{Tris[N-(salicylidene)-2-aminoethyl]amine}tin(IV) Iodide Acetonitrile Solvate

The crystal structure of the title compound, [Sn(C₂₇H₂₇N₄O₃)]I.0.5CH₃CN, involves two almost identical complex cations in the asymmetric unit. These cations contain Sn atoms in a pseudo-octahedral environment with facial coordination of the azomethine N and the phenolate O atoms. The average Sn-O and Sn-N bond lengths are 2.048 (4) and 2.192 (5) Å, respectively, while the apical N atom in the ligand is considered to be non-bonded at an average distance of 2.687 (5) Å from the Sn atom.
