中心离子 meaning in English
center ion
central ion
Examples
- The number of ligands attached to the central ion is called the coordination number .
同中心离子连接的配位体，数目称为配位数。 - And tg - dsc . 3 . n , n ' - disalicylidenedianilines and its transition metal complexes of nicl2 6h2o are synthesized by liquid and solid state reaction at room temperature , and their thermochromism are investigated by ir , far i . r
文中的配合物就是其中之一，中心离子是与c = n双键的n原子以及苯环上邻位的羟基的氧原子同时进行配位的。 - Metallophalocyanines ( mpcs ) are a kind of centrosymmetric planar organo - metallic molecules with an extensively delocalized two dimensional conjugated - electron system which show a relatively large third order optical nonlmearity , varying upon central metal atom substitution and other factors . other interesting properties of this molecule and many of its derivative products are their versatility , architectural flexibility and high environmental stability , which are very important requirements to implement photo - electronic applications
