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.

(H/sub 3/NCH/sub 2/CH/sub 2/NH/sub 3/)HPO/sub 4/ (Ⅰ) 화합물을 수열법으로 최초로 합성하고 단결정 X-선 회절법으로 구조를 규명하였다. 이 화합물은 단사정계 , 공간군 P2/sub 1//c, 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＝4로 결정화되었으며, 1141 개의 독립적인 회절 반점에 대한 최종 신뢰도 인자 R/sub 1/ 및 ωR/sub 2/값은 각각 0.0295 및 0.0811이었다. 화합물 (Ⅰ)은 수소결합으로 연결된 3차원의 그물 구조를 갖는다.
