The hydrothermal synthesis and X-ray crystal structure of Ag (1)-4, 4"-bipyridine-based coordination polymer
Hydrothermal synthetic were studied for the preparation of coordination polymeric material basedon Ag (I) and 4, 4"-bipy. A polymeric compound [Ag (4, 4'-bipy)].NO3. (I), was prepared andstructurally characterized by single crystal X-ray diffraction. Compound 1(91% yield) was isolatedfrom the reaction of AgNO3 with 4, 41bipy in 2:1 molar ratio. In compound I. each silver (I) islinked to two nit...
متن کامل6-Fluoro-4-oxochroman-2-carboxylic acid
The title compound, C(10)H(7)FO(4), is an inter-mediate in the synthesis of the drug Fidarestat, (2S,4S)-2-aminoformyl-6-fluoro-spiro[chroman-4,4'-imidazolidine]-2',5'-dione. The di-hydro-pyran-one ring adopts an envelope conformation with the asymmetric C atom in the flap position. In the crystal, the mol-ecules are linked into zigzag chains along [100] by O-H⋯O hydrogen bonds and C-H⋯π inter-...
متن کامل4′-Hydroxybiphenyl-4-carboxylic acid
The title compound, C(13)H(10)O(3), has potential oxygen donor and acceptor sites. Inter-molecular hydrogen bonding between neighboring carboxyl-ate groups leads to the formation of hydrogen-bonded dimers [graph-set motif R(2) (2)(8)]. A second hydrogen-bonding inter-action between the hydr-oxy groups generates a chain and extends the structure into a lamellar layer. One of the benzene rings is...

significance as calcium-channel modulators in the treatment of cardiovascular diseases, such as hypertension, cardiac arrythmias or angina.1 In recent years, interest has also been focused on aza-analogs of dihydropyridines, such as dihydropyrimidines, which show a very similar pharmacological profile to that of dihydropyridine calcium channel modulators.2 In a continuation of these studies, ri...
متن کاملCrystal structure of 4-aminobenzoic acid–4-methylpyridine (1/1)
In the title 1:1 adduct, C6H7N·C7H7NO2, the carb-oxy-lic acid group is twisted at an angle of 4.32 (18)° with respect to the attached benzene ring. In the crystal, the carb-oxy-lic acid group is linked to the pyridine ring by an O-H⋯N hydrogen bond, forming a dimer. The dimers are linked by N-H⋯O hydrogen bonds, generating (010) sheets.
