Pyrazole-type complexes with Ni(II) and Cu(II)

Ni(ii) and Co(ii) complexes for the selective adsorption of anionic dyes from aqueous solutions

“…The bond lengths of the Ni-N bonds of complex 1 ranged from 2.113(3) to 2.122(3) Å, which were similar to the bond lengths range of the Ni-N bonds (1.958(2) to 2.143(2) Å) reported in the literature. [33][34][35][36][37] The central metal Ni(II) was connected by the Hptim ligand along the b-axis to form an infinite onedimensional chain structure (Fig. 1c).…”

Novel family of bis-pyrazole coordination complexes as potent antibacterial and antifungal agents

“…A large number of pyrazole based complexes have been synthesized over the last decades. 42,43 Our objective was to increase the number of coordination sites and exibility of such ligands by designing a new ligand made of a bis-pyrazole synthon, namely 1,5,5 0 -trimethyl-1H,1 0 H-3,3 0 -bipyrazole. The synthesis was undertaken following a simple reaction pathway.…”

Convenient Synthesis of Binary and Fused Pyrazole Ring Systems: Accredited by Molecular Modeling and Biological Evaluation

“…[2] Besides, this class of compounds is one of the most potent bioactive heterocyclic scaffolds revealing various notable biological activities such as antimicrobial, [3,4] antitubercular, [5] anticonvulsant, [6] antipyretic [7,8] and anti-angiogenic. [9] Also, a wide range of antagonistic activities of the metal complexes of pyrazole derivatives including antifungal activity, [7] potent antioxidant enzyme mimics, [10] anti-inflammatory and anticancer have been reported. [11] Recently, numerous based pyrazole derivatives are utilized in metal-organic frameworks (MOFs) as subunit for batteries applications, [12] He et al [13] reported great utility of pyrazols skeletons as green herbicides which are highly efficient and eco-friendly as showing high crop selectivity and low toxicity.…”
