Abstract:	The syntheses and structures of the two mixedvalence crystalline molybdenum blue compounds Na₂₆[Mo₁₄₂O₄₃₂(H₂O)₅₈H₁₄] · ca. 300 H₂O ( 1 ) (containing the maximal number of well defined defects which influence the overall structure and the reactivity of the anionic cluster) and Na₁₆[(MoO₃)₁₇₆(H₂O)₆₃(CH₃OH)₁₇H₁₆] · ca. 600 H₂O · ca. 6 CH₃OH ( 2 ) (obtained in an optimized high-yield synthesis) are reported with reference to the critical conditions required for the isolation of corresponding crystalline materials.
