Abstract
N-(3-hydroxypyridine-2-yl)-5-hydroxysalicylideneimine(HOC 6H 3OHCHNC 5H 3NOH) ( 1) and its dimethyltin(IV) complex (Me 2Sn(OC 6H 3OHCHNC 5H 3NO)) ( 2) were prepared and characterized by 1H-NMR, IR, mass spectroscopy and single crystal X-ray diffraction method. The complex ( 2) crystallizes in the space group C 2/ c with cell dimensions a=20.841(2), b=10.646(2), c=13.206(2) Å, β=105.95(1)° with Z=8, V=2817.3(6) Å 3. Molecular structure has been determined by standard methods and refined by full-matrix least squares (on F 2) to R value of 0.036. The studied tin(IV) complex exhibits the strongly distorted square-pyramidal geometry around tin atom. In the solid state, each distorted square-pyramidal Me 2Sn(OC 6H 3OHCHNC 5H 3NO) unit is connected to the others via dual use of hydrogen bonds and π–π interactions. The tautomeric effect of ligand was discussed besides the coordination geometry of the complex ( 2).
