The ligand bis(2-benzimidazolyl)propane coordinates to Ni II with a zero-field splitting parameter D (-14.3 cm -1 ) and a ferromagnetic exchange between the Ni ions in the dinuclear with chloride as an anion, thereby forming a dinuclear compound with the formula: [NiCl 2 (tbz) 2 ] 2 (C 2 H 6 O) 2 .
The six-step synthesis of a chiral, pentadentate dihydrosalen ligand, carrying a mercaptomethyl group as additional binding site, is described. When this ligand was treated with nickel(I1) salts, a planar tetracoordinated nickel chelate was obtained, and not the expected pentacoordinated species. Th
## Abstract NiCl~2~Β·6H~2~O and 2,2β²βbipyridine (bipy) (1:1) were allowed to react under ambient conditions in dimethyl sulfoxide in the presence of acetylacetone (Hacac). The resulting green solution was concentrated in vacuo, and a green solid was isolated by precipitation with cold acetone. Xβray
