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.
