Abstract

Abstract After a short survey of what is the present state of the cyclophosphates associated with the organic molecule NH 2(CH 2) 4NH 2, we report chemical preparation and crystal structure for a new example of such compounds. [NH 3(CH 2) 4NH 3] 2P 4O 12.2H 2O is monoclinic (S.G. : P2 1/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 P 4O 12 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.
