Variable-temperature 119Sn Mössbauer spectroscopic (VTMS) data for six tin phthalocyanine (pc) derivatives have been collected in order to ascertain the restrictions imposed by the macrocyclic ring on the vibrational motion of the tin atom. Thermal condensation of [(t-Bu)4pc]Sn(OH)2 yields the co-facially stacked polymer {[(t-Bu)4pc]SnO}n which can be distinguished in the VTMS experiment by the enhanced rigidity of its structure.
