Zinc hydride cation [ZnH](+) supported by TMPDA (TMPDA = N,N,N ',N '-tetramethylpropane-1,3-diamine)

Résumé

Selective protonolysis of polymeric zinc dihydride [ZnH2](n) by the conjugate acid of the chelating N,N-donor TMPDA (TMPDA = N,N,N',N'-tetramethylpropane-1,3-diamine) [(TMPDA)H)][B(3,5-(CF3)(2)-C6H3)(4)] in THF gave the molecular zinc hydride cation [(TMPDA)ZnH(thf)][B(3,5-(CF3)(2)-C6H3)(4)] that is stable in THF but crystallized as the dimer [(TMPDA)(2)Zn-2(mu-H)(2)][B(3,5-(CF3)(2)-C6H3)(4)](2) from CH2Cl2/n-pentane. The protonolysis with half equivalent of the conjugate acid or the reaction of isolated [(TMPDA)ZnH (thf)][B(3,5-(CF3)(2)-C6H3)(4)] with one equivalent of zinc dihydride in THF gave the molecular dizinc trihydride cation [(TMPDA)(2)Zn2H2(mu-H)][B(3,5-(CF3)(2)-C6H3)(4)].
