The coordination of tridentate ligands featuring lateral coordination sites prone to acting as bridging ligands was explored with the aim of obtaining original polymetallic species in a straightforward and controlled manner. Accordingly, the 2-indenylidene chloropalladate [{Ind(Ph2PS)2}PdCl]− was found to behave as a κ2-C,S bidentate ligand toward metal fragments, giving access to homo- and heteropolymetallic complexes. X-ray diffraction analyses reveal the presence of short metal–metal contacts in all of these complexes. Density functional theory calculations unambiguously substantiate that the metals engage in unusual d8···d8 interactions with a quasi-perpendicular arrangement of their coordination planes.
