A bridging coordination mode of urea and carbamate at a dinuclear nickel(II) centre
Abstract
Starting from an active O2H3-bridged bimetallic complex, a bridging coordination mode of both urea and carbamate—the substrate and its first hydrolytic product in urease activity—at a dinickel(II) centre relevant to the active site of the metalloenzyme has been characterised structurally.
