✦ Synopsis
The bis(butanoato)zinc (II) and pcoxohexa-F-butanoatotetrazinc(I1) complexes of n-and isobutanoic acids G3KH,(CH,)2COO12, Zn40KM3(CH2)2COO16, ZnKCH,),CHCOOl, and Zn,O[(CH,),CHCOOl,) were prepared and their infrared spectra recorded in the solid state and in carbon tetrachloride solution. Both forms of zinc butanoates, i.e., the biskarboxylato) and 0x0 salts were found to exist as tetranuclear oxozinc carboxylates in carbon tetrachloride solution as a result of the equilibrium 4 Zn(RCOO), + Hz0 (sol. in Ccl,) f Zn,O(RCOO), + (RCOOH), The oxozinc butanoates decomposed to biskarboxylato) salts and zinc oxide during crystallization: Zn,O(RCOO)s -+ 3 Zn(RCOO)z + ZnO solution in Ccl, solid Three fundamental types of structure were distinguished and their structural and chemical changes could clearly be monitored by means of Fourier transform infrared spectroscopy.
