title: (Z)-N'-Hy-droxy-4-(trifluoro-meth-yl)benzimidamide.
abstract: In the title compound, C(8)H(7)F(3)N(2)O, the OH and NH(2) substituents adopt a Z configuration with respect to the C=N bond. The hy-droxy-imidamide unit is almost planar (r.m.s. deviation = 0.007 Å) and subtends an angle of 26.25 (13)° with the benzene ring. The F atoms of the trifluoro-methyl substituent are disordered over two sets of sites with an occupancy ratio of 0.783 (15):0.217 (15). In the crystal, O-H⋯N hydrogen bonds form centrosymmetric dimers. Additional N-H⋯O hydrogen bonds link the dimers into zigzag chains along the b axis. Weak inter-molecular F⋯F contacts of 2.714 (5) Å are also observed.
