A series of bis(pyrrolidone) and ε-caprolactam co-crystals of boricacid and 1,4-phenylenediboronic acid are reported. The high polarity of the lactam carbonyl group is highly complementary to the boronic acid hydrogen bond donor functionalities and co-crystals are based on cyclic boronic acid tape motifs, including an unusual donor–donor motif, with strong perpendicular interactions to the lactam
The present application relates to a method for preparing compounds of the formula I in which, in a first step, γ-butyrolactone is reacted with diamines of the formula II to form bisamides of the formula III, with the amide function of the bisamides of the formula III then undergoing partial or complete catalytic hydrogenation in step II) to form bispyrrolidine compounds of the formula I.

reaction in methanol gives a 1 : 1 complex, namely [Na2(μ-1)2(MeOH)2](PF6)2 (6). Use of tetraphenyl borate as a less coordinating counter ion gives [Na2(1)2(H2O)4](BPh4)2 (7) and [Na2(1)4](BPh4)2 (8). Two potassium complexes have also been isolated, a monomer [K(1)2]PF6 (9) and a cyclic tetramer [K4(μ4-H2O)2(μ-1)4](PF6)4 (10). The structures illustrate the highly polar nature of the amide carbonyl moiety within

Povidone-iodine is a widely used antiseptic and on the World Health Organization’s List of Essential Medicines. We report the X-ray crystal structure of a two-monomer unit model compound showing that the structure of povidone-iodine comprises protonated pyrrolidone units linked by intermolecular hydrogen bonds along with triiodide anions. We also report an unusual example of a system exhibiting both a cocrystal and coamorphous form in a halogen bonded lactam model compound with diiodotetrafluorobenzene.
聚维酮碘是一种广泛使用的消毒剂,已被列入世界卫生组织的基本药物清单。我们报告了一种双单体单元模型化合物的 X 射线晶体结构,显示聚维酮碘的结构由质子化的吡咯烷酮单元和三碘阴离子组成,吡咯烷酮单元通过分子间氢键连接。我们还报告了一个不寻常的例子,即一个卤素键内酰胺模型化合物与二碘四氟苯的体系同时呈现出共晶和共晶形式。
