Abstract
After a short survey of what is the present state of the cyclophosphates associated with the organic molecule NH2(CH2)4NH2, we report chemical preparation and crystal structure for a new example of such compounds. [NH3(CH2)4NH3]2P4O12.2H2O is monoclinic (S.G. : P21/n), with Z = 2 and the following unit-cell parameters : a = 7.6728(8) Å, b = 18.962(3) Å, c = 7.9789(9) Å β = 111.751(9)°. Bidimensional layer arrangement of P4O12 rings connected to the water molecules thanks to weak H-bonds run parallel to the ab plane. The organic groupements located between these inorganic planes perform the three-dimensional cohesion by NH····O hydrogen bonds.
在对与有机分子NH2(CH2)4NH2相关的环磷酸盐的现状进行了简短的调查之后，我们报告了这种化合物的新例子的化学制备和晶体结构。[NH3(CH2)4NH3]2P4O12.2H2O为单斜晶(S.G.: P21/n)， Z = 2，单元胞参数为:a = 7.6728(8) Å， b = 18.962(3) Å， c = 7.9789(9) Å β = 111.751(9)°。由于弱氢键与ab平面平行，P4O12环的二维层状排列与水分子相连。位于这些无机平面之间的有机基团通过NH····O氢键进行三维内聚。
