Abstract
The SnIV atom in the title compound, [Sn(CH3)2(C17H14N2O3)], is five-coordinated within a C2N2O donor set provided by the N,N,O-tridentate ligand and two methyl groups. The resultant coordination geometry is intermediate between trigonal-bipyramidal and square-pyramidal. In the crystal, supramolecular zigzag chains propagating along the c- axis direction are mediated by O—H⋯O hydrogen bonds, and weak C—H⋯π interactions consolidate the packing.

The resultant coordination geometry is intermediate between trigonal-bipyramidal and square-pyramidal
C2NO2 donor set defines a coordination geometry intermediate between square pyramidal and trigonal bipyramidal geometry. This is quantified by the value of τ = 0.51 which compare to the τ values of 0.0 and 1.0 for ideal square pyramidal and trigonal bipyramidal geometries, respectively (Addison et al, 1984)
