“…The V1 ion lies 0.3485 (17) Å above the equatorial plane towards O4. The V1-N3 bond is significantly longer [2.340 (3) Å] (Table 1), similar to the reported vanadium(V) complex (Bian et al, 2011;Cao et al, 2011;Xu et al, 2005;Li et al, 2010;Li et al, 2006;).…”

“…The V2 atom deviates 0.297 (3) Å from the equatorial plane, formed by O7, N2, O9 and O12, towards O10. The axial O6 and O11 atoms are involved in long V-O distances [V1-O6 and V2-O11 = 2.345 (6) and 2.330 (6) Å], which is similar to the reported vanadium(V) complexes (Bian & Li, 2011;Cao et al, 2011;Chen et al, 2004)…”

In the title complex, [V(C13H15NO3)O(CH3O)(CH3OH)], the VV atom is six-coordinated by a tridentate O,N,O′-donor ligand, derived from the condensation of salicylaldehyde and l-isoleucine, a vanadyl O atom, a methanolate O atom and a methanol O atom in a distorted octahedral geometry. The asymmetric unit contains two complex molecules. In the crystal, intermolecular O—H⋯O and C—H⋯O hydrogen bonds connect the molecules into a one-dimensional chain along [100].

“…Examples are halogenation, decarbonylative halogenation, (enantioselective) sulfoxidation in the absence of halides, epoxidation, hydroxylation of alkenes, and oxidation of primary and secondary alcohols analogous to the native enzyme . Homogenous complexes with established kinetics are Schiff‐base complexes of vanadium, N ‐heterocycle‐vanadium pincer compounds, as well as imidazole, scorpionate and amino acid complexes . Vanadium acetylacetonate and ammonium metavanadate have found applications as “green” catalysts .…”

Transition-metal oxide nanoparticles and molecular coordination compounds are highlighted as functional mimics of halogenating enzymes. These enzymes are involved in halometabolite biosynthesis. Their activity is based upon the formation of hypohalous acids from halides and hydrogen peroxide or oxygen, which form bioactive secondary metabolites of microbial origin with strong antibacterial and antifungal activities in follow-up reactions. Therefore, enzyme mimics and halogenating enzymes may be valuable tools to combat biofilm formation. Here, halogenating enzyme models are briefly described, enzyme mimics are classified according to their catalytic functions, and current knowledge about the settlement chemistry and adhesion of fouling organisms is summarized. Enzyme mimics with the highest potential are showcased. They may find application in antifouling coatings, indoor and outdoor paints, polymer membranes for water desalination, or in aquacultures, but also on surfaces for food packaging, door handles, hand rails, push buttons, keyboards, and other elements made of plastic where biofilms are present. The use of natural compounds, formed in situ with nontoxic and abundant metal oxide enzyme mimics, represents a novel and efficient "green" strategy to emulate and utilize a natural defense system for preventing bacterial colonization and biofilm growth.
