[求助] 一段關(guān)于晶體結(jié)構(gòu)分析的英文文獻翻譯

圖片和英文是一樣的，主要是怕粘貼過來不準(zhǔn)所以附了一張圖片
The coordination environments about all of the d9 Cu2+ ions are the best considered as ‘4+2’ [CuO4N2] Jahn-Teller distorted octahedral [12]. The N(1), N(2), O(2) and O(3) occupy the equatorial positions, whereas O(1) and O(7) occupy the axial positions. The four equatorial atoms around the copper atom are almost square planar with maximum deviations from the O(2), N(1), O(3) and N(2) mean planes of -0.1421(10)o at O(2) and -0.1436(10)o at O(3). The Cu(1)–N(1) and Cu(1)–N(2) distances are 2.0499(18) Å and 2.0487(17) Å2.0499(18) Å, respectively (see Table 2). The axial Cu(1)-O(1) distance of 2.2178(17) Å is significantly longer than the equatorial Cu(1)-O(2) and Cu(1)-O(3) distances of 1.9815(18) Å and 1.9640(19) Å, respectively. The shorter Cu(1)-O(1) bonds located in the cis position relative to the Cu(1)-O(7) bond of 2.668(2) Å is attributed to the Jahn-Teller effect. This value is slightly shorter than that of 2.688(2) Å found in previous work [4]. The Jahn-Teller effect gives a long coordinating S-O bond compared to the terminal S-O bonds of the pendant sulfate anion. This sulfate group acts as a monodentate ligand in which sulfur atom of the sulfate anion is approximately tetrahedral geometry. Its bond lengths and angles are within the range of values found in another similar sulfate anion compounds and previous reports [4,5,10].

‘4+2’ [CuO4N2] Jahn-Teller扭曲八面體（12）結(jié)構(gòu)最好的解釋了所有d9 Cu2+離子的配位環(huán)境. N(1), N(2), O(2)和O(3)占據(jù)著赤道位置，O(1) 和O(7)占據(jù)著軸位置。銅原子周圍的4

個赤道原子幾乎呈正方平面， O(2) 和 O(3)到O(2), N(1), O(3) 和 N(2)平均平面的最大誤差分別是-0.1421(10)o 和-0.1436(10)o 。Cu(1)–N(1) 和Cu(1)–N(2)的距離分別是2.0499(18) Å 和2.0487(17) Å2.0499(18) Å（見表格2）。Cu(1)-O(1)軸距（2.2178(17) Å ）比赤道平面Cu(1)-O(2)（1.9815(18) Å ）和 Cu(1)-O(3) （1.9640(19) Å）距離明顯大很多。與 Cu(1)-O(7)鍵長（2.668(2) Å）相比相對較短的處于順式位置的Cu(1)-O(1) 鍵可能受到了Jahn-Teller效應(yīng)的影響。該值比此前報道的 2.688(2) Å略小【4】。與硫酸根陰離子S-O鍵相比，Jahn-Teller效應(yīng)使得S-O配位鍵變長。作為單齒配體的硫酸根基團中硫原子大致呈四面體狀。鍵長與角度與之前其他文獻報道里硫酸根陰離子化合物的數(shù)值接近【4.5.10】。
