説明

The crystal structure of melamine diborate (C3N6H6⋅2H3BO3), well known as raw material of boron nitride, was determined by single crystal X-ray analysis. Molecules are packed in a monoclinic crystal system, space group P21/c, with a=0.3596(1)nm, b=2.0111(2)nm, c=1.41092(9)nm, β=92.12(2)°, Z=4 and crystal density is 1.627g/cm3. Molecules in the crystal are linked together by hydrogen-bonds, and form spirally stacked quasi-sheets parallel to a-axis. Bond lengths of hydrogen-bonds range from 0.181(2)nm to 0.209(2)nm. The crystal shows needlelike habit and its longitudinal direction is also parallel to a-axis. The preferred orientation, which was elucidated from powder X-ray diffraction pattern, is presumably due to the needlelike habit and is attenuated by grinding.
