Mössbauer spectroscopic studies of the coordination polymers [A(Me3Sn)3Fe(CN)6]x(A = Me3Sn+, Et4N+, Cp2Fe+ etc.)

Inorganic Polymer Characterization

“…The coordination polymers f[ CH 3 3 Sn IV ] 3 Fe III CN 6 g n and fA[ CH 3 3 Sn IV ] 3 Fe II CN 6 g n where A D CH 3 3 Sn C , C 2 H 5 4 N C , C 5 H 5 2 Fe C , etc., have been studied by both iron-57 and tin-119 Mössbauer spectroscopy (80). The tin-119 Mössbauer spectral parameters for the polymers indicate that all of the tin atoms in the polymers are coordinated to three methyl groups (as expected) and two cyano groups consistent with the tin(IV) centers having trigonal bipyramidal structures.…”
