Cobalt(III)-py(2)en systems as potential carriers of beta-ketoester-based ligands

Two cobalt(III) complexes containing different β-ketoesters, namely [CoIII(L1)(py2en)](ClO4)2·H2O (1) and [CoIII(L2)(py2en)](ClO4)2 (2) (py2en = N,N′-bis(pyridin-2-ylmethyl)ethylenediamine; L1− = methylacetoacetate; L2− = ethyl 4-chloroacetoacetate) have been prepared and investigated as prototypes...
