Synthesis and X-ray structure of a formylated octamolybdate cluster [(HCO)2(Mo8O28)]6–
Abstract
Reaction of formic acid with aqueous (NH4)6–[Mo7O24]yields the compound (NH4)3[(HCO)(Mo4O14)]·H2O which has been shown by X-ray crystallography to contain the discrete [(H2Mo8O28)]6– anion; this anion is related to the [H2Mo8O28]6– anion by replacement of its surface-bound protons with formyl groups.
