Kuriy(III) xlorid yoki kuriy trixlorid — CmCl₃ kimyoviy formulasiga ega bo‘lgan aktinoid kimyoviy birikma.

Tuzilishi

Kuriy(III) xlorid 9 koordinatali uch qopqoqli trigonal prizmatik geometriyaga ega.^[1]

Sintez

Kuriy(III) xloridni 400–600 °C haroratda vodorod xlorid gazining kuriy dioksid, kuriy(III) oksid yoki kuriy(III) oksixlorid bilan reaksiyasi orqali olish mumkin:

CmOCl + 2HCl → CmCl₃ + H₂O

Uni metallik kuriyning suyultirilgan xlorid kislotada eritilishi orqali ham olish mumkin:^[2]

2Cm + 6HCl → 2CmCl₃ + 3H₂ in H₂O

Bu usul hosil bo‘lgan birikmaning suvli eritmada davom etadigan gidroliz va gidratlanish jarayonlari bilan murakkablashadi, bu esa sof mahsulot olishni qiyinlashtiradi.

Uni kuriy nitridining kadmiy xlorid bilan reaksiyasi orqali ham olish mumkin:^[3]

2 CmN + 3 CdCl₂ → 2 CmCl₃ + Cd₃N₂
