Chlorid palladnatý je sloučenina s chemickým vzorcem PdCl2. PdCl2 je častá výchozí látka pro přípravu palladiových katalyzátorů v organické syntéze.

Struktura

PdCl2 krystalizuje ve dvou polymorfních formách. V obou formách je palladium čtvercově planárně koordinováno atomy chloru. Atomy Pd(II) jsou spojeny můstkovými μ2-chloridovými atomy. Polymerní α-forma PdCl2 je tvořena nekonečnými řetězci.[2] Molekulární β-forma PdCl2 je tvořena oktaedrickými klastry obsahujícími šest atomů palladia.[3]
