The self-assembled reaction of 2-hydroxynicotinic acid, KOH and tri-n-butyltin chloride in CH3OH and H2O (V/V = 5:1) under solvothermal condition (150 degrees C) affords a novel mixed tri- and dibutyltin macrocyclic complex 1. Characterization of the complex 1 was achieved using elemental analysis, IR, NMR (H-1, C-13 and Sn-119) spectroscopy, TGA and X-ray crystallography diffraction analysis. X-ray data revealed that it is an unusual 16-membered macrocycle containing eight tin atoms, and they can be divided into four sorts by the distinct environments, the endocyclic tin atoms are best described as five- and six-coordinate and the exocyclic tin atoms as five-coordinate. Furthermore, a 2D corrugated sheet is formed by intermolecular C-H center dot center dot center dot Cl, O-H center dot center dot center dot N and O-H center dot center dot center dot O weak interactions.
