A Self-Assembled Dinuclear Double-Stranded Helicate Based on a Square-Planar Coordination Geometry

Abstract

The nickel(II) complex of a new bis-N,O-bidentate Schiff base, in which two salicylaldiminate units are connected by an α,α′-dioxo-ortho-xylidene spacer via the 3-position of salicyl moieties, was structurally characterised in the solid state and in solution as a dinuclear double helicate based on a square-planar coordination geometry.
