The reaction of a diphenylpyridine with one equivalent of potassium tetrachloroplatinate in ethanoic acid yields a cyclometallated species which can be induced to undergo a second cyclometallation to give a C∧N∧C tridentate species. Carbonyl derivatives of two such compounds have been structurally characterised. The X-ray structure of the complex [2,6-(4′ -C6H13OC6H3)2C 5H3NPt(CO)], (1), obtained using 2,6-bis(4′ -hexyloxyphenyl)pyridine, has no unusual features. In contrast, the structure of the complex [2,6-(C6H4)2-4-(4′ -C8H17OC6H5)C5H 2NPt(CO)], (2), which results when using 4-(4′ -octyloxy-phenyl)-2,6-diphenylpyridine, has close intermolecular contacts, with a Pt-Pt bond of 3.243(1) A holding the molecules together as dimers. Compound 2 also exists in another form in the solid state, a form that does not appear to contain Pt-Pt bonds.

Metalation of 2,6-diphenylpyridine (1) by potassium tetrachloroplatinate in acetic acid gives a monocyclometalated chloride-bridged dimer 4. This dimer is split with CO to give a kinetic product 9t with the incoming CO trans to the orthometalated carbon.
