Synthese und Untersuchung der Lanthanoidoxidnitrate

The lanthanide oxide nitrates LnONO3 with Ln = Pr, Nd, and Sm-Yb were synthesised by thermal decomposition of hydrated lanthanide nitrates. The compounds were refined isotypically to YONO3 in the tetragonal space group P4/nmm and the structure is closely related to the PbFCl-type. Because of the orientational disorder of NO3− in this structure refinement a possible superstructure is discussed. ...

Adverse reactions to khat that have been reported in the literature include myocardial infarction and reversible vasoconstriction syndrome. The active ingredient, cathinone, is a naturally occurring beta-ketone amphetamine that may be responsible for this severe catecholaminergic response. Here we report a c...
