[N-(2-Hydroxy-ethyl)ethyl-enediamine]oxalatocopper(II).

ABSTRACT: In the title mononuclear copper(II) compound, [Cu(C(2)O(4))(C(4)H(12)N(2)O)], the Cu(II) ion has a slightly distorted square-pyramidal geometry, with a tridentate N-(2-hydroxy-ethyl)ethyl-enediamine (HydEt-en) and a bidentate oxalate (ox) ligand. The N atoms of the HydEt-en ligand and the O atoms of ox ligand form the basal plane, while the O atom of the ethanol group of the HydEt-en ligand is located in the axial position. The complex mol-ecules participate in a supra-molecular assembly through N-H⋯O and O-H⋯O hydrogen bonds between HydEt-en and ox ligands.

Tris(ethyl-enediamine)cobalt(II) sulfate.

Project description:The structure of the title compound, [Co(II)(C(2)H(8)N(2))(3)]SO(4), the cobalt example of [M(C(2)H(8)N(2))(3)]SO(4), is reported. The Co and S atoms are located at the 2d and 2c Wyckoff sites (point symmetry 32), respectively. The Co atom is coordinated by six N atoms of three chelating ethyl-enediamine mol-ecules generated from half of the ethyl-enediamine mol-ecule in the asymmetric unit. The O atoms of the sulfate anion are disordered mostly over two crystallographic sites. The third disorder site of O (site symmetry 3) has a site occupancy approaching zero. The H atoms of the ethyl-enediamine mol-ecules inter-act with the sulfate anions via inter-molecular N-H?O hydrogen-bonding inter-actions.
