Crystal structure and Hirshfeld surface analysis of bis{(Z)-N'-[(E)-(furan-2-yl)methylidene]carbamo-hydrazonothioato}nickel(II) methanol disolvate.

In the title complex, [Ni(C₆H₆N₃OS)₂]⋅2CH₃OH, the Ni^II atom is coordinated by the S and N atoms of two N'[(Z)-(furan-2-yl)methylidene]carbamohydrazonothioic acid ligands in a distorted square-planar geometry. The two mutual ligands bound to Ni^II are also connected by C--H⋯S interactions, while the H atoms of the NH₂ group of the ligands form R₄⁴(8) motifs with the O atoms of the solvent ethyl alcohol molecules. At the same time, the OH groups of the solvent ethyl alcohol molecules form parallel layers to the (011) plane by the O--H⋯N interactions with the ligand Ni^II atom that is not bonded to the Nin atom.. The layers are connected by van der Waals interactions. A Hirshfeld surface analysis indicates that the most important contacts are H⋯H (37.7%), C⋯H/H⋯C (14.6%), O⋯H/H⋯O (11.5%) and S⋯H/H⋯S (10.6%).
