Bis(benzimidazolyl)amine copper complexes with a synthetic 'histidine brace' structural motif relevant to polysaccharide monooxygenases
(2014) In Inorganica Chimica Acta 422. p.152-157- Abstract
- Reaction of Cu2+ salts with the benzimidazole-N-methylated bis[(1-methyl-2-benzimidazolyl)ethyl]amine ligand 2BB results in either bi- or monometallic complexes. Spectroscopic and solid state characterization reveals either square pyramidal or trigonal bipyramidal coordination geometries around the cupric ions. In [{2BBCu(mu-F)}(2)](BF4)(2), the dicopper structure is determined by the bridging nature of the fluoro ligands, which complement the T-shape arrangement of N-3 donors provided by 2BB to define a square pyramidal (or capped distorted tetrahedral) coordination geometry. The monocopper complexes 2BBCuCl(2) and [2BBCu(H2O)(2)](OTf)(2) are characterized by a trigonal bipyramidal geometry both in solution and in the solid state. In all... (More)

In all complexes, the T-shape N-3 donor set of 2BB is analogous to the coordination environment of the copper ions provided by a 'histidine brace' and an additional histidine imidazole in the active site of polysaccharide monooxygenases.
