Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>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‐<italic>tert</italic>‐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.</p> </abstract>
