Tin-119 Miissbuuer spectra show that the cationic oxidation states and crystal structures of some mived oxide catalysts remain unaltered by the adsorption of acidic or basic molecules. Reaction of the oxides with either hydrogen or butenes gives reduced catalysts in which the retention of the tin at

Tin-antimony oxides of the type SnJb,O2 (x = 0.01-0.10) when calcined at 873K form solid solutions in which the Miissbauer parameters steadily depart from those of stannic oxide but provide no evidence for the formation of localised tin(U). Esr measurements indicate the presence of a spin free surfa
This paper reports the results of 119 Sn Mo ¨ssbauer Spectroscopy of residues from the pyrolysis of Sn 3 O 3 Bu 6 (1) and Sn 4 O 6 Bu 4 (2) (Bu ¼ n-butyl) in air, O 2 , and N 2 . The isomer shift and quadrupole splitting parameters of the samples allowed the identification of the tin oxidation state
