	Title	Zur Kristallchemie eines Silber-Cadmium-Oxovanadats: AgCdV04 On the Crystal Chemistry of a Silver Cadmium Oxovanadate: A gC dV 04
	Abstract	Single crystals of A gC dV 04 have been prepared in closed silver tubes using V20 5 as a flux. The light-orange crystals sho\v orthorhom bic symmetry, space group D2h-Pnm a, a = 9.786(2), b = 6.994(1), c = 5.439(1) A, Z = 4. The hitherto unknown A gC dV 04 is related to the Olivine structure but isotypic to Ag2C r 0 4 and NaCd4(V 0 4)3 respectively. The differences in crystal chemistry between the Olivine type, NaCd4(V 0 4)3 and A gC dV 04 are discussed.

	Title	Zur Synthese und Kristallstruktur von Kupfercadmiumpyroboratoxid: Cu2Cd(B20 5) 0 Synthesis and Crystal Structure of Copper Cadmium Pyroborate Oxide: Cu2Cd(B20 5) 0
	Abstract	Single crystals of the new compound Cu2C d(B20 5) 0 have been prepared by B 20 3/V 20 5 flux technique in a closed silver tube. Their structure is isotypic with Cu2C o(B 20 5) 0 but its preparation is quite different. X-ray investigations on single crystals led to the space group C \|h-P 2 !/c (Nr. 14), a = 339.9(2); b = 1509.8(2); c -927,0(1) pm; ß = 93.19(1)°; Z -4. The structure contains isolated B 2O s groups and oxygen that is not coordinated to boron. Cad mium is octahedrally coordinated by oxygen, while copper exhibits a nearly square planar or a fivefold pyramidal coordination.

	Title	Synthese und Kristallstruktur einer mit dem Johillerit verwandten
	Abstract	Single crystals of C dC u^M gx.5Pbo.5V30 12 have been prepared in closed steel tubes using V 20 5 as a flux. The orange crystals show monoclinic symmetry, space group C2h-C 2 /c , a = 12.417(5), b = 12.983(6), c = 6.911(3) Ä , ß = 113.02(1)°, Z = 4. CdCu1.5Mg1.5PbojV30 12 reveals a relationship to the Johillerite type, but it is characterized by an additional point position for cadmium, situated betw een the square planar C u 0 4 polygons of the Johillerite structure.
