Palladium forms a range of zerovalent complexes with the formula PdL 4, PdL 3 and PdL 2. For example, reduction of a mixture of PdCl 2 (PPh 3) 2 and PPh 3 gives tetrakis (triphenylphosphine)palladium (0): [17] 2 PdCl 2 (PPh 3) 2 + 4 PPh 3 + 5 N 2 H 4 → 2 Pd (PPh 3) 4 + N 2 + 4 N 2 H 5+ Cl − See more Palladium is a chemical element with the symbol Pd and atomic number 46.
