The compound B8F12, prepared by disproportionation of of F2BBFBF2, has been characterised. It is believed to be a structural analogue of diborane. It has been treated with electron-pair donors to give complexes (BF2)3BL (L = CO, PF3, PCl3, PH3, AsH3, and SMe2). Related complexes have been made from SiCl2 or SiF2 and diboron tetrahalides in the presence of CO or PF3, and the compounds (SiCl3)2(BCl2)BCO and (SiCl3)2(BF2)BPF3 have been characterised.
