[求助] 今天翻译论文发现自己的英文烂大街了,第三次求助

The geometry around this pentacoordinated Zn atom is distorted square pyramid. The Zn(1)AO(1) bond distance (1.972(4) Å and Zn(1)-O(3) bond distance (1.977(4) Å are slightly shorter than that of Zn(2)-O(5) (1.988(4))  and obviously shorter than that of Zn(2)-O(2) (2.152(4) Å and Zn(2)-O(4)ii (2.151(4) Å. The Zn(2)AN(1) bond distance (2.023(4)) and Zn(2)AN(2)ii bond distance (2.019(4) Å are slightly shorter than that ZnAN bond distances reported in the literature , and significantly shorter than other ZnAN bond distances (2.148(3) and 2.156(3) Å reported in the literature . In each ligand PIDC, the imidazole ring and pyridyl ring are almost vertical with a dihedral angle of 76.6°. It is worth noting that the PIDC in 1 adopts a new μ4-kN, O:kN’, O’:kO’’, 0’’’:kN’’’coordination mode (Scheme 1) to bridge four Zn(II) atoms in bis-N,O-chelating, O,O’-chelating, and monodentate fashions. The overall structure of 1 is a two-dimensional framework, as illustrated in Fig. 2. Moreover, the hydrogen bond (Table 4) occurring at O5--H5A. . .O3i and O5--H5B. . .O1ii give rise to a three-dimensional framework.

对于这个5配位的Zn原子而言,它的配位环境为一个扭曲的八面体结构(square pyramid是正四角锥柱的意思,就相当于把两个金字塔形状的物体,它们的四边形地面彼此黏在一起而形成的物体,担不一定是正八面体),Zn(1)AO(1)键的键长为1.972(4)埃,Zn(1)-O(3)键键长为1.977(4)埃,这两者的键长都要比Zn(2)-O(5)的1.988(4)埃的键长要稍短,而相比Zn(2)-O(2)键和Zn(2)-O(4)键【键长分别为2.152(4)埃和2.151(4)埃】,这两者的键长则明显要更短一些。对于Zn(2)AN(1)键【键长为2.023(4)埃】和Zn(2)AN(2)ii键【键长为2.019(4)埃】,两者键长与本文献中所报告的ZnAN键长相比要稍短,而与其他文献中所报告的ZnAN键键长【(2.148(3) 埃及2.156(3)埃 】相比,则会极为明显的要短很多。在每个PIDC配体中,咪唑环和吡啶环之间的角度为76.6度,几乎垂直。值得注意的是,再配合物1中,PIDC配体采取的配位模式为一个新的μ4-kN, O:kN’, O’:kO’’, 0’’’:kN’’’配位模式(如图表1所示),接住这种配位模式,,PIDC配体将四个Zn(二价)分别以 两个N,O螯合的形式,一个O,O螯合的形式及一个单齿配合的形式配位成型。配合物1的整体结构是一个二维的框架,(如图2所示)。除此之外,在O5--H5A. . .O3i之间出现的氢键和在O5--H5B. . .O1ii之间出现的氢键最终促成了改配合物的三维结构(意思就是说二维结构之间通过这些氢键相连最终成为三维结构)。
