Bis{2-[3-(hy­droxy­imino-κN)butan-2-yl­idene]-N-methyl­hydrazinecarbothio­amide-κ²N²,S}nickel(II) dichloride

The asymmetric unit of the title compound, [Ni(C₆H₁₂N₄OS)₂]Cl₂, contains two independent Ni^II complex cations and four chloride anions. Each Ni^II ion is six-coordinated in a distorted octa­hedral geometry by four N atoms from the two imine and two oxime groups and two S atoms from the thione group. In the crystal, the cations and anions are linked through N—H...Cl and O—H...Cl hydrogen bonds into infinite chains propagating along [10]. Weak inter­molecular C—H...O and C—H...Cl hydrogen bonds are also observed.

In the title complex, [Ni(C₇H₁₄N₄OS)₂]Cl₂, the Ni^II ion is six-coordinated in a distorted octa­hedral geometry by four N atoms from the two imine and two oxime groups, and two S atoms from the thione groups. Two chloride ions complete the asymmetric unit. In the crystal, mol­ecules are linked through N—H...Cl and O—H...Cl hydrogen bonds into an infinite chain propagating along [101].

(E)-2-[(E)-3-(Hy­droxy­imino)­butan-2-yl­idene]-N-methyl­hydrazinecarbothio­amide

In the title compound, C₆H₁₂N₄OS, an intra­molecular N—H...N hydrogen-bond is present giving rise to an S(5) ring motif. In the crystal, double-stranded chains propagating along [10] are formed via pairs of O—H...S and N—H...S hydrogen bonds. The chains are further stabilized by C—H...S interactions.
