Bis(benzimidazolyl)amine copper complexes with a synthetic 'histidine brace' structural motif relevant to polysaccharide monooxygenases

Bis(benzimidazole)amine-copper complexes with a N3 donor set adopt trigonal bipyramidal geometries, with a T-shape ligand disposition similar to the 'histidine brace' structural motif in the active site of polysaccharide monooxygenases.139
