  The X-ray crystal structure of the N2 isomers of the Ru(bipy)2 complexes of Hphpztr (1) and Hpztr (2), (bipy = 2,2′-bipyridine, Hphpztr = 2-(5′-phenyl-4′H-[1,2,4]triazol-3′-yl)pyrazine and Hpztr = 2-(4′H-[1,2,4]triazol-3′-yl)pyrazine) are reported. The molecular structure obtained for 2 demonstrates an interesting structural aspect in the sharing of a single proton between two molecular units. The isolation of the Δ and Λ stereoisomers of 1 and [Ru(phen)2(pztr)]+ (phen = 1,10-phenanthroline) (3) by semipreparative HPLC is also reported. The compounds obtained are characterised by electronic spectroscopy and particular attention is paid to the photophysical properties of Δ and Λ isomers of 1 and 3, in chiral enantiopure and racemic solvents.

  报告了Hphpztr（1）和Hpztr（2）的Ru（bipy）2复合物N2异构体的X射线晶体结构（bipy = 2,2′-联吡啶，Hphpztr = 2-(5′-苯基-4′H-[1,2,4]三唑-3′-基)吡嗪，Hpztr = 2-(4′H-[1,2,4]三唑-3′-基)吡嗪）。2的分子结构表明，两个分子单元之间共享一个质子，这是一个有趣的结构方面。还报告了通过半制备HPLC分离1和[Ru（phen）2（pztr）]+的Δ和Λ立体异构体（phen = 1,10-菲咯啉）的分离（3）。所获得的化合物的特征在于电子光谱，并特别关注1和3的Δ和Λ异构体在手性对映纯溶剂和消旋溶剂中的光物理性质。
