{N,N′-Bis[1-(2-pyridyl)ethylidene]propane-1,2-diamine}bis(thiocyanato-κN)nickel(II)

“…The Ni atom is coordinated by four N atoms of a Schiff base ligand and two N atoms from two thiocyanate ligands, forming an octahedral geometry. The bond lengths (Table 1) related to the central Ni atom are comparable to those observed in other nickel(II) complexes with Schiff bases (Liu et al, 2006;Li & Wang, 2007;Liu et al, 2007;Ali et al, 2006;Knight et al, 2007).…”

Bis{2-[(2-hydroxy-2-methylpropyl)iminomethyl]-4-nitrophenolato}nickel(II) dimethylformamide monosolvate

“…In the title complex two uninegative tridentate ligands, 5-nitro salicylaldehydene-2,2-dimethyl ethylimine-1-ol, coordinate to the nickel atom producing N 2 O 4 in a slightly distorted octahedral coordination environment. The distortion can be justified by the bond angles formed by the coordinating atoms to the metal: 2Å] as is usually found in such complexes (Ali et al 2006;Butcher et al 1981Butcher et al , 2009Gultneh et al 1998;Mustafaa et al 2009;Zhang et al 2010).…”

Bis[1,3-dihydroxy-2-hydroxymethyl-2-(2-oxidobenzylideneamino)propane-κ3N,O,O′]nickel(II) pyridine solvate

“…The preceeding paper reports the crystal structure of the Ni complex based on the ligand derived by condensing 5-nitrosalicyaldehyde with tris(hydroxymethylamino)methane; the compound crystallizes as a pyridine solvate (Ali et al, 2006). The title nickel analog, (I) (Fig.…”
