The first authenticated example of triorganotin(IV) perchlorate complexes of some heterocyclic bases
摘要:
A convenient method is reported for the synthesis of some novel complexes of composition (R3SnL2) ClO4 where L represents pyridine, gamma-picoline, 2,2'-bipyridine and 1,10-phenanthroline; and R = nBu or Ph. All of the new ionic complexes have been characterized by elemental analysis, molar conductance, infrared, multinuclear nuclear magnetic resonance (H-1, C-13 and Sn-119) and Sn-119 Mossbauer spectroscopies. The complexes of composition (R3SnL2)ClO4 exist both in solution and in the solid state with trans-trigonal bipyramidal structure where the R-groups occupy the equatorial positions while the ligands are in the axial position.

Cationic single-bridged trinuclear cyano complexes are obtained by treating trihydrocarbyltin perchlorate (SnR3O2ClO2) (R alkyl or aryl) with neutral transitionmetal monocyanides, whereas treatment with the corresponding neutral or anionic transitionmetal polycyanides gives neutral single-bridged polymeric cyano compounds. In every case the tin atoms are pentacoordinated with the three R groups
阳离子单桥三核氰基配合物是通过用中性过渡金属单氰化物处理高氯酸三烃基锡(SnR 3 O 2 ClO 2)(R烷基或芳基)而获得的,而用相应的中性或阴离子过渡金属多氰化物处理则得到中性单桥聚合氰基化合物。在每种情况下,锡原子在三角双锥体的轴向位置上与赤道中的三个R基团和两个CN基团(或分别为一个CN和一个OClO 3基团)五配位。
