✦ Synopsis

The crystal structures of three dinuclear diperoxo compounds have been determined from single-crystal X-ray diffraction data. All title compounds crystallize as yellow needle-shaped crystals in the triclinic space group P 1(2). ( 1

where 2-MepyH denotes 2-methylopyridine, crystallize with a = 6.733(5), b = 8.364(5), c = 13.984(5) A ˚, a = 73.702(5), b = 87.647(5), c = 85.216(5)°, Z = 2. (3) (2-MepyH,Na){O[MoO(O 2 ) 2 H 2 O] 2 } crystallize with a = 6.765(5), b = 8.421(5), c = 13.815(5) A ˚, a = 74.203(5), b = 84.775(5), c = 71.371(5)°, Z = 2. Results of crystal structure determination, investigations of the stability of the obtained diperoxo compounds at room temperature, and the results of IR and TG/DSC studies are presented in this paper. The dinuclear diperoxo compounds are relatively stable at room temperature, in elevated temperatures they can decompose in explosive manner.
