An additional goal was the identification of new synthetic pathways affording hybrids based on the diruthenium unit. The proposed strategy challenged the use of CuAAC reactions with the formation of triazole connectors. Azide-alkyne click reactions proved as a valuable way for the postfunctionalization of metal complexes , whereas the triazole linkers exhibit favorable properties, including a moderate dipole character, hydrogen-bonding capability, rigidity, and stability 113 .
