Crystalline complexes of NH4+PF6– with trimethyl- and triethylbenzene-based tripodal compounds, bearing either pyrazole or indazole groups, were prepared and characterized by X-ray diffraction studies. The supramol. motifs observed in the crystal structures and the conformations of the tripodal mols. have been the subject of a detailed anal. and are described in this paper. The pyrazole-bearing side arms of the hosts with a trimethylbenzene scaffold are arranged in an aaa fashion and form a cavity including the ammonium ion. In the case of the triethylbenzene derivatives, the fully alternating arrangement of the pyrazole/indazole and Et groups is observed and by taking the Et groups into account, the conformation can be defined as ab’ab’ab’. The conformations observed in the crystals of the free host mols. can be defined as ab’ab’ba’ with the indazole-bearing arms arranged in an aab fashion. The crystal packings of the complexes are, among other things, characterized by the presence of NH···F and CH···F hydrogen bonds as well as by CBr···N and CBr···π halogen bonds in the case of the bromo-substituted derivatives This study involved multiple reactions and reactants, such as 1,1′,1”-((2,4,6-Trimethylbenzene-1,3,5-triyl)tris(methylene))tris(1H-pyrazole) (cas: 172606-26-7Recommanded Product: 172606-26-7).
1,1′,1”-((2,4,6-Trimethylbenzene-1,3,5-triyl)tris(methylene))tris(1H-pyrazole) (cas: 172606-26-7) belongs to pyrazole derivatives. The strategies for the synthesis of pyrazoles generally can be applied for the construction of indazoles. Pyrazole the presence of this nucleus in pharmacological agents of diverse therapeutic categories such as celecoxib, a potent anti-inflammatory, the antidepressant agent fezolamide have proved the pharmacological potential of the pyrazole moiety.
