Crystal structure and Hirshfeld surface analysis of (succinato-κO)[N,N,N′,N′-tetra­kis­(2-hy­droxy­eth­yl)ethyl­enedi­amine-κ(5) O,N,N′,O′,O′′]nickel(II) tetra­hydrate

In the title compound, [Ni(C(10)H(24)N(2)O(4))(C(4)H(4)O(4))]·4H(2)O, the Ni(II) 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.
