In the first Fe site, Fe(1) is bonded to one O(2), one O(3), one O(5), one O(7), and one Cl(2) atom to form distorted FeClO4 trigonal bipyramids that share corners with two equivalent Mo(1)O4 tetrahedra and corners with two equivalent Mo(2)O4 tetrahedra. In the second Fe site, Fe(2) is bonded to one O(1), one O(4), one O(6), one O(8), and one Cl(1) atom to form FeClO4 trigonal bipyramids that share corners with two equivalent Mo(1)O4 tetrahedra and corners with two equivalent Mo(2)O4 tetrahedra.
