Construction of a highly symmetric nanosphere via a one-pot reaction of a tristerpyridine ligand with Ru(II).

A three-dimensional, highly symmetric, terpyridine-based, spherical complex was synthesized via the coordination of four novel, trisdentate ligands and six Ru2+ ions, and it exhibits excellent stability over a wide range of pH values (1–14). Structural confirmation was obtained by NMR and ESI-TWIM-MS.
