- 中文摘要: Mossbauer isomer shifts of /sup 119/Sn in a series of complexes K/sub 2/Sn(OH)/sub 6-m/F/sub m/ observed at 78K were -0.05, -0.05, -0.24, -0.27 and -0.40mms/sup -1/, respectively, for m=0, 2, 4, 5 and 6. These IS values were linearly related to both m and .chibar./sub p/ (the average Pauling electronegativity of the ligands): IS=-0.06m=4.39-1.19.chibar./sub p/. The IS-.chibar./sub p/ straight line was compatible within experimental error with the one reported by Parish and Rowbotham for the hexahalogenostannate complexes SnX/sub 4/Y/sub 2//sup 2-/, namely, IS=4.27-1.16.chibar./sub p/. The revised IS-.chibar./sub p/ straight line including both series of complexes could be expressed by the equation IS=4.22-1.14.chibar./sub p/. Quadrupole splittings observed in the complexes of m=2, 4 and 5 were 1.16, 0.80 and 0.73mms/sup -1/, respectively. They were linearly related to both m and Xp:QS=1.44-0.15m=12.44-2.97.chibar./sub p/.
