abstract The oxodiperoxo complex MoO(O-2)(2)(tbbpy) (tbbpy = 4,4'-di-tert-butyl-2,2'-bipyridine) was isolated from the reaction of MoO2Cl2(tbbpy) in water under microwave-assisted heating at 120 degrees C for 4 h. The structure of the oxodiperoxo complex was determined by single crystal X-ray diffraction. The Mo-VI centre is seven-coordinated with a geometry which strongly resembles a highly distorted bipyramid. Individual MoO(O-2)(2)(tbbpy) complexes are interdigitated along the [010] direction to form a column. The crystal structure is formed by the close packing of the columnar-stacked complexes. Interactions between neighbouring columns are essentially of van der Waals type mediated by the need to effectively fill the available space.
