چکیده

۵،۵-دی‌متیل-۲-(۴-کلروفنوکسی)-۲-اکسو-۱،۳،۲-دی‌آزافسفرینان در سامانه بلوری تک میل گروه فضایی P21/c، با یک مولکول در واحد بی تقارن، متبلور می­شود. ساختار بلوری ترکیب با پراش پرتو ایکس و پرتو αK مس در دمای 95 کلوین تعیین شد. در این ترکیب، اتم فسفر در یک محیط چهاروجهی واپیچیده P(O)(O)N2 قرار دارد و حلقه C3N2P صورت‌بندی صندلی تغییر شکل یافته دارد. جهت‌گیری هم پیراصفحه­ای قطعه PONH مناسب برای تشکیل یک واحد تکراری حلقوی پیوند هیدروژنی  بین دو مولکول کنار هم است. انباشت سه بعدی فرامولکولی شامل برهم­کنش‌های H⋯O، H⋯H، H⋯Cl و H⋯π است. تحلیل سطح هیرشفلد، محاسبه‌های نقشه پتانسیل الکترواستاتیکی و چارچوب‌های انرژی برای توصیف برهم­کنش‌های بین‌مولکولی استفاده شد.

چکیده [English]

5,5-dimethyl-2-(4-chlorophenoxy)-2-oxo-1,3,2-diazaphosphorinane crystallizes in the monoclinic space group P21/c, with one molecule in the asymmetric unit. The crystal structure of the compound was determined at 95 K using X-ray diffraction with Cu radiation. In this compound, the phosphorus atom is within a distorted tetrahedral P(O)(O)N2 environment and the C3N2P ring adopts a twisted chair conformation. The synperiplanar (sp) orientation of the PONH fragment is suitable for the formation of an  hydrogen-bond motif between two adjacent molecules. The three-dimensional supramolecular assembly includes H···O, H···H, H···Cl, and H···π contacts. Hirshfeld surface analysis, electrostatic potential map and energy frameworks calculations were used to illustrate intermolecular interactions.
