Five transition metal complexes based on the ligand 9,10-anthraquinone-1,3-dicarboxylate acid (1,3-H2AQDC) have been synthesized and characterized by physico-chemical and spectroscopic methods. Single-crystal analyses show that the complexes {Mn(1,3-AQDC)(H2O)4·(H2O)}n, {Zn(1,3-AQDC)(H2O)4·(H2O)}n, {Ni(1,3-AQDC)(4,4′-bpy)(H2O)2(CH3OH)}n and {Co(1,3-AQDC)(4,4′-bpy)(H2O)2(CH3OH)}n (4,4′-bpy = 4,4′-bipyridine) comprise one-dimensional (1D) chains in their crystal structures, while [Ni(1,3-AQDC)(H2O)4·(H2O)3]2 bears dimeric units, and these secondary building units are further linked by hydrogen bonding to form three-dimensional structures. These compounds proved to be able to catalyze visible-light-driven air-oxidation reactions of diarylethyne into diketones under mild conditions.

基于 9,10-蒽醌-1,3-二羧酸盐的过渡金属配合物的合成、晶体结构和光催化性能

已经合成了五种基于配体 9,10-蒽醌-1,3-二羧酸 (1,3-H2AQDC) 的过渡金属配合物，并通过物理化学和光谱方法对其进行了表征。单晶分析表明配合物{Mn(1,3-AQDC)(H2O)4·(H2O)}n, {Zn(1,3-AQDC)(H2O)4·(H2O)}n, {Ni (1,3-AQDC)(4,4'-bpy)(H2O)2(CH3OH)}n 和 {Co(1,3-AQDC)(4,4'-bpy)(H2O)2(CH3OH)} n (4,4'-bpy = 4,4'-联吡啶) 在其晶体结构中包含一维 (1D) 链，而 [Ni(1,3-AQDC)(H2O)4·(H2O)3]2带有二聚单元，这些二级结构单元通过氢键进一步连接形成三维结构。事实证明，这些化合物能够在温和条件下催化可见光驱动的二芳基乙炔空气氧化反应生成二酮。
