	Abstract	Single crystals of the new compound Ba2Zn(B30 6)2 were obtained by using a B20 3 flux technique. They crystallize in an as yet unknown structure type. X-ray investigations led to space group Cj'-Pl (Nr.2) with lattice parameters a = 715.5(2), b = 720.5(2), c = 1178.9(4), a = 78.96(2)°, /3 = 85.45(2)°, j = 60.12(1)°, Z = 2. The structure is characterized by iso lated (B30 6)3_-rings and contains two ninefold coordinated Ba-sites. Zn2+ is tetrahedrally coordinated by oxygen. The relation to the crystal structures of high-temperature BaB20 4 and Ba2Ca(B30 6)2 is discussed.

	Title	A -P r 2S3, D -H o2S3 und E -Y b 2S3: Synthese und Einkristallstrukturuntersuchungen
	Abstract	The oxidation of reduced chlorides (MC12) or chloride-hydrides (MC1HV) of the lanthani des with sulfur (700-850 °C, 7 d, sealed tantalum capsules or evacuated silica vessels) usually results in the formation of the sesquisulfides M2S3 as the main products. In the presence of appropriate fluxes (e.g., alkali halides), the products often are obtained as single crystals, and the flux decides which modification is favoured. Ternary halides of the trivalent lanthanides with the corresponding alkali metal can mostly be found as the second components. Crystal growth and structural investigations of thus produced single crystals of Pr2S3 (from PrClH() 67 + S + NaCl, 5:5:1, A type: orthorhombic, Pnma (No. 62), Z = 4, a = 748.22(5), b = 405.51(3), c = 1560.74(9) pm, R = 0.024, Rw = 0.020), Ho^S, (from U -H o^S , + KI, 1:1, D type: mono clinic, P 2xim (No. 12), Z = 6, a = 1746.15(9), b = 400.23(3), c = 1012.43(6) pm, ß = 98.529(4)°, R = 0.041, Rw = 0.035), and YbiS3 (from T-Yb^S^ + KI, 1:1, E type: trigonal, R 3c (No. 167), Z = 6, a = 674.97(2), c = 1820.11(9) pm'. R = 0.019, Rw = 0.018) are reported here. In accordance with the lanthanide contraction, the trivalent cations (M3+) exhibit sulfur coordination numbers of 7 and 8 in A -P r 2S3, 6 and 7 in D -H o 2S3, and 6 in E -Y b 2S3 (corundum-type structure).

	Title	Eine unerwartete Synthese des Triphenyphosphazenium-chlorids, [(C6H5)3PNH2]+CI_ und eine Neubestimmung seiner Kristallstruktur
	Abstract	Triphenylphosphazenium chloride has been prepared by the reaction of triphenylphos-phine with trimethylsilylazide in impure, wet dichloromethane. Yields are improved as stoi chiometric quantities of w ater are added. Colourless crystals are obtained by recrystallization from the same solvent. The crystals are triclinic, space group P I, Z=2, a = 894,6(3), b -979,8(3), c = 1142,9(4) pm, a = 107,27(3), ß = 93,70(3), y = 92,97(3)°. In the solid state the compound exists as [(C6H 5)3PNH2]+ cations, and Cl-anions. Dimeric units are formed by H-bonding. The crystal structure contains one molecule CH 2C12 per one molecule (C6H 5)3PNH2C1. The cation has a slightly irregular tetrahedral geometry around the P-atom with a relatively short P-N bond.

	Title	(PPh4)4Sb8Br28 Tetraphenylphosphonium Ikosioctabromooctaantimonate(III), (PPh4)4Sb8Br28
	Abstract	The title compound was obtained by the reaction of PPh4Br, Sb2Se3, and bromine in dichloro-methane. Its crystal structure was determined by X-ray diffraction. Crystal data: a = 1249.1(2), b = 1307.8(2), c = 2152.3(4) pm, a = 102.93(2), ß = 100.83(2), 7 = 100.42(2)°, Z = 2, triclinic, space group P I . (PPh4)4Sb8Br28 is isotypic with (PPh4)4Sb8I28. The Sb8Br284~ ion can be taken as the association product of eight SbBr3 molecules with four B r-ions. Each Sb atom has a distorted octahedral coordination with three shorter (252 to 274 pm) and three longer (300 to 353 pm) Sb-Br bonds. The octahedra share common edges in two parallel rows of four octahedra each. The arrangement of the 28 bromine atoms corresponds to a section of a closest packing of spheres.

The last step is the ammo-nolysis of [C13PNPC13]C1. Single crystals of 1,1,1,3,3,3-hexaamino-1 A \ 3As-diphosphazenium chloride were obtained from an acetonitrile solution in a temperature gradient between 60 °C and room temperature. Between room temperature and -1 0 0 °C [(NH2)3PNP(NH2)3]C1 is sub ject to a phase transition. Therefore, the crystal structure was determined by single crystal X-ray methods at room temperature (P i, a = 584.7(1) pm, b = 732.1(1) pm, c = 1092.0(2) pm. q = 71.05(3)°, ß = 76.36(3)°, 7 = 89.83(3)°, Z = 2, R = 4.75 %, wR = 2.47 %). The cation [(NH2)3PNP(NH2)3]+ is built up by two corner sharing PN4 tetrahedra. Remarkably short P-N bonding distances have been observed and both PN4 tetrahedra exhibit a significant distortion resulting in two large and four small N-P-N bond angles.

	Title	Ba2Na(CN2)(CN)3, ein neues Cyanamid-cyanid mit interpenetrierenden Teilstrukturen Ba2Na(CN2)(CN)3, a Novel Cyanamide Cyanide with Interpenetrating Substructures
	Abstract	Ba2Na(CN2)(CN)3 was obtained by the reaction of Ba2N with melamine and NaCN at 700 °C. The compound was structurally characterized by single-crystal X-ray investigations (Fd3m, a = 1518.8(3) pm, Z = 16). In the crystal structure the Ba"+ ions form a cubic close packed arrangement, the Na+ and the CN2_ ions occupy the octahedral interstices. The CN-ions are located within the close packed Ba2+ layers. The unit cell of Ba2Na(CN2)(CN)3 contains two interpenetrating substructures of the zinc-blende structure type, building up a variant of NaTl. A reversible phase transition has been observed during cooling of the compound. Whereas the Ba2(CN2)(CN)3 sublattice remains nearly unaffected in this process, the Na+ ions of the low-temperature phase are statistically distributed on two crystallographic positions.

	Abstract	From the ternary system Mn(S 0 4)n/2 / S 0 3 / H20 (Mn+ = Zr4+, Ti3+) two new acid metal sulfates, Ti(H50 2)(S 0 4)2(H20)2 and Zr(H30) 2(S 0 4)3, have been synthesized and structurally characterized. Ti(H50 2)(S 0 4)2(H->0)i crystallizes in the orthorhombic space group Pnma with cell parameters a = 9.858(5), b = 18.32(2), c = 5.437(7)Ä (Z = 4); Zr(H30) 2(S 0 4)3 crystallizes in the triclinic space group PI with cell parameters a = 5.092(2), b = 8.533(3), c = 12.388(6)A, a = 92.95(3)°, ß = 90.89(3)°, 7 = 94.35(3)° (Z= 2). In the titanium compound there are slightly distorted T i0 6 octahedra with T i-0 distances between 1.99 and 2.09 A which are sharing corners with S 0 4 tetrahedra. Through hydrogen bonds layers are formed perpendicular to the 6-axis. These layers are connected by H30 + ions only. The structure of Zr(H30) 2(S 0 4)3 consists of three different S 0 4 tetrahedra and distorted Zr07 polyhedra which are connected via common corners and edges to form columns parallel to the a-axis. The Z r-0 distances vary from 2.13o to 2.18A for equatorial positions, significantly longer than the axial Zr-O distances with 2.05A.

	Title	R obert
	Abstract	The ternary compound Ce8Pd24Sb is very close in composition to the intermediate valent binary CePd3. A single crystal study yielded a cubic cell with a = 8.461 (1)A, Pm3m symmetry with wR2 = 0.0412 based on 1453 reflections (222 unique) and 16 parameters. This new structure type is composed of distorted perovskite and Cu3Au subcells arranged with the perovskite-like units centred on the corners of the cube. Fitting the magnetic susceptibility data above 100K to a Curie-Weiss expression yielded a Weiss constant of -15(3)K (anti ferromagnetic) and an effective high temperature moment per cerium of 2.45(4)/<B indicating trivalent cerium. No ordering was observed above 3K.

	Title	Two Examples of Partial and Total Defects in the B a«Ln2Mo4O i6-Type: BaCu0 41 ■o,59Pr2Mo4 0 16 and BaBYb2Mo4Ojg
	Abstract	Single crystals of (I) BaCu0.4iPr2M o4O 16 and (II) BaYb2M o40 16 have been prepared by flux technique. Both compounds crystallize with m onoclinic symmetry, space group C2h-C 2 /c with (I): a = 5.352(11), b = 12.888(2), c = 19.399(4) A; ß = 90.89(3)°; (II): a = 5.181(7), b = 12.467(3), c -19.350(3) Ä , ß -91.93(2)°, Z = 4. The crystal structure is characterized by i [ B a M 0 12]-chains along [010]. In the first case the M positions are occupied by copper by about 41%, in the second case these positions remain com pletely unoccupied. With respect to the crystal chemistry of the reference compound Ba(Cu0.22Mg() 78)Nd2Mo4O 16 all substan ces of the composition BaLn2M o40 16 should be written as Ba»Ln2Mo40 16 indicating the holes in th e^ B a M O i^ -c h a in s by ■.
