X-Ray Crystal Structure of Trans-Bis(monoethanolamine) Bis(saccharinato)nickel

Abstract

The crystal structure of trans-bis(monoethanolamine)bis(saccharinato)nickel(II), [Ni(C<inf>7</inf>H<inf>4</inf>NO<inf>3</inf>S)<inf>2</inf>(C<inf>2</inf>H<inf>7</inf>NO)<inf>2</inf>], has been determined from X-ray diffraction data. The metal complex is monoclinic, with a = 11.0555(5), b = 8.9103(4), c = 11.3890(5) Å, β = 105.0230(10)°, Z = 2, and space group P2<inf>1</inf>/c. The structure consists of individual molecules. Two monoethanolamine molecules and two saccharinate anions coordinate the nickel atom forming a distorted octahedron. The monoethanolamine molecules act as a bidentate ligand and form five-membered trans chelate rings, which constitute the plane of the coordination octahedron, while two saccharinate ions behave as a monodentate ligand occupying the axial positions. Intermolecular hydrogen bonds link the molecules to form a three-dimensional infinite structure.
