Synthesis and Characterization of Divalent Samarium and Thulium N,N-Dimethylaminodiboranates
Abstract
Here, the syntheses and molecular structures of new SmII and TmIIN,N-dimethylaminodiboranate (DMADB) complexes are described. Treating SmI2(THF)2 with Na(H3BNMe2BH3) in THF results in the formation of Sm(H3BNMe2BH3)2(THF)3 (1), which can be readily converted to Sm(H3BNMe2BH3)2(DME)2 (DME = 1,2-dimethoxyethane) or Sm(H3BNMe2BH3)2(diglyme) by exchange with the corresponding ether. We also show that Sm(H3BNMe2BH3)2(THF)3 can be prepared by reduction of the SmIII compound Sm(H3BNMe2BH3)3(THF) with KC8 and that addition of 18-crown-6 to this reaction mixture results in the formation of the SmII compound Sm(H3BNMe2BH3)2(18-crown-6). In a similar fashion, two new TmII complexes have been synthesized: treatment of TmI2 in THF with Na(H3BNMe2BH3) results in the formation of Tm(H3BNMe2BH3)2(THF)2 and Tm(H3BNMe2BH3)2(THF)3, which form a cocrystal. IR data and elemental analyses are reported for all the new compounds, as are their crystal structures. 1H and 11B NMR data are provided where available.
