ACETYLACETONATOSELENITO COMPLEXES OF COBALT(II) AND NICKEL(II)

Journal of Coordination Chemistry, 1987
Abstract Although mixed selenito complexes of Co(III) have been reported.1–4 there have been no previous reports of selenito complexes of metals in the 2+ oxidation state. In the present paper we describe the preparation of the first mixed selenito complexes of Co(II) and Ni(II).

Nickel(II) and cobalt(II) complexes of rhodanine

Transition Metal Chemistry, 1977
Nickel(II) and cobalt(II) complexes of rhodanine (Hrd) were prepared from the metal chloride or acetate and the ligand. With an excess of NH3, the octahedral [Ni(NH3)6](Rd)2 and [Co(NH3)5Rd]Rd complexes are ob-tained; use of only two NH3 equivalents per metal ion yields the Ni(Rd)2 sd HRd · NH3 and [Co(Rd)2 ] · 1.5 H2O complexes, the first with ...

Cymantrenecarboxylate complexes of nickel(II) and cobalt(II)

Russian Journal of Coordination Chemistry, 2011
Reactions of cymantrenecarboxylic acid (CO)3MnC5H4COOH (CymCOOH) with Ni(II) and Co(II) pivalates in boiling THF followed by extraction of the products with diethyl ether or benzene and treatment with triphenylphosphine gave the binuclear complexes LM(CymCOO)4ML (M = Ni (I) and Co (II); L = PPh3).

Cobalt(II) and nickel(II) complexes of carbamylmethylenephosphonates

Journal of Inorganic and Nuclear Chemistry, 1974
Abstract The coordinating ability of the organic compounds with the basic skeleton has been investigated and their completely chelated cobalt(II) and nickel(II) complexes have been isolated. These complexes have been characterized by means of their electronic and i.r.

THE MAGNETIC SUSCEPTIBILITY OF MOLTEN NICKEL(II) COMPLEXES

Journal of the American Chemical Society, 1957
Abstract The bis-( N -alkylsalicylaldimine) - nickel (II) complexes, which are diamagnetic in the solid state, become paramagnetic with moments ranging from 0.8 to 1.15 B.M. in the molten state.

1,5-Diarylbiguanides and their nickel( ii ) complexes

Dalton Trans., 2013
1,5-Diarylbiguanides, where the aryl groups are phenyl (HL1), 3,5-dimethylphenyl (HL2), 3,5-dimethoxyphenyl (HL3), 4-t-butylphenyl (HL4) or 4-bromophenyl (HL5), have been prepared and characterised. HL3 and HL5 have been structurally characterised by X-ray crystallography, which shows them to adopt the expected tautomeric form for biguanides. They have

Monomeric and Dimeric Disulfide Complexes of Nickel(II)

Inorganic Chemistry, 2010
Elemental sulfur reacts with a bulky bis(phosphine)nickel(0) complex to give a monomeric nickel(II) eta(2)-disulfido complex, oxidation of which results in the elimination of sulfur with dimerization to give an eta(2),eta(2)-disulfidodinickel(II) derivative in which the S-S bond can be reductively cleaved in a redox-reversible fashion.

Oxygen Reactivity of a Nickel(II)−Polyoximate Complex

Inorganic Chemistry, 2002
The ligand tris(2-hydroxyiminopropyl)amine (Ox(3)H(3)) binds to nickel(II) in multiple protonation states. In the neutral state, the X-ray crystal structure of the monomeric complex [Ni(Ox(3)H(3))(NO(3))(H(2)O)](NO(3)).(H(2)O), 1, has six-coordinate pseudo-octahedral geometry, with binding of the amine and three oxime nitrogens, a nitrate, and a water.

Two furopyridine complexes of nickel(II) isothiocyanate

Acta Crystallographica Section C Crystal Structure Communications, 2004
Pyridine fused with a furan ring (fupy), and its dimethyl derivative, have been used for the first time as ligands to synthesize potentially new Werner clathrates. The extended aromatic system of pyridine-like ligands influences considerably the molecular structure of prepared nickel complexes.
