Résumé |
{Two new organic-inorganic hybrid compounds of molybdenum(VI) (HDBU)(3)(NH4)[beta-Mo8O26] (.) H2O 1 and (HDBU)(4)[delta-Mo8O26] 2 have been synthesized and characterized by elemental analyses, FT-IR and UV-vis spectroscopies, and single-crystal X-ray diffraction (at 293 and 100 K. respectively). Compound I is obtained at room temperature by adding 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) on aqueous molybdate solution at pH = 5.7. Compound 2 is obtained hydrothermally from 1 (110 degrees C, 24 h, autogenous pressure). Compound I crystallizes in the triclinic crystal system, space group P1, with a = 11.2492(9)
