Abstract

The preparation and structures of three diborane(4) compounds are described. The compound B₂(3,4-S₂C₄H₂-1-S)₂ [2,2'-bi(1,3,5,2-trithiaborapentalene), C₈H₄B₂S₆] is planar and lies at a crystallographic inversion centre. The amine adducts [B₂(C₃S₅)₂(NHMe₂)₂] [2,2'-bis(dimethylamino)-2,2'-bi(1,3,4,6,2-tetrathiaborapentalene-5-thione), C₁₀H₁₄B₂N₂S₁₀] and [B₂(1,2-S₂C₂H₄)₂(NHMe₂)₂]·0.33CH₂Cl₂ [1,2-bis(di-methylamino)-1,1:2,2-bis(dimethylenedithioxy)diborane(4) dichloromethane solvate, C₈H₂₂B₂N₂S₄·0.33CH₂Cl₂] contain dimethylamine ligands bound to each boron in an anti conformation about the B-B bond, with tetrahedral geometry at the B atoms. The crystal structures display a number of S...S interactions, which appear to dictate the packing arrangements.
