Basicity of water in dipolar aprotic solvents using the 1,4,8,11-tetramethyl-1,4,8,11-tetra-azacyclotetradecane nickel(II) cation as a probe of electron-pair acceptance
TL;DR: In this article, the basicity of water in 1,2-dichloroethane (1,2DCE), NB, NM, N,N-dimethylacetamide (DMA), and 1, 2-DCE-DMA mixtures has been examined using spectral data of 1,4,8,11-tetramethyl-1, 4, 8, 11 -tetra-azacyclotetradecane nickel(II){[Ni(TMC)]2+}.
Journal ArticleDOI
Effect of Lattice Anions on the Ligand Substitution Reaction of Tris(1,10-phenanthroline)metal(II) Complexes: [M(phen)3]SO4 and [M(phen)3]X2 (M: Fe(II), Co(II), Ni(II); X: Cl−, Br−, I−)
TL;DR: In this paper, an exothermic peak appeared in the differential scanning calorimeter (DSC) curve which correlates with a ligand substitution in which anionatobis(1,10-phenanthroline) metal(II) complexes are formed.
Journal ArticleDOI
Axial co-ordination and ion-pair formation for R,S,R,S-1,4,8,11-tetramethyl-1,4,8,11-tetra-azacyclotetradecanenickel(II) perchlorate in various mixed solvents with nitrobenzene

Basicity of water in organic solvents (nitromethane, propane-1,2-diyl carbonate and acetone) using the 1,4,8,11-tetramethyl-1,4,8,11-tetra-azacyclotetradecanenickel(II) cation as a probe of electron-pair acceptance
TL;DR: In this paper, the basicity of water in nitromethane (NM), propane-1,2-diyl carbonate (PDC) and acetone (AC) was examined using spectral data for (1R,4S,8R,11S)-1,4,8,11-tetramethyl-1.4, 8, 11tetra-azacyclotetradecane-nickel(II){[Ni(TMC)]2+}.
Journal ArticleDOI
Basicity of Water in Hydrogen-Bonded Networks of Methanol–1,2-Dichloroethane Mixtures Using the [(1R,4S,8R,11S)-1,4,8,11-Tetramethyl-1,4,8,11-tetraazacyclotetradecane]nickel(II) Cation as a Probe of Electron-Pair Acceptance
TL;DR: In this article, the basicity of water in methanol (MeOH) and MeOH-1,2-dichloroethane (DCE) mixtures was examined by using spectral data of the title square planar chelate cation ([Ni(tmc)]2+).
