In the tetranuclear copper(II) complex Cu<sub>4<\/sub>OCl<sub>6<\/sub>L<sub>4<\/sub> where L = 3,5-dimethylpyrazole, four copper atoms [separated by 3.070(2) &#8211; 3.198(3) \u00c5] encapsulate central oxygen atom in a distorted tetrahedral arrangement, with the Cu-O bond lengths of 1.903(6) &#8211; 1.914(6) \u00c5, and the Cu-O-Cu angles of 107.3(3) &#8211; 114.3(3)\u00b0. Between each pair of copper atoms, there is a bridging chlorine atom with Cu-Cl1 distances of 2.340(4) &#8211; 2.509(3) \u00c5. Closer inspection of the Cu-Cl distances reveals grouping of values around every copper atom in two &#8216;short&#8217; and one &#8216;long&#8217; distances. Average values are 2.375 \u00c5 and 2.459 \u00c5 for eight short and six long Cu-Cl distances, resp. Copper coordination sphere is completed by the 3,5-dimethylpyrazole ligand with Cu-N distances of 1.952(7) &#8211; 1.957(9) \u00c5. Coordination polyhedron can be described as a slightly distorted trigonal bipyramid where three chlorine atoms lie in the equatorial positions while the central oxygen and the pyridine nitrogen from pyrazolyl ligand are placed at the axial sites. The structure in general is analogous to the structures of previously described tetranuclear complexes of copper [Cu<sub>4<\/sub>(O)(u-X)<sub>6<\/sub>L<sub>4<\/sub>], where L = ligand containing N, O or P donor and X is halogen. Direct contact between the tetranuclear units is achieved by the N-H&#8230; Cl hydrogen bonds. In the experiment, the researchers used many compounds, for example, 3,5-Dimethyl-1H-pyrazole-1-carboxamide (cas: 934-48-5<a href=\"https:\/\/www.ambeed.com\/products\/934-48-5.html\">COA of Formula: C6H9N3O<\/a>).<\/p>\n<p>3,5-Dimethyl-1H-pyrazole-1-carboxamide (cas: 934-48-5) belongs to pyrazole derivatives. Pyrazoles, a five-membered heterocycle containing two adjacent nitrogen atoms, are the core structures found in a number of molecules that possess a wide range of pharmaceutical and agricultural activities. The presence of both electronegative nitrogen atoms in the pyrazole ring reduces the electron density of the C3- and C5-positions leaving electron density of C4-position unaltered. Thus the C4-position is vulnerable to electrophilic attack. The C3 electrophilic-position may undergo deprotonation in the presence of a strong base leading to ring opening.<a href=\"https:\/\/www.ambeed.com\/products\/934-48-5.html\">COA of Formula: C6H9N3O<\/a><\/p>\n<p>Referemce:<br \/><a href=\"https:\/\/en.wikipedia.org\/wiki\/Pyrazole\">Pyrazole &#8211; Wikipedia<\/a>,<br \/><a href=\"https:\/\/www.sciencedirect.com\/topics\/chemistry\/pyrazoles\">Pyrazoles &#8211; an overview | ScienceDirect Topics<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>3,5-Dimethyl-1H-pyrazole-1-carboxamide (cas: 934-48-5) belongs to pyrazole derivatives.
