四方锥

从晶体结构解析信息可知，[ZnCl2L2]2为氯桥联的双核配合物，属单斜晶系，空间群P21/c，是以Zn（Ⅱ）为中心的五配位的变形四方锥结构。

The results of crystal structure analysis showed that complex [ ZnCl2L2 ] 2 with chloro-bridged dinuclear zinc , crystallized in monoclinic system and P21 / c space group , in which Zn ( II ) ion was coordinated with five atoms , they formed distorted square pyramidal geometry .

在此序列和五配位四方锥构型基础上，解释了各氧多齿配体与TcO3＋的结合性质。

The coordination characters of TcO 3 + with multidentate oxygen donor ligands are rationalized by that sequence and the square pyramidal geometry of TcO 3 + complexes .

每个Cu离子的配位环境可以看做为一个扭曲的四方锥型结构。

The coordination of copper (ⅱ) ion can be seen as a distorted tetragonal pyramid .

每个中心Cu（Ⅱ）离子均处于五配位扭曲四方锥构型，配位原子分别来自于两个螯合的邻菲咯啉配体和一个己二酸根上的羧基氧原子。

Each Cu (ⅱ) center is pentacoordinated ( CuN_4O ) to two chelating phen ligands and a carboxylate oxygen from adipate , displaying a slightly distorted square-pyramid geometry .

紫外光谱研究表明：在生理pH条件下，随Fe（Ⅲ）-Zn（Ⅱ）-血清白蛋白体系浓度的增大，其配位中心发生从八面体构型到四方锥构型的转变。

With the increase of the concentration of the Fe (ⅲ) - Zn (ⅱ) - serum albumin system at molar ratio 1:1:1 , its coordination center changes from octahedron to square-pyramid .

簇合物的中心由10个四方锥的钒氧基元连接而成，上下二端分别与一个[B14O30（OH）2]20-相连接。

The clusters have a central band often square-pyramidal V-O vanadyl groups , which are capped top and bottom by two crown-like polyborate ligands of formula [ B14O30 ( OH ) 2 ] 20 - .

这六个配合物均为0D的配合物，其中只有7是五配位的四方锥构型，其余的配合物8-10都是六配位的八面体构型。

All the six complexes are with 0D structures , of which 8-10 are six-coordinated with octahedral configuration and only 7 is five-coordinated with square-pyramid configuration .

中心Cu离子分别与两个DPQ配体上的4个吡啶氮原子以及高氯酸根上的一个氧原子配位，其配位几何构型为理想四方锥。

The central Cu ~ ⅱ atom is penta-coordinated by four nitrogen donors of the pyridine rings of two DPQ and an oxygen atom of the perchlorate , and the coordination geometry of Cu ~ ⅱ could be considered as an ideal square-pyramidal environment .

结果表明：配合物中的金属均是五配位并采用扭曲的四方锥构型，但由于轴向上的配位原子以及大环配体的不同它们的堆积结构有较大差别。

The results show that : All metal ions have five coordinated atoms with distorted square-pyramidal configuration . The crystal packings of complexes are different because of their different axial donor atoms and macrocyclic ligands .
