通过水热反应，合成了一种2-(4-吡啶基)-苯并咪唑、对硝基苯甲酸及锌(Ⅱ)三元配合物.并对该配合物的结构进行了测定，发现该配合物属于三斜晶系,P-1点群，晶胞参数为a=0.7902(8)nm,b=1.3277(13)nm,c=1.7837(17)nm；α=99.953°(18),β=94.666°(16),γ=90.354°(16).每个锌离子周围有两个对硝基苯甲酸及两个2-(4-吡啶基)-苯并咪唑；其中两个对硝基苯甲酸分别以一个羧基氧原子，两个2-(4-吡啶基)-苯并咪唑分别以吡啶环上的氮原子和锌离子中配位，形成四面体结构.
通過水熱反應，閤成瞭一種2-(4-吡啶基)-苯併咪唑、對硝基苯甲痠及鋅(Ⅱ)三元配閤物.併對該配閤物的結構進行瞭測定，髮現該配閤物屬于三斜晶繫,P-1點群，晶胞參數為a=0.7902(8)nm,b=1.3277(13)nm,c=1.7837(17)nm；α=99.953°(18),β=94.666°(16),γ=90.354°(16).每箇鋅離子週圍有兩箇對硝基苯甲痠及兩箇2-(4-吡啶基)-苯併咪唑；其中兩箇對硝基苯甲痠分彆以一箇羧基氧原子，兩箇2-(4-吡啶基)-苯併咪唑分彆以吡啶環上的氮原子和鋅離子中配位，形成四麵體結構.

Through the hydrothermal synthesis techniques, a zinc(Ⅱ) compound was synthesized based on 2-(Pyridin-4-yl)-1H-Benzo[d]imidazole and p-nitrobenzoic acid. And the structure of the complexes were determined by X-ray single crystal diffraction. The crystal belongs to Triclinic system and P-1space group. The parameters of the crystal cell for the compound are a=0.7902(8)nm, b=1.3277(13)nm, c=1.7837(17)nm. α=99.953°(18),β=94.666°(16), γ=90.354°(16). The zinc(Ⅱ) is coordinated with two nitrogen atoms of two 2-(Pyridin-4-yl)-1H-Benzo[d]imidazole molecule, and two oxygen atoms from two p-nitrobenzoic acid molecule, generating a distorted Tetrahedron coordination geometry.
