The crystal structures of triethyl-1,3,5-triazine-2,4,6-tricarboxylate (I), triethyl-1,3,5-benzenetricarboxylate (II) and tris-2-hydroxyethyl isocyanurate (III) have been determined from conventional laboratory X-ray powder diffraction data using the differential evolution structure solution technique. The determination of these structures presented an unexpectedly wide variation in levels of d...

The aim of our research was to investigate theeffect of the length of the polymer chain and the concen-tration of triethyl citrate used as a plasticizer on the thermalstability of the film structure in the case of two ethyl cel-lulose films (EC 10 and EC 45) used for preparing MRdosage forms. The influence of storage time was studied bymonitoring the changes in the therm...

Stilbene derivatives are widely distributed in the nature and they possess various bioactivities that includes antimicrobial, antifungal, antioxidant, hepato protective, anti-HIV, cytotoxic, antiinflammatory and antiplatelet. We have synthesized novel derivatives of stilbenes by reacting various substituted phenyl acetic acid with aldehydes in presence of acetic anhydride and triethyl amine. Th...

In the title compound, C(6)H(16)N(+)·C(7)H(5)O(4) (-), the hy-droxy groups of the 3,4-dihy-droxy-benzoate anion form O-H⋯O hydrogen bonds to the carboxyl-ate groups of two adjacent anions, generating layers propagating in the ac plane. The triethyl-ammonium cations lie between these layers, forming N-H⋯O hydrogen bonds to the carboxyl-ate groups of the anions. The structure is consolidated by w...

The title compound, C(25)H(24)N(2)O(3) was prepared by the reaction of (Z)-2-(1H-indol-3-ylmethyl-ene)-1-aza-bicyclo-[2.2.2]octan-3-one with methyl p-(bromo-meth-yl)benzoate, under phase-transfer catalytic (PTC) conditions using triethyl-benzyl-ammonium chloride and 50% w/v aqueous NaOH solution in dichloro-methane. The crystal structure indicates the presence of a double bond with Z geometry c...
