Abstract

The reaction of 2,4,6-Me₃C₆H₂PHNa with Sn(NMe₂)₂ (3 : 1 equivalents, respectively) results in the formation of the unusual [{2,4,6-Me₃C₆H₂P}{4,6-Me₂C₆H₂(2-CH₂)P}Sn]³⁻ stannate trianion in the heterometallic cage [{2,4,6-Me₃C₆H₂P}{4,6-Me₂C₆H₂(2-CH₂)P}Sn]Na₃·2TMEDA]₄ (1), in which unprecedented ortho-Me deprotonation of a [2,4,6-Me₃C₆H₂P]²⁻ ligand has occurred.
