Synthesis and structural characterization of 5-coordinate cobalt(II), copper(II) and 4-coordinate zinc(II) complexes containing N′-cyclopentyl substituted N,N-bispyrazolylmethylamine

Dimeric metallacycles and coordination polymers: Zn(II), Cd(II) and Hg(II) complexes of two positional isomers of a flexible N,O-hybrid bispyrazole derived ligand

“…Selected bond lengths and angles are shown on Table 3. All values agree with similar compounds reported in the literature [33,34,50,51]. In this polymer, adjacent Zn(II) atoms are connected by L2 via a NN'-bridged mode in an anti conformation, resulting in an infinite helical-chain along the c axis.…”

Synthesis, Characterization, DFT, and Thermogravimetric Analysis of Neutral Co(II)/Pyrazole Complex, Catalytic Activity toward Catecholase and Phenoxazinone Oxidation

“…The V max value was found to be 0.631 µmol•L −1 •min −1 and K m = 0.007 mol•L −1 . These kinetic parameters values are compatible with the results of others using similar complexes [3][4][5][6][7][8][9][10][11]. In addition, by comparing this with results from the literature, one can classify the desired Co(II)/pyrazole complex as working well in the catecholase process in the absence of an oxidizing agent besides atmospheric oxygen.…”

“…N-pyrazole derivative ligands and their complexes are used because of their stability, catalytic coordination abilities and versatility [1,2]. In particular, Co(II)/pyrazole complexes have received attention in several applications, where most researchers are using these complexes as catalysts, with an eye on their promising medical role [3][4][5][6][7].…”
