X-ray analysis

1,2,4-Triazolyl-3,5-diacetic acid ethyl ester was synthesized by condensation of hydrazine hydrate and N-acyl ethyl 3-ethoxy-3-iminopropanoate. Other methods for the synthesis are considered and their comparative analysis is carried out. The molecular structure of the title compound was established by X-ray analysis. Hirshfeld surface analysis was performed to investigate intermolecular interactions.

Arylamides of hetaryl-2-thiocarbonic acid were synthesized via Willgerodt–Kindler modified reaction. The final products were studied by means of chemical analysis, IR- and 1H NMR-spectroscopy. The coordination compounds of the general formula [Cu(HL4)Cl2]2] • хCH3OH (х = 0, 2) were obtained via traditional and direct synthesis based on benzimidazol-2-N-(4-ethoxyphenyl)carbothiamide (HL4). Using X-ray analysis the molecular and crystal structures of [Cu(HL4)Cl2]2] • 2CH3OH complex were determined.
