A synthetic route leading to bis‐heteroleptic cyclometalated complexesis described. The complexes [2‐(2′‐thienyl)pyridinato‐ N , C ‐ 3′ ]{2‐[3′‐(trimethylsilyl)2′‐thienyl]pyridinato‐ N, C 3′ }platinum(II) ([Pt(thpy) (TMS‐thpy)]; I ) and (l‐phenylpyrazolato‐ N 2 , C 2′ )[2‐(2′‐thienyl)pyridinato‐ N , C 3′ ]platinum ([Pt(Phpz)(thpy)]; II ) are characterized by UV/VIS, NMR, and mass spectroscopy. Thermal and photochemical oxidative addition reactions yield two out of the 10 possible pairs of enantiomers of octahedral Pt(IV) compounds.
