Hk. Fun et al., A DIHYDRATE COMPLEX OF MOLYBDOSILICIC ACID AND HEXAMETHYLPHOSPHORAMIDE, [((CH3)(2)N)(3)PO](5)[H4SIMO12O40].2H(2)O, Acta crystallographica. Section C, Crystal structure communications, 54, 1998, pp. 327-329
The molybdosilicic acid residue, H4SiMo12O40, has the Keggin structure
, with M-O distances varying between 1.796 (4) and 2.112 (3) Angstrom.
In the hexamethylphosphoramide groups, all N atoms except one show a
planar coordination.
