Two Cu(II)-malonate complexes with 2-amino-4-methylpyridine (complex 1) and 2-aminopyrimidine (complex 2) auxiliary ligands were synthesized, and their single-crystal X-ray diffraction structures were established. Change in the auxiliary ligand exhibits substantial structural variation in the present complexes. Complex 1 shows a one-dimensional anionic copper-malonate moiety connected by the malonate bridge, whereas complex 2 is a mononuclear one. For both the complexes, auxiliary ligands are attached with the Cu-malonate moiety through various noncovalent interactions. Optical band gap, electrical conductivity, and photosensitivity of complexes 1 and 2 were measured, but the values of electrical parameters of the complexes significantly differ from each other. However, the magnitudes of electrical parameters increase several times for both the complexes when they are exposed under visible light, though the values of light sensing parameters of complex 1 were found to be higher than those of complex 2. Density functional theory calculations for complex 1 were carried out to support the experimental result.

2-氨基-4-甲基吡啶和 2-氨基嘧啶配体对丙二酸-Cu(II) 系统的影响：通过超分子相互作用和光响应特性的见解。
合成了两种带有2-氨基-4-甲基吡啶（配合物1）和2-氨基嘧啶（配合物2）辅助配体的丙二酸铜配合物，并建立了它们的单晶X射线衍射结构。辅助配体的变化在本发明的复合物中表现出显着的结构变化。配合物 1 显示通过丙二酸桥连接的一维阴离子丙二酸铜部分，而配合物 2 是单核部分。对于这两种配合物，辅助配体通过各种非共价相互作用与丙二酸铜部分连接。测量了配合物1和2的光学带隙、电导率和光敏性，但配合物的电学参数值彼此存在显着差异。然而，尽管配合物1的光传感参数值高于配合物2，但当它们暴露在可见光下时，两种配合物的电学参数的大小都增加了数倍。配合物1的密度泛函理论计算进行以支持实验结果。
