Sulphate ion tuaj yeem ua raws li ligand txuas los ntawm ib qho pa oxygen (monodentate) lossis los ntawm ob lub pa oxygen raws li chelate lossis tus choj. Ib qho piv txwv yog lub complex [Co(en)2(SO4) +Br − los yog cov hlau nruab nrab PtSO4(P(C6H5)3)2 qhov twg cov sulfate ion ua haujlwm ua ib lub ligand.
piv txwv ntawm bidentate ligand yog dab tsi?
Bidentate ligands muaj ob lub atoms pub dawb uas tso cai rau lawv khi rau lub hauv paus hlau atom lossis ion ntawm ob lub ntsiab lus. Piv txwv ntawm bidentate ligands yog ethylenediamine (en), thiab oxalate ion (ox).
YPuas pyridine yog bidentate ligand?
Tus pyridine derivative muaj peev xwm ua raws li bidentate ligand, xws li picolinic acid, nyiam ua kom muaj kev sib koom tes ntau dua. Ib tug xov tooj zoo ntawm complexes paub nrog ntau yam hloov pauv pyridines. Cov complexes paub nyob rau hauv +1 thiab + 3 xeev ntawm Sc thiab Y.
Puas yog dej yog bidentate ligand?
Dej yog hom monodentate ligand vim nws muaj cov pa oxygen uas muaj ib khub ntawm electrons. Txawm li cas los xij nws tuaj yeem zoo li dej yog bidentate vim tias muaj ob leeg ib leeg ntawm electrons tab sis bidentate ligand yuav tsum muaj ob qho sib txawv pub atoms. Yog li, cov lus teb yuav yog, yog dej yog ligand.
YPuas yog sulphate uas tsis muaj zog ligand?
Thawj thiab cia siab tias yuav pom tseeb ua ntej: sulphate ions ua daim ntawv (tsis muaj zog) kev sib koom ua kerau cov chaw hlau thiab yog li los ntawm kev txhais ua rau qee qhov d orbital splitting.
