In the title complex, [Ni(C₃₆H₂₆Cl₄N₄O₂)]·C₃H₆O, two 2,4-dichloro-benzoyl groups are grafted onto the methine groups of the Ni(II) complex Ni(tmtaa) (H₂tmtaa = 5,7,12,14-tetra-methyl-4,11-dihydro-dibenzo[b,i][1,4,8,11]tetra-aza-cyclo-tetra-decine). The complex has the shape of a saddle. The Ni atom is tetra-coordinated by the four N atoms of the macrocycle, forming a slightly tetra-hedrally dis...

In the title compound, [Ni(C12H6O4)(C21H18N4)(H2O)] n , the Ni(II) cation is coordinated by three carboxyl-ate O atoms of two naphthalene-1,4-di-carboxyl-ate anions, one water mol-ecule and two N atoms of two 1,1'-(9,9-dimethyl-9H-fluoren-2,7-di-yl)di-1H-imidazole (DFDI) ligands, giving rise to a slightly distorted octa-hedral geometry. The Ni(II) ions are linked by the DFDI ligands into chains...

In this study ternary Ni-P-CeO2 catalysts were first synthesized by the Co-electrodeposition method on a copper substrate and then characterized by means of microstructural and electrochemical techniques toward a hydrogen evolution reaction (HER). Also, for comparison other catalysts such as Ni-CeO2, Ni-P, and Ni were prepared and characterized by the same methods. The microstructure of the inv...

Some linear and nonlinear optical (NLO) properties of Ni(SCH)(4) and several of its derivatives have been computed by employing a series of basis sets and a hierarchy of methods (e.g., HF, DFT, coupled cluster, and multiconfigurational techniques). The electronic structure of Ni(SCH)(4) has been also analyzed by using CASSCF/CASPT2, ab initio valence bond, and DFT methods. In particular we disc...

In this paper, the authors present an experimental study of roughness characteristics of electroless Ni-B coatings and optimization of the coating process parameters based on L27 Taguchi orthogonal design. Three coating process parameters are considered viz. bath temperature, reducing agent concentration, and nickel source concentration. It is observed that concentration of reducing agent toget...

The asymmetric unit of the title helical coordination polymer, {[Ni(C(7)H(4)O(6)S)(C(10)H(8)N(2)S)(2)(H(2)O)(2)]·2H(2)O}(n), is comprised of an Ni(II) ion, one 5-sulfosalicylic acid dianion (HSSA), two 4,4'-dipyridylsulfide (4,4'-dps) ligands, and two coordinated and two uncoordinated water mol-ecules. The Ni(II) ion is coordinated by two water mol-ecules, one carboxyl-ate O atom of the HSSA di...

The Hai River Basin (HRB) is one of the most polluted river basins in China. The basin suffers from various types of pollutants including heavy metals and nutrients due to a high population density and rapid economic development in this area. We assessed the relationship between heavy metal accumulation by periphyton playing an important role in fluvial food webs and eutrophication in the HRB. ...
