A monoclinic polymorph of cysteamine hydrochloride

Abstract

Chlorure de 2-mercaptoéthan-aminium), C(2)H(8)NS(+)·Cl(-), le sel d'hydrochlorure de cystéamine, contrairement au polymorphe triclinique précédemment rapporté [Kim et al. (2002▶). Polyhedron, 21, 225-228], cristallisé dans le système cristallin monoclinique. Dans le cristal, les cations cystéaminium sont liés aux anions chlorure par l'intermédiaire d'une liaison hydrogène S-H Cl et de trois liaisons hydrogène N-H Cl. Des réseaux bidimensionnels en forme de dalle sont formés, qui sont empilés dans [100]. Cet arrangement est similaire à celui observé chez le polymorphe triclinique.

cloruro de 2-mercaptoetano-aminio), C(2)H(8)NS(+)·Cl(-), la sal de hidrocloruro de cisteamina, en contraste con el polimorfo triclínico previamente informado [Kim et al. (2002▶). Polyhedron, 21, 225-228], cristalizado en el sistema cristalino monoclínico. En el cristal, los cationes de cisteaminio están unidos a los aniones cloruro a través de un enlace de hidrógeno S-H Cl y tres N-H Cl. Se forman redes bidimensionales en forma de losa, que se apilan en [100]. Esta disposición es similar a la observada en el polimorfo triclínico.

2 - ميركابتو إيثان- أمينيوم كلوريد)، C(2) H (8) NS (+) ·Cl (-)، ملح كلوريد الهيدروكلوريد للسيستامين، على النقيض من تعدد الأشكال التريكليني الذي تم الإبلاغ عنه سابقًا [Kim et al. (2002▶). متعدد السطوح، 21، 225-228]، تبلور في نظام الكريستال أحادي الميل. في البلورة، ترتبط كاتيونات السيستيامينيوم بأنيونات الكلوريد عبر رابطة هيدروجينية واحدة من نوع S - H - Cl وثلاث روابط هيدروجينية من نوع N - H - Cl. يتم تشكيل شبكات تشبه البلاطة ثنائية الأبعاد، والتي يتم تكديسها في [100]. هذا الترتيب مشابه للترتيب الذي لوحظ في الشكل الثلاثي.

2-mercaptoethan-aminium chloride), C(2)H(8)NS(+)·Cl(-), the hydro-chloride salt of cysteamine, in contrast to the previously reported triclinic polymorph [Kim et al. (2002 ▶). Polyhedron, 21, 225-228], crystallized in the monoclinic crystal system. In the crystal, the cysteaminium cations are linked to the chloride anions via one S-H⋯Cl and three N-H⋯Cl hydrogen bonds. Two-dimensional slab-like networks are formed, which are stacked in [100]. This arrangement is similar to that observed in the triclinic polymorph.
