Porphyrin and Phthalocyanine Chemistry

A general synthetic strategy for making, and structures and some properties of, several new polynuclear nickel complexes of pyridonate ligands are reported: these complexes include a linear trinuclear complex [Ni3(ChP)4(O2CMe)2(MeOH)6], a tetranuclear cubane [Ni4(OMe)4(η-ChP)(ChP)3(MeOH)7] and two undecanuclear complexes [Ni11(µ-OH)6(O2CMe)6(mhp)9(H2O)3]2[CO3] and [Ni11(µ3-OH)6(O2CMe)7(mhp)9(Hmhp)2](Hchp and Hmhp = 6-chloro- and 6-methyl-2-pyridone respectively).
