Hexanuclear [Ni6L12] metallacrown framework consisting of NiS4 square-planar and NiS5 square-pyramidal building blocks†‡
Abstract
The hexanuclear [Ni6L12] (2) wheel-type cluster adopts an unusual structural motif whereby four NiS4 square-planar and two NiS5 square-pyramidal units are conjoined by edge sharing; the NiS5 units resemble the Ni centre of the inactive state in the [NiFe] hydrogenase.
