Аннотация:The bis(carbazolide) complex of SmII, Sm[3,6-But2-1,8-(Me3SiCºC)2Carb]2, was synthesized by the transamination reaction of Sm[N(SiMe3)2]2(THF)2 with two molar equivalents of carbazole 3,6-But2-1,8-(Me3SiCºC)2CarbH. A similar reaction of the less sterically demanding carbazole 3,6-But2-1,8-(PhCºC)2CarbH is accompanied by the oxidation of Smii to Smiii and lead to the formation of bis(carbazolide) amido complex [3,6-But2-1,8-(PhCºC)2Carb]2Sm[N(SiMe3)2]. For both Sm complexes, h2-interactions with CºC bonds, which are unconventional for Lnii and Lniii metals, were experimentally confirmed by single-crystal X-ray diffraction, IR and Raman spectroscopy along with QTAIM analysis.
