一种由不寻常的羟基羧酸盐配体形成的铜配合物：[Cu(bpy)(CHO)] 。 （注：原文中“hy-droxy-carboxyl-ate”表述有误，推测正确应为“hydroxy-carboxylate” ；“CHO”指代不明，这里按原文翻译）
A copper complex of an unusual hy-droxy-carboxyl-ate ligand: [Cu(bpy)(CHO)].

A copper(II) complex, (2,2'-bi-pyridine-κ ,')[2-hy-droxy-2-(hy-droxy-methyl-κ)propane-dioato-κ , ]copper(II), [Cu(CHO)(CHN)], containing the unusual anionic chelating ligand 2-(hy-droxy-meth-yl)tartronate, has been synthesized. Cu(bpy)(NO) was mixed with ascorbic acid and Dabco (1,4-di-aza-bicyclo-[2.2.2]octa-ne) in DMF (dimethylformamide) solution in the presence of air to produce the title compound. The structure consists of square-pyramidal complexes that are joined by Cu⋯O contacts [2.703 (2) Å] into centrosymmetric dimers. The CHO ligand, which occupies three coordination sites at Cu, has previously been identified as an oxidation product of ascorbate ion.
一种铜（II）配合物，（2,2'-联吡啶-κ²，')[2-羟基-2-(羟甲基-κ)丙二酸根-κ²，κ³]铜（II），[Cu(CHO)(CHN)]，含有不寻常的阴离子螯合配体2-(羟甲基)酒石酸根，已被合成。Cu(bpy)(NO)在空气中与抗坏血酸和达布科（1,4-二氮杂双环-[2.2.2]辛烷）在DMF（二甲基甲酰胺）溶液中混合以制备标题化合物。该结构由通过Cu⋯O接触[2.703 (2) Å]连接成中心对称二聚体的四方锥配合物组成。在铜上占据三个配位点的CHO配体先前已被鉴定为抗坏血酸离子的氧化产物。
