Journal ArticleDOI
Crystal and molecular structures of twelve salts from isopropylamine and different organic acids
TL;DR: The role of weak and strong non-covalent interactions in the crystal packing is ascertained in this paper, where isopropylamine derived supramolecular complexes are characterized.

Substituent-Dependent Formation of Supramolecular Aggregates of 6-Hydroxy-trans-3-hexenoic Acids in the Solid State
Hans Christian Strauch,Thomas Rinderknecht,Gerhard Erker,Roland Fröhlich,Elina Wegelius,Frank Zippel,Stephanie Höppener,Harald Fuchs,Lifeng Chi +8 more
TL;DR: The structural features of the molecular assemblies that are formed by intermolecular hydrogen bonding of compounds 2-4 in the solid state are selectively controlled by the size and favored conformations of the spiro-anellated carbocyclic rings at C6 of the 6-hydroxy-trans-3-hexenoic acid carbon chain this paper.
Molecular incorporation of benzoic acid and salicylic acid into BEA zeolites
Takashi Tomizawa,Aya Watanabe,Waree Limwikrant,Yuichi Tozuka,Kunikazu Moribe,Keiji Yamamoto,Shoji Takamatsu,Shinichiro Nakajima,Dan Liu,Xueping Fei,Siling Wang,Tongying Jiang,Desen Su +12 more
TL;DR: In this article, the authors developed new solid dispersions of benzoic acid (BA) and salicylic acid (SA) using Beta zeolite and investigated the molecular states of the drugs in the pores.

Intensity distribution in the fluorescence low-frequency mode progressions of the “slightly” asymmetric hydrogen bonded AHB fragment
TL;DR: In this paper, a model of the potential energy surface (PES) of the asymmetric hydrogen-bonded OHO fragment is used for treatment of the intensity distribution in the fluorescence low-frequency mode progressions (LFMPs) of systems governing excited state proton transfer.

Crystal and molecular structure of methyl-3,4-dideoxy-3-(salicylidenylamino)-α- d - erythro -pentopyranoside
R. A. Palmer,H. T. Palmer +1 more
TL;DR: The crystal structure of methyl-3,4-dideoxy-3-(salicylidenylamino)-α-d-erythro-pentopyranoside has been determined by vector verification and successive Fourier syntheses, and refined by full-matrix least-squares calculations toR = 0.063 for 596 observed reflections as discussed by the authors.

Crystallographic least squares refinement program for the ibm 704
W.R. Busing,H.A. LEvy +1 more
TL;DR: OR XLS 1-5 as discussed by the authors is a program for structure factor calculation and for the least squares refinement of crystal structures using x-ray or neutron diffraction data, and it is divided into five segments, and the purpose of each is briefly described.
