## Abstract Partially unsaturated 14β and 28βmembered thiacrown ethers, **3** and **4**, which possess alternating Zβcarbonββcarbon double bonds and propylene chains, were synthesized by stepwise reactions. The crystal structure of larger cyclic compound **4** was determined by Xβray crystallograph
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.
