Abstract:

Inorganic-organic hybrid compounds exhibit interesting properties in several application areas. In this regard, chemical preparation and characterization by X-ray diffraction, thermal analysis, and IR spectroscopy are given for a new organic cation diphosphate [4-CH 3 OC 6 H 4 CH 2 NH 3 ] 4 P 2 O 7 ·6H 2 O. This later crystallizes in a C2/c unit cell with a = 38.238(6)Å, b = 6.453(1)Å, c = 16.942(7)Å; β = 97.60(4)°; Z = 4; and V = 4144(2)Å 3 and D x = 1.377 g·cm −3 . Its crystal structure has been determinated and refined to R = 0.044, using 7978 independent reflections. This atomic arrangement consists of inorganic layers built up from P 2 O 7 4− anions and water molecules. On these layers, which are parallel to the (b, c) planes, the (4-CH 3 OC 6 H 4 CH 2 NH 3 ) + cations are anchored through multiple hydrogen bonds.
