Abstract top

In the title compound, [Ni(C17H14N3S2)2]·2C3H7NO, the Ni atom (site symmetry \overline{1}) is N,S-chelated by two deprotonated Schiff base anions in a distorted square-planar geometry. The dihedral angle between the aromatic ring planes within the ligand is 86.37 (13)°. In the crystal structure, an N-H...O hydrogen bond links the complex to the dimethyl­formamide solvent mol­ecule.

Experimental top

Benzyl (1H-indol-2-ylmethylene)hydrazinecarbodithioate ethanol hemisolvate (2 mmol, 0.65 g) was dissolved in ethanol (30 ml) along with several drops of triethylamine. To the resulting clear solution was added an ethanol solution (10 ml) containing 1 mmol (0.25 g) of nickel acetate tetrahydrate. The mixture was heated for an hour. The product that separated was recrystallized from DMF to yield brown blocks of (I).

Refinement top

Hydrogen atoms were placed at calculated positions (C–H = 0.95–0.99Å, N–H = 0.88Å) and refined as riding with U(H) = 1.2–1.5 times Ueq(C,N).
