Lus piav qhia luv luv:

Niobium (V) chloride, tseem hu ua niobium pentachloride, yog daj crystalline khoom. Nws hydrolyzes hauv huab cua, thiab cov qauv feem ntau muaj paug nrog me me ntawm NbOCl₃. Nws yog feem ntau siv los ua tus precursor rau lwm cov tebchaw ntawm niobium. NbCl₅ tuaj yeem ua kom huv los ntawm sublimation.

Daim ntawv thov

Niobium Chloride NbCl5 CAS 10026-12-7

Siv los tsim cov tshuaj chloro-aryloxide sib xyaw, xws li [Nb(OC6H3-2,6-i-Pr2)2Cl3]2, uas tsim pyridine los yog phosphine adducts nrog distorted rau-coordinate geometry.

Siv raws li Lewis acid catalyst hauv organic synthesis.

Niobium (V) chloride yog cov ua ntej hauv kev npaj cov ntshiab niobium, thiab ferroniobium. Nws yog siv los ua Lewis acid catalyst hauv organic synthesis hauv activating alkenes hauv cov tshuaj tiv thaiv carbonyl-ene thiab Diels-Alder cov tshuaj tiv thaiv.
