摘要
制备了三种不同结晶形式的烟酰胺核苷氯(NR-Cl)，即A型、B型和C型。形式A和形式B是无水形式的真多晶型，而形式C是甲醇酸溶剂化物形式的伪多晶型。建立了三种晶型之间的相对晶型稳定性关系，发现B型晶型相对于a型(1.512 Mg/m3, 119℃)具有更高的晶密度(1.591 Mg/m3)和更高的熔化/分解温度(123℃)，是最稳定的晶型。通过单晶x射线衍射分析确定了形式B(正交P212121空间群，a = 7.0008(11) Å， B = 9.6465(15) Å， c = 17.971(3) Å， V = 1213.7(3) Å3, Z = 4)的晶体结构。摘要报道了最稳定的烟酰胺核苷氯(NR-Cl)多晶型的晶体结构。
Polymorphism of Nicotinamide Riboside Chloride and Crystal Structure Determination of the Most Stable Crystalline Form
Three crystalline forms of nicotinamide riboside chloride (NR-Cl), namely Form A, Form B and Form C, were prepared and characterized. Form A and Form B are true polymorphs of anhydrous forms, while Form C is a pseudo-polymorph of a methanolate solvate form. The relative polymorphic stability relationship among these three crystalline forms was established, and Form B was found to be the most stable form with a higher crystal density (1.591 Mg/m3) and a higher melting/decomposing temperature (123 °C) compared to that of Form A (1.512 Mg/m3 and 119 °C). The crystal structure of Form B (orthorhombic P212121 space group, a = 7.0008(11) Å, b = 9.6465(15) Å, c = 17.971(3) Å, V = 1213.7(3) Å3, Z = 4) was determined by single crystal X-ray diffraction analysis.
Index Abstract
The crystal structure of the most stable polymorph of nicotinamide riboside chloride (NR-Cl) is reported.
