Isopropyl 2,2-bis­(4-bromo­phen­yl)-2-hy­droxy­acetate

The title compound, C(17)H(16)Br(2)O(3), which is a restricted commercial acaricide (common name bromo­propyl­ate), has two independent and conformationally similar mol­ecules 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 mol­ecules 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. Inter­molecular O—H⋯O hydrogen-bonding inter­actions involving the hy­droxy groups and carboxyl O-atom acceptors give separate centrosymmetric homodimers through cyclic hydrogen-bonding motifs [graph set R (2) (2)(10)].
