Abstract

The oxidative addition of alkyl iodides to the tin(II) complex of the 6,8,15,17-tetramethyl-5,9,14,18-tetraazadibenzo[14]annulene dianion, Sn(tmtaa), in THF produced cationic, five-co-ordinate complexes [Sn(tmtaa)(R)]I, where R = Me, Et, n-Pr or n-Bu. Diiodomethane added to two equivalents of Sn(tmtaa) to give the CH2 bridged dication [{Sn(tmtaa)}2(µ-CH2)]I2. The new alkyl complexes are all air stable in solution and the solid state. Two of the complexes, [Sn(tmtaa)Me]I·2CHCl3 and [{Sn(tmtaa)}2(µ-CH2)]I2·2CHCl3·LiI·3H2O, have been characterised by single crystal X-ray diffraction studies, which confirms the five-co-ordinate geometry of the cations.
