    Description / Table of Contents: Ionic Crown Ether Complexes of Tin(II) and Tin(IV): [Sn(15-Crown-5)][SnCl6] and [SnCl3(18-Crown-6)]2[Sn2Cl10]; Syntheses, IR Spectra, and 119Sn-Mössbauer Spectra[Sn(15-crown-5)][SnCl6] (1,) has been prepared by the reaction of SnCl2, SnCl4, and 15-crown-5 in the molar ratio of 1 : 1 : 1 in acetonitrile solution, forming a white insoluble crystal powder. [SnCl3(18-crown-6)]2[Sn2Cl10] (2,) as well as [SnCl3(18-crown-6)][BiCl4] · CH3CN (3,) are prepared by the reaction of SnCl4 with 18-crown-6 (molar ratio 2 : 1), and of SnCl4, 18-crown-6, and BiCl3 (molar ratio 1 : 1 : 1), respectively. According to IR-spectroscopy and 119Sn-Mössbauer-spectroscopy 1-3, have ionic structures; the cation of 1, being polymeric via a sandwich-like structure.
    Notes: [Sn(15-Krone-5)] [SnCl6] (1,) entsteht als schwerlösliches weißes Kristallpulver aus SnCl2, SnCl4 und 15-Krone-5 im Molverhältnis 1 : 1 : 1 in Acetonitrillösung, während [SnCl3(18-Krone-6)]2[Sn2Cl10] (2,) aus SnCl4 und 18-Krone-6 im Molverhältnis 2 : 1 und [SnCl3(18-Krone-6)] [BiCl4] · CH3CN (3,) aus SnCl4, 18-Krone-6 und BiCl3 im Molverhältnis 1 : 1 : 1 gebildet werden. Aus den IR- und den 119Sn-Mößbauer-Spektren wird auf ionische Strukturen geschlossen; das Kation von 1, besitzt eine polymere Struktur, in der das Sn2+ -Ion über (15-Krone-5)-Moleküle sandwichartig gestapelt ist.
