• The <SUP>119</SUP>Sn Mössbauer effect was studied in tetracarbonylcobalt derivatives of tin(IV) halides, X<I><SUB>n</SUB></I>Sn[Co-(CO)<SUB>4</SUB>]<SUB>4−<I>n</I></SUB>, where X=Cl, Br or I, and <I>n</I>=0∼4. The isomer shift in each halogen series increased as the halogen atom was successively replaced by the Co(CO)<SUB>4</SUB> group. The values of the isomer shift were between those of tin(IV) halides and XSn[Co(CO)<SUB>4</SUB>]<SUB>3</SUB> and did not change lineraly with the number of halogen atoms. The values of the quadrupole splitting were smaller than those of the corresponding organotin halides, X<I><SUB>n</SUB></I>SnR<SUB>4−<I>n</I></SUB>, and attained their maximum at dihalides. From the Mössbauer parameters, the chemical bonds in the compounds, especially the Sn-Co bond, were discussed.
