Qhov sib txawv tseem ceeb ntawm homoleptic thiab heteroleptic complexes yog tias homoleptic complexes muaj cov ligands zoo tib yam txuas rau lub chaw hlau hos qhov heteroleptic complexes muaj tsawg kawg yog ib qho sib txawv ligand txuas rau lub chaw hlau ntawm lub complex.
Cov ntsiab lus homoleptic thiab heteroleptic complexes tuaj nyob rau hauv inorganic chemistry, qhov uas peb tham txog kev hloov hlau complexes. Ob hom kev sib txawv no sib txawv ntawm ib leeg raws li qhov tshwm sim ntawm ligands txuas rau lub chaw hlau.
Homoleptic Complexes yog dab tsi?
Homoleptic complexes yog cov tshuaj sib xyaw uas muaj cov ligands zoo tib yam txuas rau lub chaw hlau. Peb ntsib cov lus no hauv inorganic chemistry thaum tham txog kev hloov pauv hlau. Lub npe "homo-" yog hais txog "ib yam rau txhua tus".
Daim duab 01: Homoleptic Complex nrog Ob Lub Ligands Zoo sib xws txuas rau Tib Lub Chaw Hlau
Ib qho piv txwv zoo li no yog dialkyl magnesium complex uas muaj nyob rau hauv ib qho kev daws ntawm Grignard reagent hauv ether, muaj ob lub ether ligands txuas rau txhua qhov chaw magnesium. Lwm qhov piv txwv ntawm homoleptic complex yog trimethylaluminium hauv ether xws li THF. Cov complex no muaj peb pawg methyl txuas nrog lub hauv paus txhuas hlau ion nrog +3 tus nqi zoo. Ib yam li ntawd, triaryl lossis trialkyl borane yog homoleptic complexes.
Heteroleptic Complexes yog dab tsi?
Heteroleptic complexes yog cov tshuaj sib txuas uas muaj tsawg kawg ib qho sib txawv ligand txuas rau lub chaw hlau. Qee cov ligands uas tau koom nrog hauv kev hloov pauv hlau nyuaj xws li DMSO tuaj yeem khi nrog ob lossis ntau hom kev sib koom ua ke. Nyob rau hauv tas li ntawd, peb xav txog cov hlau complex ua homoleptic, muaj tsuas yog ib hom ligands nrog ntau hom kev sib koom ua ke.
Daim duab 02: Ib qho Heteroleptic Complex muaj tsib Ligands zoo ib yam thiab ib qho sib txawv Ligand
Ib qho piv txwv ntawm heteroleptic complex yog cob alt (III) complex, nrog plaub ammonia ligands thiab ob chloride ligands. Lub sij hawm polynuclear complex, ntawm qhov tod tes, txawv los ntawm lo lus heteroleptic complex vim hais tias polynuclear complexes yog cov hloov hlau complexes muaj ob los yog ntau tshaj hlau chaw nrog cov ligands. Txawm li cas los xij, nws tseem yog hom heteroleptic complex yog tias cov ligands txuas rau cov chaw hlau sib txawv ntawm ib leeg.
Qhov txawv ntawm Homoleptic thiab Heteroleptic Complexes yog dab tsi?
Cov ntsiab lus homoleptic thiab heteroleptic complexes tuaj nyob rau hauv cov inorganic chemistry uas peb tham txog kev hloov hlau complexes. Ob hom kev sib txawv no sib txawv ntawm ib leeg raws li qhov xwm ntawm ligands txuas rau lub chaw hlau. Qhov sib txawv tseem ceeb ntawm homoleptic thiab heteroleptic complexes yog tias homoleptic complexes muaj cov ligands zoo tib yam txuas rau lub chaw hlau, hos heteroleptic complexes muaj tsawg kawg yog ib qho sib txawv ligand txuas mus rau qhov chaw hlau ntawm lub complex. Tsis tas li ntawd, homoleptic complexes tsawg dua li cov heteroleptic complexes.
Hauv qab no yog cov lus qhia txog qhov sib txawv ntawm homoleptic thiab heteroleptic complexes.
Summary – Homoleptic vs Heteroleptic Complexes
Cov ntsiab lus homoleptic thiab heteroleptic complexes tuaj nyob rau hauv inorganic chemistry qhov twg peb tham txog kev hloov hlau complexes. Ob hom kev sib txawv no sib txawv ntawm ib leeg raws li qhov xwm ntawm ligands txuas rau lub chaw hlau. Qhov sib txawv tseem ceeb ntawm homoleptic thiab heteroleptic complexes yog tias homoleptic complexes muaj cov ligands zoo tib yam txuas rau lub chaw hlau hlau hos heteroleptic complexes muaj tsawg kawg yog ib qho sib txawv ligand txuas mus rau lub chaw hlau ntawm lub complex.
