of one or two 2,2′‐bipyridine units at the upper rim of the calix[4]arene platform was performed by means of the Wittig reaction. The resulting alkenes were hydrogenated to give two new bipyridyl‐based calixarene podands, which were studied as ligands for Co II cation. The mono‐bipyridyldichlorocobalt complex was notably fully characterised by 1 H‐NMR and X‐ray crystal structure analyses, which confirmed the tetrahedral coordination mode involving the bipyridyl subunit and the two chlorine atoms around the cobalt centre.
