“…These interactions presumably prevented the approach of C 60 .− species to form dimers. The geometry of the CV + cations in salt 1 was similar to those reported previously for CV + in (CV + )(BPh 4 − ) and (CV + )[Ni(dmit) 2 − ] ⋅ C 6 H 6 (dmit=1,3‐dithiol‐2‐thione‐4,5‐dithiolate) …”

The reduction of fullerene C60 by zinc dust in the presence of crystal violet cations (CV(+) ) yielded a deep-blue solution, from which crystals of (CV(+) )(C60 (.-) )⋅0.5 C6 H4 Cl2 (1) were obtained by slow mixing with n-hexane. The salt contained isolated, closely packed zigzagged chains that were composed of C60 (.-) radical anions with a uniform interfullerene center-to-center distance of 9.98 Å. In spite of the close proximity of the fullerenes, they did not dimerize, owing to spatial separation by the phenyl substituents of CV(+) . The room-temperature conductivity of compound 1 was 3×10(-2) S cm(-1) along the fullerene chains. The salt exhibited semiconducting behavior, with an activation energy of Ea =167 meV. Spins localized on C60 (.-) were antiferromagnetically coupled within the fullerene chains, with a Weiss temperature of -19 K without long-range magnetic ordering down to 1.9 K.

“…Additionally, it is referred to as basic violet or rosaniline chloride [ 6 ]. It is a member of a triphenylmethane dye class with the chemical formula C 20 H 20 ClN 3 [ 7 ] and boasts an impressive planar conjugated π structure ( Figure 1 ) [ 8 ]. Despite this, the basic fuchsine (BF) dye is combustible, anesthetic, and bacteriostatic [ 9 , 10 ].…”

Highly Selective Removal of Cationic Dyes from Wastewater by MgO Nanorods

et al. 2022

The organic synthetic dyes employed in industries are carcinogenic and harmful. Dyes must be removed from wastewater to limit or eliminate their presence before dumping into the natural environment. The current study aims to investigate the use of MgO nanoparticles to eliminate basic fuchsine (BF), as a model cationic dye pollutant, from wastewater. The MgO nanorods were synthesized through a coprecipitation method. The obtained nanocomposite was characterized using various techniques such as X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), Brunauer–Emmett–Teller (BET), and FTIR spectroscopy. It was found that the variation of dye concentration and pH influenced the removal of BF by MgO. The adsorption capacity of 493.90 mg/g is achieved under optimum operating conditions (pH = 11, contact time = 236 min, and initial BF concentration = 200 ppm). Pseudo-second-order adsorption kinetics and Freundlich isotherm models best fitted BF sorption onto MgO nanorods. The BF sorption mechanism is associated with the electrostatic attractions and hydrogen bond between the O–H group of MgO and the NH2 groups of BF, as indicated by the pH, isotherms, and FTIR studies. The reusability study indicates that MgO was effectively used to eliminate BF in at least four continuous cycles. The investigation of MgO with different dyes suggests the high adsorption selectivity of BF, crystal violet (CV), and malachite green (MG) dyes compared with methyl orange (MO) dye. Overall, MgO nanorods can act as a potential and promising adsorbent for the efficient and rapid removal of cationic dyes (CV, MG, and BF) from wastewater.

“…Therefore, a considerable number of studies have been conducted on the correlation between the molecular arrangement and the physical properties. [32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51] The reports by K. Dai and his coworkers suggested the importance of the alkyl chain length introduced in the counter cation on the crystal structure of [Ni(dmit) 2 ] complex salts. 46 They also reported that the crystal structure of alkylated salts depend on the correlation between the length of the cation and anion, namely the CLCA principle.…”

Five types of odd–even effect and crystal structure changes brought about by ω-phenylalkyl group in [Ni(dmit)₂] complex salts

A series of [Ni(dmit)2] (dmit: 1,3-dithiole-2-thione-4,5-dithiolate) salts of ω-phenylalkyl-trimethylammonium (CnPh: n is the alkylene chain length; n = 2-5) have been prepared and characterized by X-ray crystallographic structural analysis. All complex salts are found to be composed of an alternating stack of [Ni(dmit)2] anions and CnPh cations, whereas the crystal structures are different in each complex. Interestingly, this series exhibited five types of odd-even effects in the crystal structures: 1. [Ni(dmit)2] anion length, 2. CnPh cation length, 3. orientation of the alkylene group against the terminal phenyl group, 4. relative orientation of the terminal phenyl group against [Ni(dmit)2] anions, 5. structure of dimerized [Ni(dmit)2] anions. The last odd-even effect led to an unusual vertical dimer structure. The vertical dimer is a unique structure in [M(dmit)2] complex salts (M = transition metal) and has not been reported. The introduction of a terminal phenyl group is concluded to have increased the steric effect and led to a marked structural difference between odd and even-numbered complex salts, i.e. the odd-even effect.
