[交流] 10金币求助一段英文翻译和一句话中文翻英文-----在线等急用

1.本文简要介绍了砷锑铋的化学性质并综述了近年来砷、锑、铋的配合物在抗癌抗菌抗肿瘤等生物活性方面的应用,展望了在该领域的应用前景。
    翻译为英文。
2.Both common oxidation states exhibit Lewis acidity (and the III state also shows Lewis basicity)in both cases resulting in complexes in which the group 15 atom’s outer electron count exceeds an octet. Although the traditional bonding model in such complexes invoked d-orbitals, the bonds are now more usually described in terms of delocalized 3-center-4-electron bonds, based upon sand p-orbitals. For the Lewis acid complexes of the III oxidation state, the concept of primary E-X bonding in the parent Lewis acid (EX3, E=As, Sb, or Bi; X=halide) and secondary bonds to the Lewis base, utilizing E–X б* as acceptor orbitals, is a useful approach. The primary/secondary bonding and the 3-center-4-electron bonds are not distinct models but may be shown to be variants of the same basic model。

1. This paper briefly introduced the chemical properties of arsenic, antimony and bismuth, reviewed applications of their complexes in anti-cancer and antibacteria, and prospected the application future in the field.

2. 两个一般的氧化态在两种情况下都显示有路易斯酸性(III态也表现出路易斯酸性)。这说明化合物的第15组原子的外层电子数超过了8个。尽管这种化合物的传统键合模型只调用d轨道,但在这里却往往描述为基于上层和p轨道的离域的3中心4电子键合模型。

相关知识有限,只能翻译这么多了。仅供楼主参考。
