The syntheses of the organotin‐substituted crown ethers m ‐(Ph 2 XSnCH 2 CH 2 )‐15‐benzocrown‐5 ( 2 , X = Ph; 3 , X = I; 4 , X = Cl; 5 , X = NCS) and the salt [ m ‐(Ph 3 SnCH 2 CH 2 )‐15‐benzocrown‐5 · Na] + SCN – ( 2a ) are reported. Compounds 2a and 4 (as its aqua complex 4· H 2 O) are characterized by single‐crystal X‐ray diffraction sudies. Multinuclear NMR spectroscopy and electrospray mass spectrometry reveal the triorganotin chloride 4 to be a ditopic host towards sodium rhodanide. This statement is further supported by the ability of compound 4 to transport sodium rhodanide through an organic membrane. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
