cze	Structure of N,C,N chelated Organotin(IV) Fluorides	The set of starting tri-, di- and monoorganotin(IV) halides containing IV,C,N-chelating ligand (L-NCN = {1,3-[(CH3)(2)NCH2](2)C6H3}(-)) has been prepared (1-5) and two compounds structurally characterized ([(LPh2Sn)-Ph-NCN]I-+(3)- (1c), (LSnBr3)-Sn-NCN (5)) in the solid state. These compounds were reacted with KF with 18-crown-6, NH4F or L(CN)nBu(2)SnF to give derivatives containing fluorine atom(s). Triorganotin(IV) fluorides (LMe2SnF)-Me-NCN (2a) and L(NCN)nBu(2)SnF (3a) revealed monomeric structural arrangement with covalent Sn-F bond both in the coordinating and non-coordinating solvents, except the behaviour of 3a that was ionized in the methanol solution at low temperature. The products of fluorination of (LSnPhCl2)-Sn-NCN (4) and 5 were described by NMR in solution as the ionic hypervalent fluorostannates or the oligomeric species reacting with chloroform, methanol or moisture to zwitterionic monomeric stannate L-NCN(H)+SnF4-(5c), which was confirmed by XRD analysis in the solid state.
