title: catena-Poly[[heptakis(dimethylformamide-kappaO)di-mu4-oxo-tetra-mu3-oxo-hexadeca-mu2-oxo-tetraoxolanthanum(III)octamolybdenum(IV)]-mu-sodium(I)].
abstract: The title compound, [NaLaMo(8)O(26)(C(3)H(7)NO)(7)](n), contains infinite chains of [Mo(8)O(26)](4-) units supporting dimethylformamide-coordinated La(III) cations and linked by Na(+) cations. The lanthanum center adopts a nine-coordinate geometry and the Na atom is sandwiched between two beta-[Mo(8)O(26)](4-) units.
