Bis(acetylacetonato)dichlorotin(IV) is synthesized from the aqueous solutions of tin(IV) chloride and acetylacetone followed by vacuum drying at room temperature. DTA/TGA, FTIR, UV-VIS, X-ray powder and single crystal, mass spectra and elemental analysis are performed to characterize the product. X-ray powder diffraction suggests that the sample may contain some impurities such as SnO, SnO₂ and Sn₂О₃ while the mass spectra indicates the existence of Sn(acac)₄, which is arguable due to the steric effect. Single crystal investigation reveals that the product synthesized in aqueous solution is Sn(acac)₂Cl₂, crystallized in monoclinic system in space group C2/c with unit cell constants a=13.983(2), b=7.8928(8), c=13.7889(19) Å and β =107.601(11)°, whose volume is 1.43 % smaller than the one synthesized in dry toluene.
