(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.

Project description:The title mol-ecule, C(25)H(22)F(6)N(2)O(3), adopts an open conformation whereby the quinoline and carboxyl-ate ester groups are orientated in opposite directions but to the same side of the piperidine ring so that the mol-ecule has an approximate U-shape. The piperidine ring adopts a distorted boat conformation. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R(2) (2)(14) loops.

Project description:The asymmetric unit of the title salt solvate, C(17)H(17)F(6)N(2)O(+)·C(7)H(5)N(2)O(4) (-)·1.5H(2)O, comprises a piperidin-1-ium cation, a 3-amino-5-nitro-benzoate anion, and three fractionally occupied [i.e. 0.414?(3), 0.627?(6) and 0.459?(5)] disordered water mol-ecules of solvation. The cation has an L shape with a C-C-C-C torsion angle of -102.9?(3)° for the atoms linking the quinolinyl group to the rest of the cation. In the anion, the carboxyl-ate and nitro groups are essentially coplanar with the benzene ring [O-C-C-C torsion angle = 179.7?(2)° and O-N-C-C torsion angle = -3.9?(3)°]. In the crystal, extensive O-H?O, O-H?F and N-H?·O hydrogen bonding leads to the formation of a layer in the ab plane.
