X-Ray characterization of 3-methyl-6,8-di(2-pyridyl)-[1,2,3]triazolo[5′,1′:6,1]pyrido[2,3-d]pyrimidine

2005

The structure of a new compound 3-methyl-6,8-di(2-pyridyl)[1,2,3]triazolo[5′,1′:6,1]pyrido[2,3- d]pyrimidine 3, formed in the reaction of 3-methyl-[1,2,3]triazolo[1,5-a]pyridine with 2-cyanopyridine, is determined by X-ray diffraction analysis.

Synthesis of a Novel Hydrazone of Thieno[2,3-d]pyrimidine Clubbed with Ninhydrin: X-ray Crystal Structure and Computational Investigations

2023

The novel hydrazone-containing thieno[2,3-d]pyrimidine, namely, N′-(1,3-dioxo-1,3-dihydro-2H-inden-2-ylidene)-2-(4-oxo-5,6,7,8-tetrahydrobenzo[4,5]thieno[2,3-d]pyrimidin-3(4H)-yl)acetohydrazide 4 was synthesized in a very good yield from the reaction of the triketoester 1 or ninhydrin 2 with the exocyclic acetohydrazide 3 in methanol. Good-quality crystals of 4 were obtained by recrystallization of the compound from the DMF/MeOH solvent mixture. The target product 4 crystallized in the triclinic crystal system and P-1 space group. The topology analysis of molecular packing indicated that the H…H (30.4%), O…H (22.0%) and H…C (17.0%) contacts are the most dominant i…
