Qhov twg hauv qab no yog Tetradent ligand?
Tetradentate ligands muaj nyob rau hauv cov xwm txheej hauv daim ntawv ntawm chlorophyll uas muaj cov tub ntxhais ligand hu ua chlorin, thiab heme nrog cov tub ntxhais ligand hu ua porphyrin. Lawv ntxiv ntau cov xim pom hauv cov nroj tsuag thiab tib neeg. Phthalocyanine yog ib qho khoom siv macrocyclic tetradentate ligand uas yog siv los ua xim xiav thiab ntsuab.
Yuav ua li cas yog bidentate ligands?
Bidentate ligands yog Lewis hauv paus uas pub ob khub ("bi") ntawm cov hluav taws xob rau cov hlau atom. Bidentate ligands feem ntau hu ua chelating ligands ("chelate" yog muab los ntawm Greek lo lus "claw") vim tias lawv tuaj yeem "lob" cov hlau atom hauv ob qhov chaw.
