Coordination diversity of copper(II) phosphoryl-functionalized salicylaldiminates: Effect of the length of the pendant phosphoryl arm

Complexation of phosphorylated salicylaldimines with Cu(II) ions selectively provides four-, five-, and six-coordinate copper(II) complexes, including an unusual mixed iminate-aldehydate derivative used as a precursor for unsymmetrical Schiff base complexes.
