Synthesis, crystal structure and desulfurization properties of zig-zag 1D coordination polymer of copper(II) containing 4-methoxybenzoic acid ligand

Synthesis, characterization and density functional theory of copper(II) complex and cobalt(II) coordination polymer for detection of nitroaromatic explosives

“…Detailed crystallographic data and structure refinement parameters are summarized in Table 1a, while selected bond lengths and bond angles are presented in Table 1b. 1 crystallizes in the The Cu1-O21 distances is 1.957( 9) Å (Table 1b) which compares favourably with the range 1.930-1.990 Å [22] usually observed for copper complexes. The bond length of the two Cu1-N11 bonds is 1.992(12) Å which agrees favourably with the reported range of 1.974-2.008 Å [23].…”

Removal of organic pollutant (pyrene) from aqueous solution using coordination polymer of [Cu(Pic)2(H2O)2]·H2O (CP-1) as adsorbent

“…Crystallographic data of the complex revealed the copper ion is polymerically almost in a conventional octahedral fashion with twofold picolinate ions bonded on side way of each of copper metal ions. The two equatorial carboxylate oxygen atoms bonded to copper that directly bond to the pyridine displayed a Cu-O bond length average of 1.947 Å, comparing favorably with the range 1.930-1.990 Å (Tella et al 2018) usually observed for copper complexes. The Cu-O bond length 2.697 Å observed in the other two axial oxygen atoms on copper metal is elongated in length representing the Jahn-Teller distortion effect (Jahn and Teller 1937).…”

Synthesis, structural and DFT investigation of Zn(nba)2(meim)2 for adsorptive removal of eosin yellow dye from aqueous solution

“…[45] For example, a copper(II) complex of 4-methoxybenzoic acid ligand with a surface area of 31.7 m 2 /g was found to have desulphurization capacity as a result of π-π stacking interaction between the sulphur-containing compound and the complex. [46] A negatively charged compound was reported to have a remarkable capability to adsorb the cationic dye methylene blue, as a result of electrostatic interaction. [47] A nickel coordination compound based on 5-(1H-benzoimidazol-2-ylsulfanylmethyl)-isophthalic acid (H 2 bismip) along with 4,4-bis(1-imidazolyl)bibenzene (bimb), was reported to show a remarkable adsorption capacity for methyl orange dye due to the formation of consecutive π-π stacking with bimb.…”
