2,2′:6′,2″-Terpyridine (terpy) ligands and their iron(II) and cobalt(II) complexes bearing first and second generation Fréchet-type dendritic wedges have been prepared and structurally characterised. The rotational freedom within the dendritic wedge results in a great diversity in conformational space. Structural studies are reported on first generation species and their metal complexes, and the variety of inter- and intramolecular interactions which dominate the conformation of the dendrimer and the packing of the molecules (ions) in the lattice are discussed.
2,2′:6′,2″-三联吡啶(terpy)配体及其铁(II)和钴(II)配合物,携带第一代和第二代Fréchet型树枝状楔,已被制备并结构表征。树枝状楔内的旋转自由度导致了构象空间的极大多样性。本文报道了第一代物种及其金属配合物的结构研究,并讨论了主导树枝状结构构象和分子(离子)在晶格中堆积的各种分子间和分子内相互作用。
