      Abstract: m-Terphenyls are mols. with a central   Ph ring possessing at least two meta aryl substituents that twist   out of the plane of the central Ph ring to form a bowl-shaped   pocket. These bulky ligands are known to reliably enforce low   coordination nos. around metals bound within the pocket. Our   interest in unusual bonding modes for main group elements has led   us to combine the unusual steric protection of m-terphenyls with   the flexible bonding modes of carboxylates (monodentate, chelate,   bridging, etc.). We have developed a series of low coordinate   main group complexes based primarily upon tin (II). The   carboxylate complexes typically form bridging dimers with a   Sn2O4C2 core. The synthesis and reactivity of these and other   complexes will be presented, including the oxidn. to Sn(III)   which results in rearrangement to a Sn2N2 dimer with   extra-annular monodentate carboxylate coordination.
