Abstract
The title compound, (H/sub 3/NCH/sub 2/CH/sub 2/NH/sub 3/)HPO/sub 4/ (Ⅰ), has been synthesized by hydrothermal technique for the first time and its novel structure analyzed by X-ray single crystallography. The compound (Ⅰ) crystallizes in the monoclinic system, P2/sub 1//c space group with a=10.209(1), b=7.891(1), c= 8.039(1) (equation omitted), β= 92.138(9)°, V=: 647.2(2) (equation omitted), Z=4, R/sub 1/=0.0295 and ωR/sub 2/=0.0811 for 1141 independent reflections. The compound (Ⅰ) is interconnected to give a three-dimensional network through hydrogen-bonding interactions.
