Hydrogenated Schiff base ligands: Towards the controlled organisation of open metal frameworks

Abstract

The synthesis and structures of bis-((μ²-acetato-O,O)-μ-(N,N'-bis-(o-hydroxybenzyl)-1,3-diaminopropane)-(aquo)nickel)nickel, bis-((μ²-acetato-O,O')-μ-(N,N'-bis-(o-hydroxybenzyl)-1,4-diaminobutane nickel)nickel acetate) and bis-((μ²-acetato-O,O')-μ-(N,N'-bis(o-hydroxybenzyl)-1,4-diaminobutane)-(dimethylformamido)nickel)nickel are reported. These compounds are designed to draw attention to the wider structural catalogue available to symmetrical hydrogenated Schiff base complexes which contain a tetramethylene backbone.
