摘要：

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)(mu-CH2)]I-2. The new alkyl complexes are all air stable in solution and the solid state. Two of the complexes, [Sn(tmtaa)Me]I . 2CHCl(3) and [{Sn(tmtaa)}(2)(mu-CH2)]I-2. 2CHCl(3). LiI . 3H(2)O, have been characterised by single crystal X-ray diffraction studies, which confirms the five-co-ordinate geometry of the cations.
