Synthesis and Characterization of N-[2-P(i-Pr)(2)-4-methylphenyl](2)(-) (PNP) Pincer Tin(IV) and Tin(II) Complexes
N-[2-P(i-Pr)(2)-4-methylphenyl](2)(-) (PNP) pincer complexes of tin(IV) and tin(II), [(PNP)SnCl3] (2) and [(PNP)SnN(SiMe3)(2)] (3), respectively, were prepared and characterized by X-ray diffraction, solution and solid state NMR spectroscopy, and Sn-119 Mossbauer spectroscopy. Furthermore, Sn-119 cross polarization magic angle spinning NMR spectroscopic data of [Sn(NMe2)(2)](2) are reported. Compound 2 is surprisingly stable toward air, but attempts to substitute chloride ligands caused decomposition.
