| Abstract: | Heats of solution of the tin(II) halides in the donor solvents dimethylsulfoxide and N,N-dimethylformamide have been found to be exothermic, decreasing in the order SnI2 > SnBr2 > SnCl2 > SnF2. The magnitude of the heats of solution in dimethylformamide were substantially greater than those in dimethylsulfoxide. The heats of reaction of the tin(II) halides in dimethylsulfoxide solution with liquid triethylamine were also measured and found to be exothermic but smaller in magnitude than the solution heats. The same order of acceptor strengths were observed although the differences between the halides were smaller. |
