Metal complexes of thio-hydroxamic acids. Part I. Crystal structure of bis(thioacetohydroxamato)nickel(II)

Abstract

The crystal structure of bis(thioacetohydroxamato)nickel(II) has been determined by three-dimensional X-ray diffraction methods. There are four molecules in the unit cell, a= 15·59, b= 5·78, c= 9·53 Å, with space group P2₁2₁2₁. The atomic co-ordinates were determined by Fourier and least-squares methods. The final R value over the 1181 independent reflections was 0·11. The nickel complex of thioacetohydroxamic acid forms five-membered chelate rings in which the metal is co-ordinated to sulphur and oxygen and the chelate rings are cis. Each ring is planar; the angle between the normals to the planes is 9·6°.
