4,4′-(Triaz-1-ene-1,3-diyl)dipyridine (L) and the first transition metal complex with it are synthesized. It is found that the solid phase of isolated solvate [Cu(hfac)2L]·0.5MePh, where hfac is hexafluoroacetylacetonate, consists of polymer chains inside which L acts as a bridge, linking together Cu(hfac)2 moieties by N atoms of pyridine rings. The chains, in turn, are arranged into layers by H bonds. The result shows that L can be a bridging ligand in the synthesis of new coordination polymers.

1,3-二(4-吡啶基)三氮烯：一种用于合成配位聚合物的新配体

合成了 4,4'-(Triaz-1-ene-1,3-diyl)dipyridine (L) 及其第一个过渡金属配合物。发现分离的溶剂化物 [Cu(hfac)2L]·0.5MePh 的固相，其中 hfac 是六氟乙酰丙酮化物，由聚合物链组成，其中 L 作为桥，通过 N 原子将 Cu(hfac)2 部分连接在一起吡啶环。反过来，这些链通过 H 键排列成层。结果表明L可以作为新配位聚合物合成中的桥连配体。
