Crystal structures and hydrogen bonding in the morpholinium salts of four phenoxyacetic acid analogues
The anhydrous salts morpholinium (tetra-hydro-2-H-1,4-oxazin-4-ium) phen-oxy-acetate, C4H10NO(+)·C8H7O3 (-), (I), morpholinium (4-fluoro-phen-oxy)acetate, C4H10NO(+)·C8H6 FO3 (-), (II), and isomeric morpholinium (3,5-di-chloro-phen-oxy)acetate (3,5-D), (III), and morpholinium (2,4-di-chloro-phen-oxy)acetic acid (2,4-D), C4H10NO(+)·C8H5Cl2O3 (-), (IV), have been determined and their hydrogen-bon...
متن کاملCrystal structures and hydrogen bonding in the proton-transfer salts of nicotine with 3,5-dinitrosalicylic acid and 5-sulfosalicylic acid
The structures of the 1:1 anhydrous salts of nicotine (NIC) with 3,5-di-nitro-salicylic acid (DNSA) and 5-sulfosalicylic acid (5-SSA), namely (1R,2S)-1-methyl-2-(pyridin-3-yl)-1H-pyrrolidin-1-ium 2-carb-oxy-4,6-di-nitro-phenolate, C10H15N2 (+)·C7H3N2O7 (-), (I), and (1R,2S)-1-methyl-2-(pyridin-3-yl)-1H-pyrrolidin-1-ium 3-carb-oxy-4-hy-droxy-benzene-sulfonate, C10H15N2 (+)·C7H5O6S(-), (II), are ...
متن کاملHydrogen-bonding patterns of two dihydroxylactone derivatives.
In the hydrogen-bonding networks of 8-hydroxy-5-hydroxymethyl-3,6-dioxatricyclo[6.3.1.0(1.5)]dodecan-2-one and 5,7-bis(hydroxymethyl)-3,6-dioxatricyclo[5.3.1.0(1.5)]undecan-2-one, both C11H16O5, layers and double strands, respectively, lead to the formation of chains connected by hydroxy-to-hydroxy contacts, where the hydroxymethyl group, present in both structures, acts as a donor. The seconda...
متن کاملConserved hydrogen bonding in tetrahydrocarbazolone derivatives: influence of solution-state assembly on crystal form nucleation.
Two tetrahydocarbazolone derivatives were found to show multiple unsolvated crystal forms. A persistent dimer motif was detected in solution by FTIR spectroscopy that is maintained in the kinetic crystal forms. Rationally introduced steric bulk induces the formation of a more stable catemeric form.
متن کاملHydrogen Bonding: Between Strengthening the Crystal Packing and Improving Solubility of Three Haloperidol Derivatives.
The purpose of this study is to confirm the impact of polar functional groups on inter and intra-molecular hydrogen bonding in haloperidol (HP) and droperidol (DP) and, hence, their effects on dissolution using a new approach. To confirm our theory, a new molecule: deshydroxy-haloperidol (DHP) was designed and its synthesis was requested from a contract laboratory. The molecule was then studied...
