We have recently synthesized [Ni (MAP) ] complex [H-MAP= 2- (methylamino) pyridine]. 2- (Methy1amino)pyridine reacts with MeLi in THF and generates the lithium salt (Li-MAP). Further reaction of NiCl with two equivalent of this ligand in THF leads to the formation of a dark red solution. Analytical data, molecular weight, and magnetic susceptibility of this complex confirm the formula [N...

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...

Complex engineered nanomaterials (CENs) are a rapidly developing class of structurally and compositionally complex materials that are expected to dominate the next generation of functional nanomaterials. The development of methods enabling rapid assessment of the toxicity risk associated with this type of nanomaterial is therefore critically important. We evaluated the toxicity of three differe...

The reaction of 2 equivalents of 2-methyl-1,4-bis(2,6-dimethylphenyl)-1,4-diaza-1,3-butadiene, ((1)L(Ox))(0), or 2-methyl-1,4-bis(2,6-diisopropylphenyl)-1,4-diaza-1,3-butadiene, ((2)L(Ox))(0), in diethyl ether or n-hexane with 1 equivalent of Ni(cdt) where (cdt)(0) is the ligand cyclododecatriene affords dark red, diamagnetic precipitates of [Ni(II)((1)L )(2)] () and of [Ni(II)((2)L )(2)] (). T...

Two silylene nickel carbonyl complexes of composition L·Ni(CO)(3) (1) {L = PhC(NtBu)(2)SiCl} and L'(2)·Ni(CO)(2) (2) { L' = RSiCl(2), R = (1,3-bis-(2,6-diisopropylphenyl)imidazol-2-ylidene)} were prepared by reacting 1 equivalent of Ni(CO)(4) with 1 equivalent of heteroleptic chlorosilylene L for 1 and with 2 equivalents of carbene stabilized dichlorosilylene L' for 2 in toluene at room tempera...

The title compound, [Ni(C(17)H(11)ClN)Cl(C(3)H(9)P)(2)], was obtained as a product of the reaction of [Ni(PMe(3))(4)] with a molar equivalent of 2,6-dichloro-N-naphthyl-benzaldehyde-amine in diethyl ether. The τ parameter is 0.3, indicating that the coordination geometry is square-pyramidal. The Ni(II) atom lies in the center of a square pyramidal in which one C, one Cl and two P atoms form the...
