The title compound, (NH4)(4)(H6ZnMo6O24).6H(2)O, exhibits a structure
with six MoO6 octahedral edge-sharing units surrounding a central ZnO6
octahedron, with all metal atoms in a common plane. The average Zn-O
distance is 2.081 (5) Angstrom, while the average Mo-O distances are 2
.240 (15), 1.946 (11) and 1.711(12) Angstrom for four-, two- and singl
e-coordinate O atoms, respectively.
