Piano‐stool‐shaped platinum group metal compounds, stable in the solid state and in solution, which are based on 2‐(5‐phenyl‐1H‐pyrazol‐3‐yl)pyridine ( L ) with the formulas [(η 6 ‐arene)Ru( L )Cl]PF 6 {arene = C 6 H 6 ( 1 ), p ‐cymene ( 2 ), and C 6 Me 6 , ( 3 )}, [(η 6 ‐C 5 Me 5 ) M ( L )Cl]PF 6 { M = Rh ( 4 ), Ir ( 5 )}, and [(η 5 ‐C 5 H 5 )Ru(PPh 3 )( L )]PF 6 ( 6 ), [(η 5 ‐C 5 H 5 )Os(PPh 3 )( L )]PF 6 ( 7 ), [(η 5 ‐C 5 Me 5 )Ru(PPh 3 )( L )]PF 6 ( 8 ), and [(η 5 ‐C 9 H 7 )Ru(PPh 3 )( L )]PF 6 ( 9 ) were prepared by a general method and characterized by NMR and IR spectroscopy and mass spectrometry. The molecular structures of compounds 4 and 5 were established by single‐crystal X‐ray diffraction. In each compound the metal is connected to N1 and N11 in a k 2 manner.
