Bimetallic complexes with porphyrins containing a cyclometalated phenylpyridine group

Abstract Treatment of Ni(HP 1 ) (H 3 P 1  =  meso -5-[4′-(2″-pyridyl)phenyl]-10,15,20-triphenyporphyrin) with K 2 [PdCl 4 ] in EtOH afforded [Pd{Ni(P 1 )}] 2 (μ-Cl) 2 that reacted with NaS 2 CNEt 2 to give Pd(S 2 CNEt 2 )[Ni(P 1 )]. Reaction of Ni(HP 1 ) with [Ir(H) 2 (PPh 3 ) 2 (Me 2 CO) 2 ][BF 4 ] afforded Ir(H)Cl(PPh 3 ) 2 [Ni(P 1 )]. The crystal structures of Pd(S 2 CNEt 2 )[Ni(P 1 )] and Ir(H)(Cl)(PPh 3 ) 2 [Ni(P 1 )] have been determined.
