The structure of a [1,2,5]oxaselenazolo[2,3-b][1,2,5]oxaselenazole-7-seIV by X-ray crystallography and nuclear magnetic resonance spectroscopy
Abstract
A study of a [1,2,5]oxaselenazolo[2,3-b][1,2,5]oxaselenazole-7-SeIV by X-ray methods shows that most of the molecule is planar and that the oxygen atoms are held in close contact (2.017–2.030 Å) with the selenium atom.
