摘要：

Three metal molybdate hydrates, Fe(H2O)(2)(MoO4)(2)center dot H3O(FeMo), NaCo2(MoO4)(2)(H3O2)(CoMo) and Mn-2(MoO4)(3).2H(3)O(MnMo), were synthesized by the mixed-solvent-thermal methods and characterized by single-crystal X-ray diffraction. X-Ray photoelectron spectroscopy and bond-valence sums were applied to confirming the valance of Fe, Co, Mn and Mo. Thermo-gravimetric analysis and X-ray powder diffraction measurements indicate that the samples were converted to different structural compounds upon heating in air at 600 degrees C for 1 h. The magnetic properties of these compounds were studied. The dominant magnetic interactions are antiferromagnetic in nature. However, different synthesis conditions led to the diversity of magnetic properties of compound CoMo.
