Abstract X‐ray diffraction data and NMR spectra of diperchloratotetraphenylporphinatotin(IV), Sn(tpp)(ClO 4 ) 2 provide evidence for a monodentate perchlorato group coordinated to the Sn(IV) atom. The molecule Sn(tpp)(ClO 4 ) 2 displays an octahedral coordination geometry for the tin atom and its crystal belongs to the monoclinic space group P2 1 /n with a = 11.241(3), b = 14.644(3), c = 12.173(3) Å,β = 111.18(2)°, and Z = 2. The structure was solved by direct method, 3996 unique reflections having I > 3σ(I) measured with an automated diffractometer were used to refine the crystal structure to a conventional R factor 0.0431. The tin(IV) ion is centered on a planar tpp moiety. The geometry at the octahedral coordination centre of the Sn(tpp) (ClO 4 ) 2 molecule has Sn‐O(perchlorate) = 2.181 Å and Sn‐N = 2.073 Å.
