“…preparing B,H,, B,H,Br, and B5H9,51 and reasons given for assigning B,N,H, a str~icture-nTH<BH.NH>BH-recalling BH*NH that of benzene.52 The compounds BBr,,HCN and BBr,,AgCN have becri prepared.53 A convenient method for preparing anhydrous aluminium bromide has been given.54 Aluminium chloride forms a white compound AlCl,,BHCN with hydrogen cyanide.55 Tensimetric and other measurements have been made on the numerous ammines of aluminium chloride, bromide, and iodide.56 The mono-ammines in all cases are unimolecular non-ionic compounds [AlX,,NH,]. Alkali or alkaline-earth permutites become blue when treated with alkali sulphide or polysulphide solution in presence of air.…”
