    • We are well aware that in addition to these two examples there are many other cases of structurally characterized cis -(R)(olefin) complexes especially with Pt and nitrogen chelate ligands. A CSD search (June 16, 2010) resulted in over 70 hits. Platinum systems, however, neither are active polymerization catalysts (they may dimerize olefins) nor do they show structures analogous to the ones reported here
