Ligand-Directed Structural Modification of Imidotin(II) Cubanes: The Mixed Oxidation State Double-Cubanes [Sn7{2-NR}8]⋅n THF (R=Pyrimidinyl, 5-Methylpyridinyl)

Abstract

SnII/SnIV double-cubanes [Sn7(NR)8], and not as expected simple imidotin(II) cubanes of the type [{SnNR}4], are obtained from reactions of [Sn(NMe2)2] with 2-aminopyridines and -pyrimidines (the structure of the 2-imidopyrimidine derivative is shown). This ligand-dependent structural modification may indicate an as yet untapped area of electrochemistry involving other main group metal cage complexes.
