- 中文摘要: X-ray diffraction data and NMR spectra of diperchloratotetraphenylporphinatotin(IV), Sn(tpp)(ClO/sub 4/)/sub 2/, provide evidence for a monodentate perchlorato group coordinated to the Sn(IV) atom. The molecule Sn(tpp)(ClO/sub 4/)/sub 2/ displays an octahedral coordination geometry for the tin atom and its crystal belongs to the monoclinic space group P2/sub 1//n with a=11.241(3), b=14.644(3), c=12.173(3).ANG.,.beta.=111.18(2).degree., and Z=2. The structure was solved by direct method, 3996 unique reflections having I>3.sigma.(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/sub 4/)/sub 2/ molecule has Sn-O(perchlorate)=2.181.ANG. and Sn-N=2.073.ANG..
