Bis(acesulfamato-κO,N)bis­(3-methyl­pyridine)Copper(II)

Abstract

In the crystal structure of the title compound (systematic name: bis[6-methyl-1,2,3-oxathiazin-4(3H)-one 2,2-dioxide-(1-)- κ2N3,O4]bis(3-methylpyridine)copper(II)}, [Cu(C<inf>4</inf>H<inf>4</inf>-NO<inf>4</inf>S)<inf>2</inf>(C<inf>6</inf>H <inf>7</inf>N)<inf>2</inf>], the CuII centre resides on a centre of symmetry and has an octahedral geometry that is distorted both by the presence of four-membered chelate rings and because of the Jahn-Teller effect. The equatorial plane is formed by the N atoms of two methylpyridine ligands and by the more basic O atoms of the acesulfamate ligands, while the weakly basic N atoms of these ligands are in elongated axial positions with a misdirected valence. The crystal is stabilized by two intermolecular C-H⋯O interactions involving the methyl and CH groups, and the sulfonyl O atoms of the acesulfamate group. © 2006 International Union of Crystallography.
