Structure and properties of double-C,N-chelated tri- and diorganotin(IV) halides

“…The NMR study for compound 5, including the study of adduct of 5 with pyridine, has already been done. 6 The 1 H and 119 Sn NMR spectra reveal only minimal changes in chemical shifts going from toluene 6 to chloroform (see Experimental section).…”

“…6 Compound 5 has been made to confront the structure and behaviour of diorganotin compounds bearing one and two possible chelating ligands. The structure of these compounds was studied by diffraction methods (1, 2, 4, 5) and NMR techniques.…”

Oxidative-addition reactions of molecular diiodine and dibromine to divalent organotin compounds. Crystal structures of bis[8-(dimethylamino)-1-naphthyl]tin(IV) dibromide and {2,6-[bis(dimethylamino)methyl]phenyl}- (4-tolyl)tin(IV) diodide

“…In previous work we have shown that the reaction of arylcopper compounds with tin tetrahalides or diorganotin dihalides affords triorganotin halides [13] and diorganotin dihalides [14] selectively and in high yield.…”

Solid‐State Structure and Behaviour in Solution of Hypervalent Organotin(IV) Derivatives Containing 2‐(Me2NCH2)C6H4 Moieties

“…Several symmetric diorganotin(IV) dihalides containing 2-(Me 2 NCH 2 )C 6 H 4 groups [1][2][3][4][5][6][7] or related organic ligands [1,3,[8][9][10][11][12] have been investigated so far both in solution and in the solid state. Single-crystal X-ray diffraction studies have revealed that strong intramolecular NǞSn interactions are established by both nitrogen atoms of a molecular unit.…”

“…All [2-(Me 2 NCH 2 )C 6 H 4 ] 2 SnX 2 (X = F, Cl, Br, I) are monomeric, with hypervalent octahedral cis-X 2 -cis-N 2 -trans-C 2 configurations (Scheme 1, A). [4][5][6][7] In contrast, the related [Me 2 N(CH 2 1, B). [10,12] The use of an organic ligand with a potential for only one intramolecular NǞSn interaction resulted in trigonal bipyramidal (C,N,C)SnX 2 configurations, e.g.…”
