The
synthesis of the bis(crown ether)-substituted organostannanes
X2Sn(CH2-[16]-crown-5)2 (3, X = I; 4, X = Br; 5, X = Cl; 6, X = F) and X2Sn(CH2-[13]-crown-4)2 (10, X = I; 11, X = Br; 12, X = F) is reported. The compounds have been characterized by 1H, 13C, 19F, and 119Sn NMR
spectroscopy, elemental
analyses, and electrospray ionization mass spectrometry (ESI-MS).
Single-crystal X-ray diffraction analyses reveal a distorted-octahedral cis,cis,trans configuration
of the tin atoms in compounds 4–6 and 10–12 as a result of intramolecular
O→Sn coordination. The ability of the host molecules to form
mono- and ditopic complexes with various halide salts in different
solvents, including water, has been investigated by NMR spectroscopy
and ESI-MS.
