對晶體鍵長鍵腳描述的一段話,自己翻譯成英文,求大家給改一下

配合物1中的N3-為EO橋聯(lián),橋聯(lián)鍵長分別為Mn(4)-N(5)=2.323(8) Å,Mn(1)-N(5) 2.474(6) Å,橋角81.6度。由于N(5)對Mn(4)和Mn(1)離子都是軸向配位,所以出現(xiàn)了如此低的橋角。據(jù)作者所知,到目前為止這是疊氮橋聯(lián)配合物出現(xiàn)的的最低橋角,配合物1中的N3-離子幾乎成直線,相應(yīng)的角度為178.1(10)o(N(5)-N(6)-N(7))。配合物中的其它配位鍵長均在文獻報道的范圍內(nèi) 。分子中最短的兩個金屬間距離為2.9698(13) Å和3.1376(14) Å。由于大量晶格水的存在,使配合物分子間通過氫鍵連接形成了如圖5.4所示的三維網(wǎng)絡(luò)。 N3- in complex 1 is EO bridging and the bond distance are Mn(4)-N(5)=2.323(8) Å,Mn(1)-N(5)= 2.474(6) Å respectively, bridging angles is 81.6. The reason of appearing so low bridging angles is that N(5) is axial coordination with Mn(4) and Mn(1) ions. According to the authors , this is a minimum bridging angle of azide bridging complexes so far. N3- ion in complex almost a straight line and the corresponding angle is 178.1(N(5)-N(6)-N(7)). 寫不下去了…… |

| N3- in complex 1 is EO-bridged with bridging bond lengths of Mn (4)-N (5) = 2.323 (8) Å, Mn (1)-N (5) 2.474 (6) Å, and bridge angle 81.6 degrees. N (5) for Mn (4) and Mn (1) ions are axial ligands, that is why bridge angle is so low . To the authors' knowledge, this is the lowest bridge of azide bridging complexes and N3-ion in the complexes 1 is almost a straight line with angle of 178.1 (10) o (N (5) - N (6)-N (7)). The scope of the other ligand bond lengths in the complexes are similal to reported literature. Shortest intermolecular distance between two metal atom was 2.9698 (13) Å and 3.1376 (14) Å. Due to the presence of a large number of lattice water, the complex molecules hydrogen bonding formed a three-dimensional network shown in Figure 5.4. |
