摘要：

The structures of the complexes [Sn(tpp)F-2] (1) and [Sn(tpp)(NO3)(2)] (2) (tpp = dianion of 5,10,15,20-tetraphenylporphyrin) have been determined by single crystal X-ray diffraction. Bond lengths in complex 1 are Sn-F 1.946(5) Angstrom and Sn-N 2.056(7) and 2.071(6) Angstrom. Complex 2 has monodentate nitrate ligands, and bond lengths Sn-O 2.113(5) Angstrom and Sn-N 2.075(5) and 2.080(5) Angstrom. A comparison of bond length and spectroscopic data for these and other [Sn(tpp)X(2)] complexes reveals that the core sizes of the complexes of O-bound ligands and [Sn(tpp)Cl-2] correlate well with the published Sn-119 NMR linewidths, and with Raman shifts for the band assigned as nu(CaCb). However, the Sn-N bond lengths of 1 are significantly shorter than those predicted by such correlations.
