Popis:	The perchlorinated arsaboranes closo-1,2-As2B10Cl10 and As4B8C16 are formed in the co­ pyrolysis of B2C14 and AsCl3 at temperatures of 330-450°C. The icosahedral structure of closo-1,2-As2B10Cl10 is confirmed by 11B-11B-COSY-NMR spectroscopy. As4B8Cl6 is suppo­ sed to be a conjuncto-borane (As2B4Cl3)2 with two boron-boron linked As2B4Cl3 octahedra. The copyrolysis of B2Cl4 andSbCl3 or SbCl5 yields Sb2B10Cl10, and the corresponding reaction of B2Cl4 with S2Cl2 gives the icosahedral thiaborane cluster SB11Cl11 .
