1,10-phenanthroline (phen), 2,2'-bipyridyl (bipy), pyridine (py) and 4-picoline (4-pic) complexes of dibutyltindichloride (Bu2SnCI2) and dimethyltindichloride (Me2SnClz) were synthesized. The complexes were characterized with the help of elemental analyses, IR spectra and thermal analyses. The complexes were found to have the compositions 2(4-pic)]'H20. All these complex compounds appeared to posses octahedral structures. Thermodynamic parameters, such as activation energy E* enthalpy change AH and entropy change AS, for the dehydration and sublimation of the complexes were evaluated using some standard methods.
