetate.
abstract: The title compound, C17H16Br2O3, which is a restricted commercial acaricide (common name bromo-propyl-ate), has two independent and conformationally similar mol-ecules in the asymmetric unit [dihedral angles between the planes of the two phenyl rings = 68.7 (4) and 77.4 (5)°]. The C atoms of the isopropyl group of one of the mol-ecules are disordered over two sites with occupancies of 0.638 (16) and 0.362 (16). Minor non-merohedral twinning was also present in the crystal. Inter-molecular O-H⋯O hydrogen-bonding inter-actions involving the hy-droxy groups and carboxyl O-atom acceptors give separate centrosymmetric homodimers through cyclic hydrogen-bonding motifs [graph set R2(2)(10)].
