چکیده

با استفاده از واکنش کلرید کبالت(II) شش آبه و لیگاند 4-آمینو-5،3-بیس(3-پیریدیل)-4،2،1-تری‌آزول (L) در سامانه حلال متانول/استونیتریل و روش تبخیر آرام حلال، بلور‌های مکعبی شکل و بنفش‌رنگ ترکیب (1) [CoL2Cl2]n تشکیل شدند. بررسی ساختار بلوری این ترکیب بیانگر تبلور آن در سامانه بلوری تک میل با گروه فضایی P21/c است. برای شناسایی این ترکیب و تعیین ساختار آن از روش­های پراش پرتوی ایکس تک‌بلور، پراش پرتوی ایکس پودر، تجزیه عنصری، طیف ­نجی فروسرخ و تحلیل سطح هرشفلد استفاده شد. براساس نتایج ساختاری به‌دست آمده از داده‌های پراش پرتوی ایکس تک‌بلور، این ترکیب دارای الگوی ساختاری دوبعدی لوزی شکل است.

چکیده [English]

By Using the reaction of cobalt (II) chloride hexahydrate and 4-amino-3,5-bis(3-pyridyl)-1,2,4-triazole (L) ligand in methanol/acetonitrile solvent system and solvent slow evaporation method result in, purple-colored cubic-shaped crystals of compound [CoL2Cl2]n (1). The investigation of crystal structure of this compound indicates it was crystallized in the monoclinic crystal system and P21/c space group. The single-crystal X-ray diffraction, powder X-ray diffraction, elemental analysis, infrared spectroscopy, and Hirshfeld surface analysis have been used for identification of the compound and its crystal structure determination. According to the our structural information obtained from single-crystal X-ray diffraction data, this compound has a rhombic-shaped two-dimensional structural motif.
