چکیده
Theere are two independent mol-ecules in the asymmetric unit of the title compound, C(14)H(11)FN(2)O(2), each with a trans configuration with respect to the azo double bond. The dihedral angle between the aromatic rings is 17.21 (2)° in one mol-ecule and 19.06 (2)° in the other. Each of the independent mol-ecules has an intra-molecular O-H⋯O hydrogen bond. In the crystal, mol-ecules are stacked along [100].

The title compound, C20H21N3O, has crystallographic mirror symmetry with all non-H atoms apart from the methyl C atom of the CMe2 group lying on the mirror plane. Mol-ecules are linked into planar sheets parallel to (010) by phen-yl-azo C-H⋯N and phen-yl-ethanone C-H⋯O inter-actions. Methyl C-H⋯π inter-actions provide crosslinking between the planes.

In the title compound, [Sn(C(6)H(5))(3)(C(14)H(9)N(2)O(4))], the Sn atom has a distorted tetra-hedral geometry with one of the carboxyl-ate O atoms and the C atoms from three phenyl groups. The other carboxyl-ate O atom of the benzoate ligand inter-acts weakly with the Sn atom, with an Sn⋯O distance of 2.790 (2) Å, which causes a distortion of the tetra-hedral coordination geometry.
