ハロゲン化スズ(II)の錯化合物のメスバウア研究

Mossbauer spectra of <119>^Sn were observed in tin (II) chloride, bromide and their complexes of the types MSnX^3・H_20 and M_2SnX_4・H_20, where M = NH_4, K or Cs, and X = Cl or Br. All of the complexes exhibited small quadrupole splittings. In comparison with the parent halides SnX_2, the complex chlorides have smaller isomer shifts, whereas this is not the case for the complex bromides. The isomer shift was related to the strength of the ligand field, and the decrease in the isomer shift was interpreted by s-p mixing due to the field stabilization.
