Abstract
The interaction of [(ButN)2ReVI(µ-NBut)]21 with trifluoromethanesulfonic acid gave the amido complex [(ButN)(ButHN)Re(µ-NBut)2Re(NBut)2][CF3SO3], where the cation has a structure very similar to that of its manganese(VI) analogue. The interaction of 1 with silver triflate differs from the similar reaction with [(ButN)2MnVI(µ-NBut)]2 in that a silver complex {[(ButN)Re(µ-NBut)]2(µ-NBut)2Ag(µ-O3SCF3)}2 that has NBut groups bridging both rhenium and silver atoms with the latter having µ-O3SCF3 bridges is formed. A similar complex [(ButN)Re(µ-NBut)]2(µ-NBut)2Cu2(O3SCF3)2 was obtained by interaction of 1 with Cu(O3SCF3)·0.5C6H6 but this has Re(µ-NBut)Cu(O3SCF3) groups. Interaction of 1 with Al(O3SCF3)3·nCF3SO3H in CH2Cl2 gave a linear molecule (ButN)2Re(µ-NBut)2Re(NBut)(µ-OH)2Al(O3SCF3)3(H2O). The crystal structures of four compounds have been determined. An improved synthesis of 1 involving Na/Hg reduction of Re(NBut)3I was elaborated.Keywords
