Synthesis of binuclear ligands possessing two discrete multidentate N-heterocyclic podand coordination sites and their bimetallic nickel(II) complexes
Binuclear ligands possessing two discrete multidentate N-heterocyclic podand coordination sites connected by a flexible propylene spacer and a rigid m-xylene spacer were synthesized. Treatment of the binuclear ligands with Ni(OAC)(2) afforded the bimetallic nickel(II) complexes with two discrete nickel centers. The single-crystal X-ray structure determination of the bimetallic nickel(II) complex with a propylene spacer revealed a little distorted square planar geometry at each nickel center.
