article description
Crystalline peroxo molybdate(VI) complexes with imidazole are reported: (C 3 H 5 N 2 ) 2 [O{MoO(O 2 ) 2 H 2 O} 2 ] ( 1 ), MoO 2 (O 2 )(C 3 H 4 N 2 )2H 2 O ( 2 ) and K 2 MoO 2 (O 2 ) 2 (C 3 H 4 N 2 )4H 2 O ( 3 ). They represent the first peroxo metal compounds containing imidazole. IR spectra display characteristic ν(MoO) between 967 and 955 cm −1, and ν(OO) between 892 and 853 cm −1. The X-ray crystal structure of ( 1 ) shows the presence of a μ-oxo group bridging two pentagonal bipyramidal {MoO(O 2 ) 2 H 2 O} moieties, each hydrogen bonded to an essentially planar imidazolium cation via one of the oxygens of a coordinated peroxo group.
