Bimetallic complexes with porphyrins containing a cyclometalated phenylpyridine group

Abstract

Treatment of Ni(HP 1) (H 3P 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 2CNEt 2 to give Pd(S 2CNEt 2)[Ni(P 1)]. Reaction of Ni(HP 1) with [Ir(H) 2(PPh 3) 2(Me 2CO) 2][BF 4] afforded Ir(H)Cl(PPh 3) 2[Ni(P 1)]. The crystal structures of Pd(S 2CNEt 2)[Ni(P 1)] and Ir(H)(Cl)(PPh 3) 2[Ni(P 1)] have been determined.
