Bioinspired model complexes for vanadium haloperoxidases
Synthesis and structural characterization of monooxo-and cis -dioxovanadium(v) complexes based on tridentate N-salicylidene carbonic acid hydrazide ligands are reported. By functionalization of the aliphatic side-chain of the chelate system, vanadium(v) compounds were obtained, which structurally mi...
