Cationic Cryptand Complexes of Tin(II)
A series of cationic cryptand complexes of tin(II), [Cryptand[2.2.2]SnX][SnX3] (10, X = Cl; 11, X = Br; 12, X = I) and [Cryptand[2.2.2]Sn][OTf](2) (13), were synthesized by the addition of cryptand[2.2.2] to a solution of either tin(II) chloride, iodide, or trifluoromethanesulfonate. The complexes could also be synthesized by the addition of the appropriate trimethylsilyl halide (or pseudohalide) reagent to a solution of tin(II) chloride and cryptand[2.2.2]. The complexes were characterized using a variety of techniques including NMR, Raman, and temperature-dependent Mossbauer spectroscopy; mass spectrometry, and X-ray diffraction.
