Abstract
Stoichiometric
control of Ru, Ag, and tetrazolyl ligands resulted
in the formation of different heterometallic Ru–Ag supramolecular
architectures. Although the reaction of Ru and 5-(2-hydroxyphenyl)-1<i>H</i>-tetrazolyl (<i><b>L</b></i>H<sub>2</sub>) in a molar ratio of 2:1 or 6:4 resulted in the formation of dimeric
or hexameric Ru complexes, Ag metal ions caused the Ru complexes to
form three-dimensional cylindrical Ru<sub>6</sub>Ag<sub>6</sub><i><b>L</b></i><sub>6</sub> and double-cone-shaped Ru<sub>6</sub>Ag<sub>8</sub><i><b>L</b></i><sub>6</sub> complexes
by occupying vacant coordination sites
