I found the field of Crystallography very interesting. Saw the article Crystal structure of bis{(3,5-dimethylpyrazol-1-yl)dihydro[3-(pyridin-2-yl)pyrazol-1-yl]borato}iron(II) published in 2020.0. Application In Synthesis of 3,5-Dimethyl-1H-pyrazole, Reprint Addresses Ossinger, S (corresponding author), Christian Albrechts Univ Kiel, Inst Anorgan Chem, Max Eyth Str 2, D-24118 Kiel, Germany.. The CAS is 67-51-6. Through research, I have a further understanding and discovery of 3,5-Dimethyl-1H-pyrazole
The structure determination of [Fe(C13H15BN5)(2)] was undertaken as part of a project on the modification of the recently published spin-crossover (SCO) complex [Fe{H2B(pz)(pypz)}(2)] (pz = pyrazole, pypz = pyridylpyrazole). To this end, a new ligand was synthesized in which two additional methyl groups are present. Its reaction with iron trifluoromethanesulfonate led to a pure sample of the title compound, as proven by X-ray powder diffraction. The asymmetric unit consists of one complex molecule in a general position. The Fe-II atom is coordinated by two tridentate N-binding {H2B(3,5-(CH3)(2)-pz)(pypz)}(-) ligands. The Fe-N bond lengths range between 2.1222 (13) and 2.3255 (15) angstrom, compatible with Fe-II in the high-spin state, which was also confirmed by magnetic measurements. Other than a very weak C-H center dot center dot center dot N non-classical hydrogen bond linking individual molecules into rows extending parallel to [010], there are no remarkable intermolecular interactions.
