The asymmetric unit of the title compound, [Pd2(C9H12NTe)2Cl2]·0.5CH2Cl2, contains two half-molecules, each lying on a twofold rotation axis; each molecule is chiral and of the same enantiomer. This is only possible as the molecule has a hinged cis arrangement about the Pd2+ coordination spheres. For this hinged dimeric structure, the angles between the two coordination planes in each molecule are 21.59 (4) and 22.10 (4)°. This hinged cis arrangement also allows the two molecules to form pairs linked by secondary interactions between the Pd and Te atoms of an adjoining molecule, leading to a tetrameric overall structure. C-H...Cl interactions consolidate the crystal packing.
