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.
