A series of five new syn-bidentate ligands 14−18 based on the [1.1.1.1]metacyclophane backbone blocked in a 1,3-alternate conformation was achieved. The common building block for the preparation of ligands bearing two interaction sites located in a syn fashion (CN, SMe, p-pyridyl, p-methoxyphenyl and p-methylthiophenyl) is the dibromo derivative 12. All reported ligands were fully characterised by
