✦ Synopsis


Structural phase transitions in zinc(I1) hexaaquonitrate have been studied below 300 K by Raman spectroscopy and X-ray powder diffraction. Changes of A1 nitrate and 0 -H bands together with diffractograms as functions of temperature are presented. The compound undergoes several transitions and four previously unreported modifications were found and characterized.

Die strukturellen Phaseniibergange in Zn(H,O),, unterhalb 300 K wurden mit Hilfe der

Rontgen-Pulverdiffraktometrie und der Raman-Spektroskopie untersucht. hderungen in den Banden der AI(NO,),-und OH-Gruppen in Abhangigkeit von der Temperatur werden mitgeteilt. Die Verbindung zeigt einige strukturelle Phasenubergange. Vier neue, friiher nicht beschriebene Modifikationen wurden entdeckt und charakterisiert.
