Solid-state vibrational spectroscopic investigation of cocrystals and salt of indomethacin. Abstract Knowledge and control of the solid forms of active pharmaceutical ingredients are important aspects of drug development in the pharmaceutical industry. In this paper, the process of the molecular self-assembly of saccharin cocrystals and the 2-amino-5-methylpyridine salt of indomethacin, in terms of the hydrogen…

Structural Studies and Cytotoxicity of Trimethyl(ferrocenylmethyl) ammonium Iodide Encapsulated in β-Cyclodextrin Abstract nclusion complexes that comprise β-cyclodextrin (β-CD) and trimethyl(ferrocenylmethyl)ammonium iodide (1) have been prepared by codissolution of the host and guest in ethanol/water, accompanied by either conventional heating at 40 °C for 26 h (to give 2) or microwave-assisted heating for 30 min (to…

1,3,5-Tris(bromomethyl)benzene. Abstract The asymmetric unit of the title compound, C9H9Br3, is composed of a single molecule. Two bromo substituents are located on one side of the plane of the aromatic ring and the third is on the opposite side, with the molecular unit exhibiting an approximate noncrystallographic Cs point group. The crystal structure is rich…

Inclusion of potassium 4,4 biphenyldicarboxylate into beta-cyclodextrin: the design and synthesis of an organic secondary building unit Abstract The paper describes a design strategy for the preparation of a novel inclusion compound (potassium 4,4′-biphenyldicarboxylate⊂β-CD) suitable for use in supramolecular chemistry. In the first step the chemical feasibility of such an inclusion compound was evaluated by…

Chemistry and Catalytic Activity of Molybdenum(VI)-Pyrazolylpyridine Complexes in Olefin Epoxidation. Crystal Structures of Monomeric Dioxo, Dioxo-mu-oxo, and Oxodiperoxo Derivatives. Abstract The dioxomolybdenum(VI) complexes [MoO2Cl2(PzPy)] (1) and [MoO2(OSiPh3)2(PzPy)] (5) (PzPy = 2-[3(5)-pyrazolyl]pyridine) were synthesized and characterized by vibrational spectroscopy, with assignments being supported by DFT calculations. Complex 5 was additionally characterized by single crystal X-ray diffraction….
