Abstract The new complex [Pd 2 (HPCH 2 CH 2 CH 2 PH)(H 2 PCH 2 CH 2 CH 2 PH 2) 2] Cl 2 has been prepared by treatment of Na 2 PdCl 4 with H 2 P (CH 2) 3 PH 2 in ethanol. This product has been treated with sodium perchlorate in ethanol to give the corresponding diperchlorate, which is very explosive.
