B2Cl4 and PCl3 in a vacuum were heated at 300.degree. for 12 h to give closo-3,4,5,6-tetrachloro-1,2-diphosphahexaborane(4) (I). I was characterized by 11B and 31P NMR and mass spectra. I is orthorhombic, space group Pbna, with a 600.2(2), b 1240.1(3), c 2270.6(8) pm, Z = 8, d.(calcd.) = 1.941 g cm-3, R = 0.073 for 1825 reflections with F > 3.sigma.(F).
