摘要：

The syntheses of the organotin-substituted crown ethers Ph2XSnCH2[19]-crown-6 (1, X = Ph; 2, X = Br; 3, X = 1; 4, X = Cl; 5, X = F; 6, X = SCN) and Ph2XSnCH2Sn(Y)PhCH2-[19]-crown-6 (7, X = Y = Ph; 8, X = Ph, Y = 1; 9, X = Y = 1) and of the ditopic complexes 5 . KF, 6 . KSCN, and 9 . KF are reported. These compounds are characterized by elemental analyses, H-1, C-13, and Sn-119 NMR spectroscopies, electrospray mass spectrometry, and in the cases of 1-4, 8, 9 . H2O, and 9 . KF also by single-crystal X-ray diffraction studies. The coordination geometry about the tin atoms in compounds I and 8 (Sn2) is distorted tetrahedral, whereas it is trigonal bipyramidal for the tin atoms in compounds 2, 3, 4, 8 (Sn1), 9 . H2O, and 9 . KF.
