Abstract
Mazkur ishda 2-merkaptoyantar kislota va ikki valentli nikel (Ni(II)) ioni asosida olingan kompleks birikmaning sintezi, tuzilishi, kvant-kimyoviy hisob-kitoblari hamda spektroskopik xossalari o‘rganildi. Dastlabki ligand sifatida 2-merkaptoyantar kislota ishlatildi. Ni(II) atsetatning 2-merkaptoyantar kislota bilan o‘zaro ta’siri asosida kompleks birikma sintez qilindi. Olingan kompleks birikmaning tuzilish xususiyatlarini aniqlash maqsadida kvant-kimyoviy hisoblashlar amalga oshirildi hamda molekulyar tuzilishi, elektron zichligining taqsimlanishi va global kimyoviy reaktivlik parametrlari tahlil qilindi. Shuningdek, kompleks birikmaning IQ spektri dastlabki ligand spektri bilan taqqoslanib, karboksil va tiol funksional guruhlariga tegishli tebranish chastotalaridagi o‘zgarishlar asosida ligandning Ni(II) ioniga koordinatsiyalanish xususiyatlari baholandi. Olingan natijalar asosida 2-merkaptoyantar kislotaning Ni(II) ioni bilan kompleks birikma hosil qilishdagi koordinatsion xususiyatlari va kompleksning ehtimoliy tuzilishi haqida xulosa qilindi.References
