Organometallic Ruthenium half-sandwich complexes and 5?(2-hydroxyphenyl)?1H?tetrazole(LH2) have been used in the construction of supramolecular cages. The reaction of dimeric (p-cymene)RuCl2 and LH2 in a ratio of 2:1 and 1:1 produced bridged Ru complexes by LH and Cl and two LH and methoxide respectively. Also, by controlling the reaction ratios, two types of rectangular supramolecules were formed in a ratio of 4:4 and 6:4 (Ru:L). The latter contained two ruthenocene units which have η6 binding mode with half of L ligand. More interesting results were achieved when additional AgOTf was used. The reaction of (p-cymene)RuCl2 : LH2 : additional AgOTf in the ration of 6 : 6 : 18 and 6 : 6 : 20 resulted in the formation of unique two supramolecules having molecular ratio of 6 : 6 : 6 or 6 : 6 : 8 for Ru : L : Ag, which show cylindrical and double-cone shaped structures, respectively. They were characterized by 1H-NMR, IR, ESI-MASS and their solid state structures were confirmed by X-ray crystallography.
