A novel class of dimeric nickel(II) compounds with quadridentate nitrogen ligands: the crystal structure of [Ni2(C16H16N6)2]
Abstract
The dianionic tricyclic quadridentate Schiff base ligands derived from 2-pyridylhydrazine and 1,2-diones form dimeric nickel(II) and palladium(II) species of a novel type, which apparently have a significant metal–metal bonding interaction, and which may be readily oxidised.
