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

Abstract

In the title complex, [Ni(C6H6N3OS)2]·2CH3OH, the NiII 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 NiII 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 N atom that is not bonded to the NiII 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%).
