Abstract
A half-sandwich coordination complex, useful for the synthesis of triple-decker sandwich coordination compounds, is produced by reacting a precursor complex of the formula XM(R1)2 wherein X is a halogen, M is a metal, and R1 is an amide, with a free base porphyrinic macrocycle to produce said half-sandwich complex. The half-sandwich coordination complex can be used to make a triple-decker sandwich coordination compound by reacting a half-sandwich coordination complex as described above with a double-decker sandwich coordination compound.
