Neutral metallomacrocycles with four or ten (PEt3)Pd(II) centers.
The reaction of [(Et(3)P)PdCl(2)](2) with 2,3-dihydroxypyridine, 5-chloro-2,3,-dihydroxypyridine, or 2-hydroxynicotinic acid in the presence of base gives neutral, metallomacrocyclic compounds in which the heterocycles act as dianionic, bridging ligands. The macrocycles contain four or ten palladium atoms as evidenced by single crystal X-ray analyses.
