过渡金属的性质
Transition metals are defined as those elements that have partially filled d orbitals. As shown in Figure 1, the d-block elements in groups…
配位化合物和命名法
In most main group element compounds, the valence electrons of the isolated atoms combine to form chemical bonds that satisfy the octet rule. For…
金属配体键
The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain…
配位数和几何结构
For transition metal complexes, the coordination number determines the geometry around the central metal ion. Table 1 compares coordination numbers…
结构性异构
Isomerism in Complexes Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can…
立体异构
Isomers are different chemical species that have the same chemical formula. Transition metal complexes often exist as geometric isomers, in which…
价键理论
Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from…
晶体场理论 - 八面体络合物
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons…
晶体场理论 - 四面体和平面四边形络合物
Tetrahedral Complexes Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes…
颜色和磁性
Color in Coordination Complexes When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals.…
制备SNS钴(II)针质模型复合物肝酒精脱氢酶
Chemical model complexes are prepared to represent the active site of an enzyme. In this protocol, a family of tridentate pincer ligand precursors…
作为一种工具来区分立体异构体的库仑爆炸成像
This article shows how the COLTRIMS (Cold Target Recoil Ion Momentum Spectroscopy) or the "reaction microscope" technique can be used to distinguish…
配体介导成核与钯金属纳米粒子的生长
The size, size distribution and stability of colloidal nanoparticles are greatly affected by the presence of capping ligands. Despite the key…
