摘要

Single crystal X-ray diffraction study of glycine phosphite C2H5NO2 center dot H3PO3 was performed (monoclinic, space group P2(1)/c, a = 7.401(3) angstrom, b = 8.465(3) angstrom, c = 9.737(3) angstrom; beta = 100.73(5)degrees, Z = 4). It has been found that one of hydrogen atoms is located at the centre of symmetry forming two strong hydrogen bonds to yield H4P2O6-2 dimers, while another hydrogen atom is statistically disordered over two positions and organizes the dimers into an infinite corrugated chain. The ordering of this hydrogen atom position and/or displacement of the other one from the centre of symmetry will lead to the loss of symmetry centre and lowering of the point group symmetry from C-2h to piezo-active group C-2 or C-s.
