Starting from diethyl 5-(methylethyl)pyridine-2,3-dicarboxylate the cr
ystalline and highly soluble complex -methylethyl)-[29H,31H-tetrapyrid
o[2,3-b:2',3'-g:2 ''-3 ''-3 azinato(2-)N29,N30,N31,N32]-nickel-[Eu(fod
)(3)](4) was prepared. In this compound each europium ligand is coordi
nated to a pyridine N-atom and neighboured N-atom of the porphyrazine
ring.
