DPA(di-no-propylammine). Structurally investigated by synchrotron single crystal

X-ray diffraction at room temperature. In order to determine the detailed structure,

high flux synchrotron X-ray(0.7997Å wavelength)was used at beamline 4A at Pohang

Accelerator Laboratory. Preliminarily results show that crystallographically

orthorhombic space group Pnma with a=15.464(9)Å, b=14.136(22)Å, c=14.493(1)Å

and phosphate seems to coordinate covalent bond with 6 oxygen.
