Nitridoborate der Lanthanoide enthalten BN x -Einheiten, in denen Bor analog zur Struktur des hexagonalen Bornitrids (a-BN) zur Bildung der Koordinationszahl drei tendiert. Die Koordinationszahl vier ist nur durch die kubische Form von Bornitrid belegt (b-BN). Die Koordinationszahl zwei tritt in Ver
Single crystals of the lanthanoide nitrido borates Ln 3 B 2 N 4 (Ln = La±Nd) and La 5 B 4 N 9 have been obtained from reactions of lanthanoide metal powder, lanthanoide nitride powder, and hexagonal boron nitride in calcium chloride melts. The isotypic compounds Ln 3 B 2 N 4 belong to the space grou
A novel borophosphate-hydrate, (Ni 3±x Mg x )-[B 3 P 3 O 12 (OH) 6 ] ´6 H 2 O (x » 1.5), has been prepared by hydrothermal synthesis (T = 170 °C) from a mixture of NiCl 2 ´6 H 2 O, Mg(OH) 2 , B 2 O 3 and H 3 PO 4 . The crystal structure was determined at 293 K from single-crystal X-ray diffraction d
