Abstract
The iso-tetraphosphane P((PBu2)-Bu-t)(3) (1) was obtained by irradiating (B u2P)-Bu-t-P=P(Me)Bu-t(2) (3). 1 forms hexagonal crystals (space group P6(3) /m) with a=1005,63(8), c=1621,4(2) pm, Z=2. The P((PBu2)-Bu-t)(3) molecules are arranged in a hexagonally close packed lattice. The four P atoms in ea ch molecule are coplanar with P-P bond distances 219.08(4) pm and P-P-P ang les 120 degrees. The observed planar geometry is in accordance with nb init io calculations.
