We report the synthesis and characterization of some dinuclear organoplatin
um(II) species where 2,2':6',2''-terpyridine (terpy) behaves as a 2-fold-de
protonated N,C<^>C,N ligand bridging two [Pt(CH3)(L)] units (L = neutral li
gand). Each platinum atom is further bonded to a nitrogen of a terminal pyr
idine and to a 3' or 5' carbon atom of the inner pyridine ring. As far as w
e know, these are the first examples of cyclometalated terpy as well as of
a 3,5-dimetalated pyridine ring. The X-ray structure of one of these specie
s (L = CO) shows it to be an organoplatinum polymer.
