Bimetallic complexes with porphyrins containing a cyclometalated phenylpyridine group

Treatment of Ni(HP1) (H3P1 = meso-5-[4'-(2''-pyridyl)phenyl]-10,15,20-triphenyporphyrin) with K-2[PdCl4] in EtOH afforded [Pd{Ni(P-1)}](2)(mu-Cl)(2) that reacted with NaS2CNEt2 to give Pd(S2CNEt2)[Ni(P-1)]. Reaction of Ni(HP1) with [Ir(H)(2)(PPh3)(2)(Me-2-CO)(2)][BF4] afforded Ir(H)Cl(PPh3)(2)[Ni(P-1)]. The crystal structures of Pd(S2CNEt2)[Ni(P-1)] and Ir(H)(Cl)(PPh3)(2)[Ni(P-1)] have been determined.
