Abstract

In the crystal structure of the title compound, C(7)H(6)BFO(2), a broad-spectrum anti-fungal drug (AN2690), the planar [maximum deviation 0.035 (1) Å] mol-ecules form centrosymmetric R(2) (2)(8) dimers via strong O-H⋯O hydrogen bonds. The dimers are arranged into layers by weak inter-molecular C-H⋯O and C-H⋯F hydrogen bonds. The symmetry of this two-dimensional supra-molecular assembly can be described by the layer group p and topologically classified as a simple uninodal four-connected two-dimensional network of a (4.4.4.4.6.6) topology. Further weak C-H⋯O inter-actions build up the three-dimensional structure.
