A 1D Schiff base zinc polymer as a versatile metallo-ligand for the synthesis of polynuclear zinc cages

Abstract

The 1D polymeric Schiff base zinc complex, [LZn2Et2]n, where LH2 = (NN′-ethylene-bis(4-iminopentan-2-one)) has been demonstrated as a useful synthetic metallo building block for the synthesis of homo and heteronuclear zinc cages. The reaction of [LZn2Et2]n with CdI2 afforded the hetero-nuclear cage, 1, [L2Zn4(Et)2CdI4], while reaction with HgI2 afforded a hexanuclear zinc cage, [L2Zn6(Et)44O)(μ3OEt)I], 2. The versatility of [LZn2Et2]n as a metallo building block is demonstrated through the reaction with ferrocenyl carboxylic acid, affording the ferrocenyl supported zinc cage, [L2Zn8(FcCO2)4(Et)2(OEt)24O)2], 3, while the reaction with Er(III) acetate afforded the decanuclear zinc cage, [L3Zn104O)4(Et)6], 4.
