Research on the failure reasons of the cooling tube were carried out by means of macroexamination, thickness measurement, X ray diffraction, optical microscopy and chemical analysis.
The crystal structure has been determined by X ray single crystal diffraction, showing a distorted trigonal bipyramidal configuration with five coordination for the central tin atom.
