NaH3B-mu2-S(B2H5)! 1 is produced by the reaction between NaSH and THF
.BH3, under dehydrogenation. 1 is also formed as the first B-11-NMR-sp
ectroscopically detectable reaction product by the reaction between an
hydrous Na2S and THF.BH3. Adducts of BH3 with the S2- ion are not dete
ctable in THF. The anion S(BH3)4!2- can however be obtained, by the a
ddition of NaBH4 to 1 in diglyme or triglyme respectively: Na.Triglym
e!2S(BH3)4! 2. 2 crystallizes in the monoclinic space group P2(1)/n (
Nr. 14). Structural data of 1 and 2 have been calculated by SCF method
s. The anion of 2 may be viewed either as an adduct of B2H6 with S2-,
or as a bridge substituted thia derivative Of B2H7-; furthermore the a
nion of 2 is isoelectronic and isostructural with the SO42- ion.
