Sažetak
In the reaction of molybdenum(VI) oxide with oxalic acid and RCl(R = pyH and -picH), new dinuclear complexes of molybdenum(VI)R2 Mo2O5(C2O4)2(H2O)2 have been prepared. When molybdenum(VI)oxide was treated with aqueous solution of tetramethylammoniumoxalate complex, (CH3)4N 2 MoO3(C2O4) H2O was isolated. Theunknown crystal structure of (CH3)4N 2 Mo2O5(C2O4)2(H2O)2 wasdetermined from single crystal diffractometer data and refined to thefinal R value of 0.0317. When irradiated, this class of compoundsshows considerable photochromic properties. The photochemicalprocess is of the redox type: molybdenum(VI) centers are reduced tomolybdenum(V) moieties. The presence of molybdenum(V) specieswas confirmed by the ESR spectra.
