Binuclear Niobium Complex with Coordinated N-Heterocyclic Carbene

Аннотация

By the interaction of Nb(NMe₂)₅ and 1,3-(2,6-diisopropylphenyl)imidazolium (IPr·HBF₄) tetrafluoroborate a binuclear complex with coordinated N-heterocyclic carbene [(IPr)Nb(=NMe)(NMe₂)(μ-F)₂(μ-NMe₂) NbF₂(NMe₂)] (1) is obtained. The reaction of Nb(NMe₂)₅ and 1,3-(2,4,6-trimethylphenyl)imidazolium (IMes·HBF₄) tetrafluoroborate yields [(IMes)₂H][NbF₆] salt (2). The structure of the complexes is determined by single crystal X-ray diffraction.
