In the title compound, [PdCl2(C6H6N2O2)2], the PdII atom is coordinated in a distorted square-planar geometry by two N atoms from two 4-nitroaniline ligands and two Cl atoms in a trans arrangement. Intermolecular N-HCl hydrogen bonds involving the amino groups and chloride anions lead to a chain along . These chains are further self-assembled into a three-dimensional network through N-HO and N-HCl hydrogen bonds.
