Abstract:
Single crystals of [(CHs)2NCHO]4H4[VWIIVIO40].2[(CH3)2NCHO].2H20 have been obtained, and the crystal structure of the compound determined. The dimensions of the monoclinic unit cell are: a = 11.557(7),
b = 15.834(7), c = 16.491(6) Å, beta = 104.06(4) °, V = 2927Å3, Z = 2, space group P21/n. The structure has been refined as far as R = 0.076 for 2210 independent reflections (Syntex P21 diffractometer, МоКα-radiation,
8/28 scanning). The structure is made up of heteropolyanions of the Keggin type, disordered in two positions related by a center of symmetry, and dimethylformamide molecules and water molecules. All the units are joined by a branched system of contacts to form a three-dimensional framework. The vibrational (IR and laser Raman) spectra, which can be used to identify compounds of this type, have been studied.
