(Acetato-O,O')[tris(2-aminoethyl)amine-N,N',N'',N''']nickel(II) Perchlorate

The X-ray structure analysis of the title compound, [Ni(C₂H₃O₂)(C₆H₁₈N₄)]ClO₄, reveals it to consist of a distorted octahedral entity, with the Ni^II atom coordinated by four N atoms from a tris(2-aminoethyl)amine (tren) ligand and two O atoms from an acetate anion. The acetate anion coordinates to Ni^II as a bidentate ligand forming a four-membered ring, with the two O atoms chelating in different manners, resulting in different C-O and Ni-O bond distances.
