A solution of PdCl2 (89.0 mg, 0.5 mmol) in 5 ml water was
added to 10 ml of stirring aqueous solution containing 425 mg
(1 mmol) of (MetH)2(dipic). The reaction mixture was concentrated
by slow evaporation and a light yellow solution was
achieved. After 1 h, 140 mg crystalline PdII complex in 70% yield
was obtained.
