KOBALT(II) XLORIDINING 2-AMINO-5-XLORBENZOKSAZOL LIGANDI BILAN HOSIL QILGAN KOMPLEKS BIRIKMANI SPEKTROSKOPIK TAHLILI.
##submission.downloads##
Ushbu tadqiqotda kobalt(II) xlorid tuzining 2-amino-5-xlorbenzoksazol ligandi bilan etanoli muhitda (1:2 molyar nisbatda)
[CoL2Cl2] tarkibli yangi koordinatsion birikmasini maqsadli sintez qilish usuli ishlab chiqildi (reaksiya unumi 76%, Tsuyuq=115-
117C. Sintez qilingan kompleksning tarkibi, tuzilishi va fizik-kimyoviy xossalari IQ-spektroskopiya, termik tahlil (TGA/DTA)
hamda skanerlovchi elektron mikroskopiya va energodispersion rentgen spektroskopiyasi (SEM-EDS) usullari yordamida har
taraflama oʻrganildi.IQ-spektral tahlil natijalariga koʻra, azometin C=N guruhining valent tebranish chastotasi erkin ligandga
nisbatan quyi chastotali sohaga siljiganligi aniqlandi, bu esa ligandning markaziy Co(II) ioni bilan endotsiklik azot atomi orqali
koordinatsiyalanganligini isbotlaydi. Termik tahlil (TGA/DTA) maʼlumotlari kompleksning 200 C gacha termik barqarorligini
hamda uning parchalanishi koʻp bosqichli xarakterga ega ekanligini koʻrsatdi. SEM-EDS mikroanaliz natijalari esa namunada barcha elementlarning (Co, Cl, C, N, O) bir jinsli taqsimlanishini va mexanik aralashma emas, balki yangi kompleks birikma
ekanligi tasdiqladi.
