title: 1,3-Bis(thiophosphinoyl)indene: a unique and versatile scaffold for original polymetallic complexes.
abstract: 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(Ph(2)P═S)(2)}PdCl](-) was found to behave as a κ(2)-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 d(8)···d(8) interactions with a quasi-perpendicular arrangement of their coordination planes.
