配体

配体ligand,也称为配基)是一个化学名词,表示可和中心原子(金属或类金属)产生键结的原子、分子和离子。一般而言,配体在参与键结时至少会提供一个电子。配体扮演路易士碱的角色。但在少数情况中配体接受电子,充当路易斯酸。

在有机化学中,配体常用来保护其他的官能团(例如配体BH3可保护PH3)或是稳定一些容易反应的化合物(如四氢呋喃作为BH3的配体)。中心原子和配基组合而成的化合物称为配合物。

金属及类金属只有在高度真空的环境,可以以气态、不受和其他原子键结的条件存在。除此以外,金属和类金属都会和其他原子以配位或共价键的方式键结。络合物中的配体主宰了中心金属的的活性,而中心金属的活性也受配体本身被替换的速度、配体的活性等因素影响。在生物无机化学、药物化学、均相催化及环境化学等领域中,如何选择配体都是个重要的课题。

Ligand 配体

Cobalt complex HCo(CO)4 with five ligands
Metal–EDTA complex, wherein the aminocarboxylate is a hexadentate chelating ligand.
Cobalt(III) complex containing six ammonia ligands, which are monodentate. The chloride is not a ligand.

In coordination chemistry, a ligand is an ion or molecule (functional group) that binds to a central metal atom to form a coordination complex. The bonding between metal and ligand generally involves formal donation of one or more of the ligand's electron pairs. The nature of metal–ligand bonding can range from covalent to ionic. Furthermore, the metal–ligand bond order can range from one to three. Ligands are viewed as Lewis bases, although rare cases are known to involve Lewis acidic "ligand."
