Abstract A series of compounds Na3[Fe(CN)5RNH2] · nH2O where R = -H, -CH3, -C2H5, n-C3H7, n-C4H9 and -CH2C6H5 and RNH2 = C5H5N have been studied by Mössbauer spectroscopy. Quadrupole splitting (⊿EQ) values vary in a limited range (0.68-0.80 mm/sec) indicating only small distortions in the octahedral geometry of the compounds with the substitution of various amino groups. Isomer shift (δ) values remain almost constant suggesting that s-electron density is not affected by substitution.

The Sn1−xSbxO2 system has been studied by means of 119Sn and 121Sb Mössbauer spectroscopy. The presence of an unresolved quadrupole splitting in SnO2 is confirmed. The data show that the oxidation states of the tin and antimony are IV and V, respectively. The conduction electrons resulting from Sb substitution are distributed over the entire lattice. As the Sb content increases, the 119Sn isomer shift and s electron density at the Sn nucleus also increase, as expected for a conduction band composed largely of Sn 5s orbitals.
