Synthesis, crystal structure and magnetic properties of poly[[diaqua{μ6-2-[bis(carboxylatomethyl)amino]terephthalato}dicobalt(II)] 1.6-hydrate]

Abstract

The title compound, {[Co2(C12H7NO8)(H2O)2]·1.6H2O}n, features tetranuclear CoII units bridged by κ 3 O:O:O′- and κ 3 O:O,O′-carboxylate groups from deprotonated 2-aminodiacetic terephthalic acid, which are joined into CoII ribbons via syn–anti carboxylate bridges. The parallel-aligned adtp4− ligands with an alternately reversed arrangement further link adjacent CoII ribbons into (010) layers, which are assembled into a three-dimensional supramolecular architecture via intermolecular hydrogen bonds.
