✦ Synopsis

The bis-monodentate ligands 1 and 2 based on the interconnection of two pyrazolyl units by CH 2 (CH 2 OCH 2 ) n CH 2 (n=3 or 4) spacers, respectively, lead to the formation of either mono nuclear silver metallamacrocycle 10 in the case of 1 or binuclear silver metallamacrocycle 11 in the case of 2. Both complexes have been characterised in the solid state by X-ray diffraction on single crystals.
