Kristallstrukturuntersuchungen von Hauptgruppen-Nitriden mittels Pulverbeugung
In this thesis new nitrides and imides were investigated by powder diffraction methods. The crystal structures of a series of nitridophosphates and nitridocarbonates which were available only as powder were solved by direct methods after indexing and extraction of the integrated intensities. By neutron powder diffraction on the one hand hydrogen was localized in an imide, on the other hand the elements nitrogen and oxygen, which are difficult to distinguish by X-ray diffraction, were discerned in oxonitridophosphates and oxonitridosilicates. Thus the importance of the powder diffraction for nitrides could be proved.
