Xl. Jin et al., SYNTHESIS AND CRYSTAL-STRUCTURE OF A NOVEL KEGGIN-TYPE ISOPOLYOXOMOLYBDATE [BU(4)N](6)[H3O](2)[MO13O40](2), Polyhedron, 13(15-16), 1994, pp. 2439-2441
Solid-state reaction of (NH4)(6)Mo7O24.4H(2)O with Bu(4)NBr and NH2OH.
HCl at low temperature yields an isopolyoxomolybdate [Bu(4)N](+)(6)[H3
O](+)(2)[Mo13O40](4-)(2), the structure of which has been determined b
y X-ray crystallography. The title compound contains two [Mo13O40](4-)
anions which have different symmetry. Both anions have Keggin-type st
ructures with a molybdenum atom centre.
