I found the field of Chemistry very interesting. Saw the article Syntheses, characterization and DFT studies of two new homo-dinuclear zinc(II) complexes based on pyrazole and 3,5-dimethylpyrazole ligands published in 2020.0. COA of Formula: C5H8N2, Reprint Addresses Ngoune, J (corresponding author), Univ Dschang, Dept Chem, Dschang, Cameroon.. The CAS is 67-51-6. Through research, I have a further understanding and discovery of 3,5-Dimethyl-1H-pyrazole

Two new homo-dinuclear zinc(II) complexes, bis(mu-pyrazolato-) bis[(formato)(pyrazole)zinc(II)], [{Zn(OCHO)(pzH)}(2)(mu-N2H3C3)(2)] (1) and bis(mu-3,5-dimethylpyrazolato)bis[(formato)(-3,5-dimethylpyrazole) zinc(II)], [{Zn(dmpzH)(OCHO)}(2)(m-N2H7C5)(2)] (2), were synthesized through the reactions of zinc(II) formate dihydrate, Zn(OCHO)(2)center dot 2H(2)O with pyrazole (pzH = C3H4N2) and 3,5-dimethyl-pyrazole (dmpzH = C5H8N2), respectively, in toluene at room temperature. These dinuclear complexes have been characterized using different analytical techniques; elemental and thermogravimetric analyses, IR and H-1-NMR spectroscopies, single-crystal X-ray diffraction and DFT studies. Compound 1 crystallized in the P (1) over bar space group of the triclinic crystal system with unit cell parameters a = 8.205(3) angstrom, b = 8.864(5) angstrom, c = 14.486(7) angstrom, alpha = 104.929(14)degrees, beta = 91.214(11)degrees and gamma = 106.921(8)degrees. Compound 2 crystallized in the P2(1)/c space group of the monoclinic crystal system with cell parameters a = 8.400(3) angstrom, b = 11.020(4) angstrom, c = 14.930(5) angstrom, alpha = gamma = 90 degrees and beta = 106.3(10)degrees. Pseudo-tetrahedral coordination geometries were observed around the zinc(II) centers in both complexes, constructed by one oxygen atom from a formate anion and three nitrogen atoms from one pzH and two pyrazolato in 1 or one dmpzH and two 3,5-dimethylpyrazolato in 2. The bulk of these materials are consolidated by weak and strong N-H center dot center dot center dot O, C-H center dot center dot center dot O, C-N center dot center dot center dot O and C-H center dot center dot center dot pi, N-H center dot center dot center dot pi and C-O center dot center dot center dot O intra/intermolecular interactions resulting to zigzag networks containing empty voids. DFT studies on both compounds revealed their optimized structures, frontier molecular orbitals, theoretical IR frequencies and the global reactivity descriptors. [GRAPHICS]
