Abstract
The title compound, formed by reaction of 4-mercapto-4-methylpentan-2-one with
bis(ethane-1,2-diamine)nickel(II) perchlorate, has a centrosymmetrical
dinuclear cation. Each singlet ground-state nickel(II) ion is in tetrahedrally
twisted square-planar coordination by the primary amine and imine nitrogen
atoms and the thiolato sulfur atom of one molecule of
7-amino-2,4-dimethyl-5-azahept-4-ene-2-thiolate (adet¯), and the sulfur
atom of another molecule, with the sulfur atoms of two ligands forming a
planar Ni2S2 bridging group
