, crystallizes with one and a half independent molecules in the asymmetric unit, with the half-molecule being completed by crystallographic inversion symmetry. Both independent molecules are almost planar, with the non-H atoms exhibiting r.m.s. deviations from the least-squares molecular plane of 0.175 and 0.118 Å, respectively.
