| Abstract: The intermolecular compound H4GeW12O40·5C6H7N·CH3CN was synthesized from germanotungstic acid γ-methylpyridine. Its crystal structure has determined by X-ray analysis. It alongs to the orthorhombic, space group P212121, with a=13.533(5), b=20.835(5), c=21.859(7)?, V=6164(3)?3, Dc=3.650 Mg/m3, Z=4. The final residue factor, R=0.0534, was got from final refinement for 3934 observed reflections by full-matrix least-squares method. |
