Abstract

^119mSn Mossbauer, ¹¹⁹Sn-¹ H three-bond nmr coupling constants, and Sn 3d_5/2 ESCA electron binding energy data for the compounds (t-C₄H₉)₂SnM(CO)_x. B, where for M = Fe, x = 4 and B = DMSO and pyridine and for M = Cr, x = 5 and B = THF, DMSO, and pyridine, favor a tin(IV) formulation. The Mossbauer QS values for M = Cr compounds (3. 4-4. 1 mm/sec) are the largest thus far recorded for four-coordinated organotin compounds. Explanations based upon ylide structures are proposed.
