Abstract
Thallium(I) oxalohydroxamate 1, Tl(HONHCOCONHO), and malonohydroxamate 2, Tl(HONHCOCH2CONHO), have been characterized as acid salts of type A2 and B2, respectively, using single-crystal X-ray diffraction. In 1 the co-ordination polyhedron around the TlI can be described as a distorted dodecahedron; the eight Tl–O bonds are divided into sets of six short and two long, the latter lying at one side of the TlI the lone-pair electrons of which are stereoactive. In 2 the co-ordination environment of TlI is square pyramidal with the lone-pair electrons oriented in the axial direction.Keywords
