Abstract

Two novel Co(II) and Ni(II) complexes Co(dpza)₂ (1) and Ni(dpza)₂ (2) (Hdpza is 2,2-di(1H-pyrazol-1-yl)acetic acid) were successfully synthesized via solvothermal method. The two complexes namely, 1 and 2 are isostructural exhibiting lantern-shaped configurations as illustrated by the structural analysis. The structures of the two complexes have been determined by single-crystal X-ray diffraction, FT-IR, and TGA. Magnetic property of 1 in the 2–300 K also has been investigated which displays dominant ferromagnetic behavior. Hirshfeld surface analysis reveals that the main interactions for complex two are O···H/H···O and H···H contacts.

摘要

两种新型 Co(II) 和 Ni(II) 配合物 Co(dpza) ₂ ( 1 ) 和 Ni(dpza) ₂ ( 2 )（Hdpza 是 2,2-di(1 H -pyrazol-1- yl )acetic acid）采用溶剂热法成功合成。如结构分析所示，这两个复合物即1和2是等结构的，呈现出灯笼形配置。这两种配合物的结构已通过单晶 X 射线衍射、FT-IR 和 TGA 确定。磁性1在 2-300 K 范围内也进行了研究，显示出主要的铁磁行为。Hirshfeld表面分析表明，络合物二的主要相互作用是O···H/H···O和H···H接触。
