“…[13] Wu et al reported on a discrete heptanuclear [Cu 7 (N 3 ) 16 ] 2À azidocuprate anion stabilised by a bulky cation, which was in situ generated by condensation of pyridine-2-carbaldehyde and 2-[(pyridin-2-ylmethylene)amino]ethanol. [14] A recent publication reports about tri-and tetranuclear copper(II) azido complexes. [15] Non-covalent interactions of [Cu(N 3 ) 4 ] 2ions are studied in ref.…”

In chemical reactions of copper(II) acetate dihydrate with imidazolium azide salts in ethanol solution several new homoleptic azidocuprates(II) were obtained. In dependency of the used counter cation various different azidocuprate moieties were crystalized. The doubly charged DMMDIm2+ cation facilitates the formation of mononuclear [Cu(N3)4]2– complex anions, while the utilisation of the (PeMIm)+ ion enables the isolation of a di‐nuclear [Cu2(N3)6]2– salt. By using the unsymmetrical imidazolium ions (BMIm)+ or (EMIm)+ salts with the tri‐nuclear [Cu3(N3)8]2– complex anion are obtained. With the (DML)+ cation an azidocuprate(II) crystallizes , which contains both [Cu(N3)4]2– and the [Cu2(N3)6]2– anion. The anions in the salt with the (PeMIm)+ cation are interconnected through further Cu−N bonds and form layers with a 2D‐honecomb structure. The tri‐nuclear units in the (BMIm)+ and the (EMIm)+salts form coordination strands of different structures.

The reaction of the low melting solid PPN(N3) with copper(II) acetate in ethanol yields (PPN)2[Cu11(N3)24(C2H5OH)2]. The undecanuclear azidocuprate dianon is unprecedented and represents the largest example for a discrete azidocuprate(II) anion to date. This structurally more‐or‐less flat anion contains features of Cu(N3)2, i. e. can be considered the largest so far known building block of this solid.
