The facile synthesis of anionic bipyridyl ligands with dinuclear clathrochelate cores is described. These metalloligands can be obtained in high yields by the reactions of M(ClO4)2(H2O) 6 (M: Zn, Mn, or Co) with 4-pyridylboronic acid and 2,6-diformyl-4-methylphenol oxime or 2,6-diformyl-4-tert-butylphenol oxime, followed by deprotonation. The ligands are interesting building blocks for metallasupramolecular chemistry, as evidenced by the formation of a Pt-based molecular square and four coordination polymers with 2D or 3D network structures. Competition experiments reveal that the utilization of anionic bipyridyl ligands can result in significantly more stable assemblies. Its good to be negative: Anionic bipyridyl ligands with dinuclear clathrochelate cores (see scheme) are easily obtained from simple starting materials. These ligands are interesting building blocks for metallasupramolecular chemistry. The utilization of anionic bipyridyl ligands can result in significantly more stable assemblies.
