	Title	Monoheteroarylborate [1]
	Abstract	The heteroaryl borates Li[C4Me4NBH3] (6) and Na[C3H 3N2(BMe3)2]* 2 C4HgO (8) are ob tained by treatment of Li[C4Me4N] and Na[C3H3N2] with Me2S • BH3 and BMe3, respectively. The X-ray structure of [Na(C4H 80) 6][C3H 3N 2(BM e3)2] (10) is reported.

	Title	Die Synthese und Kristallstruktur des Borat-Phosphats: a -Zn3(B0 3)(P04) Synthesis and Crystal Structure of the Borate-Phosphate: Q-Zn3(B 0 3)( P 0 4)
	Abstract	Single crystals of the compound a -Z n 3(B 0 3)(P 0 4) were obtained at 1050 °C by using B20 3, P20 5 and Z n C 0 3 as starting materials and subsequent cooling to 600°C with 20°C/h. X-ray investigations on single crystals yield a new crystal structure in the monoclinic space group Cm -(Nr. 8) with a = 972.5(2); b = 1272.0(3); c = 487.4(3) pm; 0 = 1 1 9 .8 0 (4)°; Z = 4. The structure contains isolated trigonally planar B 0 3 and tetrahedral P 0 4 units which are not joined together. Zinc occupies three crystallographically different point positions and is trigonal-bipyramidally, tetragonal-pyramidally or distorted tetrahedrally coordinated by oxygen.

	Title	AgSrfByO^]: Das erste wasserfreie quaternäre Silber(I)-Borat mit vierfach koordiniertem Silberion und einem neuartigen Boratanion AgSr[B70 12]: The First Anhydrous Quaternary Silver(I)-Borate with Fourfold Coordinated Silver Ion and a New
	Abstract	Single crystals of AgSr[B70 , 2] were obtained by using a B20 3 flux-technique and Ag2C 0 3 and SrC 03 as starting materials in a silver ampoule at 800 °C. X-ray investigations on single crystals led to the space group C 2/c with a = 664.2(5); b = 1153.6(3); c = 2198.0(6) pm; ß = 92,52(3)°; Z = 8. Ag+ is fourfold coordinated by oxygen atoms and forms distorted A g04 tetrahedra while Sr2+ has nine nearest neighbours. The compound contains a hitherto unknown two dimensional borate anion [B70 i 2]3-which contains four trigonal planar B 0 3 groups and three B 0 4 tetrahedra per unit.
