| Abstract: | The tetranuclear compound Mo2(O2C‐tBu)3]2(μ‐C2O4) ( 1 ) that is prepared from Mo2(O2C‐tBu)3]4 and oxalic acid, was reacted with MnI2 · 2THF to form the polyoxomolybdate compound Mn(CH3OH)6] Mo8O16(OCH3)8(C2O4)] ( 2 ) in a complex redox reaction. Crystals of 2 were analyzed by single‐crystal X‐ray diffraction showing a octanuclear polyoxomolybdate dianion in which the Mo=O moieties are alternately connected through μ‐oxo and μ‐methoxo units. Charge balance in 2 is realized by a manganese(II) cation that is octahedrally coordinated by methanol ligands. The crystal structure is dominated by strong hydrogen bond interactions of the O–H ··· O type of methanol molecules coordinated to manganese as well as additional methanol molecules in the crystal lattice. |
