Two new Ni(II) complexes involving the ancillary ligand bis[(pyridin-2-yl)methyl]amine (bpma) and two different carboxylate ligands, i.e. homophthalate [hph; systematic name: 2-(2-carboxylatophenyl)acetate] and benzene-1,2,4,5-tetracarboxylate (btc), namely catena-poly[[aqua{bis[(pyridin-2-yl)methyl]amine-κ(3)N,N',N''}nickel(II)]-μ-2-(2-carboxylatophenyl)aceteto-κ(2)O:O'], [Ni(C9H6O4)(C12H13N3)...

the reaction of an equivalent of 2- mercaptoethyl ammonium chloride with an equivalent of 2,6-diformyl -4- methyl phenol produced monoamine which was reacted with half equivalent of 1,2-diamine ethane to produce ethylene-bis-6-(2-mercapto-ethyl-imine)-methyl -4- methyl phenol [h4l]. the ligand was reacted with metal ions[cr(iii), mn(ii), fe(ii), co(ii), ni(ii), cu(ii), zn(ii), cd(ii), and hg(ii...

The structure of the title compound, [Ni(C(6)H(16)N(2))(2)]Br(2) or [Ni(Et(2)en)(2)]Br(2) (Et(2)en is asymmetric N,N-diethyl-ethylene-diamine), containing an Ni(II) atom (site symmetry ) in square-planar NiN(4) coordination, is described and contrasted with related structures containing Ni(II) in octa-hedral coordination with axial X(-) ligands (X(-) = variable anions). The dialkyl-ated N atom ...

The monomeric title nickel(II) complex of a salicylaldimine, [Ni(C(20)H(14)N(2)O(4))]·2CH(3)OH, was obtained by the reaction of 2,4-dihydroxy-benzaldehyde and 1,2-phenyl-enediamine with nickel(II) acetate. The Ni(II) atom is coordinated by two N atoms [Ni-N = 1.839 (2) Å] and two O atoms [Ni-O = 1.8253 (19) Å] in an approximately square-planar geometry. In the crystal structure, inter-molecular...

This researchdescribe wastewater pre-treatment that contaminated with Methylene Blue dye (MB) and Ni(II) ion by Athelia Bombacina fungus dead biomass (ABFDB). Researches finding on ABFDB characterization by SEM, XRD, CHNS and FT-IR analysis show that ABFDB can be used as efficient sorbent, because ABFDB cellular wall consist of Chit...

The asymmetric unit of title complex, [Ni(C(20)H(13)BrN(2)O(2))(C(5)H(5)N)], contains two independent mol-ecules. In each mol-ecule, the central Ni(II) atom has a square-planar environment, formed by the tridentate hydrazone and the monodentate pyridine ligands, with the N atoms in a trans arrangement about the Ni(II) atom.

Reaction of the mononuclear Ni(II) complex [Ni{2-Py(6-NH2)NHC(S)NP(S)(OiPr)2}2] with different salicylaldehydes leads to new antiferromagnetically coupled trinuclear double-stranded helicates , where Ni(II) metal ions are coordinated by two bis-anionic thiourea ligands and two deprotonated molecules of the corresponding aldehyde.

We report the synthesis and magnetic characterisation of a series of planar [M₇] (M= Ni(II), Zn(II)) disc complexes [Ni₇(OH)₆(L₁)₆](NO₃)₂ (1), [Ni₇(OH)₆(L₁)₆](NO₃)₂·2MeOH (2), [Ni₇(OH)₆(L₁)₆](NO₃)₂·3MeNO₂ (3), [Ni₇(OH)₆(L₂)₆](NO₃)₂·2MeCN (4), [Zn₇(OH)₆(L₁)₆](NO₃)₂·2MeOH·H₂O (5) and [Zn₇(OH)₆(L₁)₆](NO₃)₂·3MeNO₂ (6) (where HL₁ = 2-iminomethyl-6-methoxy-phenol, HL₂ = 2-iminomethyl-4-bromo-6-methox...

the present study was carried out to investigate three different adsorbents; dry cells of thebacterium exiguobacterium sp. 27, polyaniline and a mixture of both in different ratios for removal of ni(ii)from aqueous solution. the results showed that the adsorption of ni(ii) using dry cells of exiguobacteriumsp. 27 was very fast and the equilibrium time was 15 min, while the equilibrium time for ...
