Chloro-bridged Cu(II) pairs linked into a 1D coordination polymer through a dinucleating imidazole-based ligand: 3D structure and magnetism

An interesting 1D polynuclear copper(II) complex built from tetranuclear units is reported with the ligand 1,1,7,7-tetrakis(imidazol-2-yl)-2,6-diazaheptane. The tetranuclear building blocks contain both neutral and anionic monodentate imidazole groups. The dehydronated imidazole is strongly hydrogen bonded to a lattice water molecule.
