trans-Diaqua­bis­(dl-valinato-κ2 NO)nickel(II)

摘要

In the title complex, [Ni(C5H9NO2)2(H2O)2], the Ni^II atom, located on a centre of inversion, is trans-coordinated by two O atoms and two N atoms from d-bidentate valine and l-bidentate valine ligands and two water O atoms in an octa­hedral geometry. In the crystal, the discrete mononuclear units are linked into a three-dimensional network via O—H⋯O and N—H⋯O hydrogen bonds. C—H⋯O inter­actions are also observed.
