چکیده
The hexanuclear [Ni(6)L(12)] (2) wheel-type cluster adopts an unusual structural motif whereby four NiS(4) square-planar and two NiS(5) square-pyramidal units are conjoined by edge sharing; the NiS(5) units resemble the Ni centre of the inactive state in the [NiFe] hydrogenase.

Reduction of protons assisted by a hexanuclear nickel thiolate metallacrown: protonation and electrocatalytic dihydrogen evolution.
The hexanuclear metallacrown [Ni6L12] (L is mu-S-CH2-CH2-S-C6H4-Cl) has been demonstrated to functionally resemble the [NiFe] hydrogenases. Protonation of the [Ni6L12] cluster was studied employing 1H NMR spectroscopy by the sequential additions of dichloroacetic acid or p-toluenesulfonic acid monohydrate into solutions of [Ni6L12] in CD2Cl2 and DMF-d7, respectively; protonation takes place on ...
