C. Wu et al., [Na-4(H2O)(7)][Pe(OH)(6)Mo6O18]: a new [12] metallacrown-6 structure with an octahedrally coordinated iron at the center, SCI CHINA B, 44(1), 2001, pp. 49-54
The reaction of an aqueous solution of sodium molybdate with iron powder at
low pH (similar to0.184) gives rise to the formation of a six-member Mo ri
ng-shape cluster with an Fe (II) encapsulated at the center, [Na-4(H2O)(7)]
[Fe(OH)(6)Mo6O18](1), which is further linked to a remarkable three-dimensi
onal network via sodium ions.
