Abstract
Ushbu maqolada diakvabis(5-metiltiazol-2-karboksilato-κ2N,O) kobalt (II) koordinatsion birikmasining sintezi, kristall tuzilishi va Hirshfeld yuza tahlili oʻrganilgan. Birikma kobalt(II) asetat tetrahidrati (0,249 g, 1,0 mmol) va 5-metiltiazol-2-karboksilik kislota (0,286 g, 2,0 mmol) asosida suv-etanol aralashmasida xona haroratida sintezlangan boʻlib, hosildorlik 80% ni tashkil etgan. Kristall tuzilishi monoklinik P2₁/c fazoviy guruhda aniqlangan, markaziy kobalt(II) ioni buzilgan oktaedr muhitda joylashgan: Co–N 2,126(6) Å, Co–O (karboksilat) 2,133(5) Å, Co–O (suv) 2,062(4) Å. Kristall struktura Cu Kα nurlanish yordamida Xcalibur Ruby difraktometrida yechilgan, R₁ = 0,1029, wR₂ = 0,2800. Hirshfeld yuza tahlili CrystalExplorer 17 dasturida oʻtkazilgan boʻlib, yuza maydoni 325.55 Ų, hajmi 357.67 ų, boʻshliqlar hajmi 71.29 ų ni koʻrsatgan. Asosiy intermolekulyar oʻzaro taʼsirlar: H···O/O···H (32.7%), H···H (28.9%), H···S/S···H (17.6%). Bu natijalar vodorod bogʻlanishlari va van-der-Vaals kuchlarining kristall barqarorligidagi rolini ochib bergan
