Crystal structure and Hirshfeld surface analysis of (succinato-κO)[N,N,N′,N′-tetrakis(2-hydroxyethyl)ethylenediamine-κ5O,N,N′,O′,O′′]nickel(II) tetrahydrate

Abstract

In the title compound, [Ni(C10H24N2O4)(C4H4O4)]·4H2O, the NiII cation is octahedrally coordinated by one O atom of the succinate anion and three O atoms and two N atoms from an N,N,N′,N′-tetrakis(2-hydroxyethyl)ethylenediamine molecule. In the crystal, molecules are linked by O—H...O and C—H...O hydrogen bonds, forming a three-dimensional supramolecular architecture. Hirshfeld surface analyses and two-dimensional fingerprint plots were used to analyse the intermolecular interactions present in the crystal, indicating that the most important contributions for the crystal packing are from H...H (63.3%) and H...O/O...H (34.5%) interactions.
