那位化学英语高手帮忙翻译下论文，用翻译软件翻译得很不通顺 谢谢帮忙

The single-crystal X-ray diffraction analysis reveals that each Ni(II) ion is six-coordinate with four oxygen atoms and two nitrogen atoms to give a octahedral geometry. The Ni-O distances range from 2.0463(19)to 2.1673(15) Å and the Ni-N distances are 2.0258(17) and 2.0415(18) . In the structure, each carboxylate ligand serving as a biconnector through its two carboxyl moieties bridges two Ni(II) ions to form an infinite 1D chain view along the b axis, demonstrating the helical chain structure along a crystallographic 21 screw axis with a pitch of 15.039 Å.

Answer 1

单晶X射线稍微分析显示，每个二价的Ni离子和四个氧原子以及2个氮原子配位，从而形成一个八角型。 NI-O键长处在为、2.0463(19)to 2.1673(15) ? ， Ni-O键长处在2.0258(17) and 2.0415(18) 之间。

根据这个结构，每个羧酸基起到了一个双联接的作用，两头联接两个二价的Ni离子，从B轴看，形成了一个一维的无限长的链。
该螺旋链从结晶方向有21个螺纹，螺距是15.039A
