| Abstract: | A novel approach to heteroleptic heteronuclear rare earth metal(III) trisphthalocyaninates was proposed with the complexes (15C5)4Pc]M*(15C5)4Pc]M(Pc) as examples (15C5 is 15-crown-5, Pc2? is the phthalocyaninate dianion, and M* ?? M = Yb and Y). Unsubstituted lanthanum bisphthalocyaninate, La(Pc)2, was used for the first time as a Pc2? donor in the synthesis of such complexes. This substantially increased the yields of the target heteronuclear complexes over the previous literature data. |
