The hybridized lanthanide-contg. molybdenum blue (Ln-MB) wheel Na4[Mo2O2(OH)4(C6H4NO2)2]2[Mo120Ce6O366H12(OH)2(H2O)76]~200H2O ({Mo2(C6H4NO2)2}2{Mo120Ce6}) was assembled in an aq. one-pot synthesis. The Ln-MB was hybridized with 2-picolinic acid through the generation of the organometallic counter-ion [Mo2O2(OH)4(C6H4NO2)2]2+. Control expts. demonstrated that the position of the carboxylic acid group (2-position to the N atom) in the hybridization component is crit. in yielding single crystals of Ln-MB. In addn. to single-crystal X-ray diffraction (XRD) anal., which revealed a 'Japanese rice-ball'-shaped Ln-MB as the anion, elemental analyses, IR spectroscopy, and thermogravimetric anal. (TGA) were performed to confirm its structure and compn. Bond-valence-sum calcns. (BVS) revealed that {Mo2(C6H4NO2)2}2{Mo120Ce6} is composed of a 24-electron reduced anionic ring, which was confirmed by Vis-NIR spectroscopy.
