Notes:
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.
