Synthesis and Characterisation of a Novel Copper(II) Azamacrocycle-Phosphonate 3D Polymeric Network

A new azamacrocycle phosphonate in its hydrocloride form (1) has been synthesized and characterised by multinuclear NMR spectroscopy and by a single X-ray analysis. The reaction of 1 with CuII ions gives a polymeric compound (2), which exhibits an unprecedented three-dimensional network containing two-dimensional channels filled with guest molecules. The solid-state structure of 2 and its properties have been characterised by means of various analytical methods which include single-crystal X-ray structure analysis, X-ray powder diffraction, thermogravimetric studies as well as magnetic susceptibility and EPR measurements.
