In the title complex, [Pd(C16H16NO2)2]·CHCl3, the PdIIcation lies on an inversion center. One Cl atom of the CHCl3solvent molecule lies on a twofold axis and the C—H group is disordered with equal occupancies about this axis with the other Cl atom in a general position with full occupancy. The PdIIcation is four-coordinate and adopts a square-planar geometryviacoordination of the imine N and phenolic O atoms of the two bidentate Schiff base anions. The N and O atoms of these ligands are mutuallytrans. The plane of the benzene ring makes a dihedral angle of 73.52 (10)° with that of the methoxyphenolate ring. In the crystal, molecules of the PdIIcomplex are arranged into sheets parallel to theacplane, and the chloroform solvent molecules are located in the interstitial areas between the complex molecules. Weak intermolecular C—H...O and C—H...π interactions stabilize the packing.

In the cation, the average Sb—N distance is 2.066 (2) Å, while the Sb—Cl distances are 2.3410 (11) and 2.3639 (12) Å. The central unit of the cation, SbN4C20, is far from being planar, with deviations of atoms from the least-squares plane ranging from −0.110 (4) to 0.124 (4) Å. The Sb—Cl distances in the anion, which is located about an inversion center, lie in the wide range 2.3715 (13)–2.7489 (13) Å, the longest distances being between the Sb and bridging Cl atoms. The crystal structure is stabilized by intermolecular C—H...Cl interactions involving the cations, the anions and the solvent molecules. The solvent molecule is disordered over two orientations in a 0.901 (13):0.099 (13) ratio.
