摘要：

The tricyclic bisamidines L1 and L2 are designed to be preconstrained so as to present synperiplanar donor sites for metal coordination. Their very different bite angles of 35 degrees and 70 degrees result from the incorporation of two five-membered instead of six-membered rings in their respective backbones. Distinct coordination preferences in a variety of metal complexes have now been confirmed by X-ray structural studies. While L1 afforded monodentate, symmetrical and unsymmetrical chelating as well as bimetallic bridging modes in its complexes, L2 has been found exclusively in a bidentate chelating mode.
