Zb. Cao et al., STRUCTURE OF BIS(EPSILON-CAPROLACTAM)DINITRATODIOXOURANIUM(VI), Acta crystallographica. Section C, Crystal structure communications, 49, 1993, pp. 1942-1943
The results of the structure determination of the title compound, H-az
epin-2-one-O)di(nitrato-O,O')dioxouranium(VI), revealed that the urany
l ion is coordinated to six O atoms, two of which are from the carbony
l groups of the caprolactams and the other four are from the two nitra
te groups. Average U-O distances are 2.531 (7) (nitrate) and 2.360 (5)
Angstrom (carbonyl).
