	Title	von Antimontribromid mit Biphenyl, 2 SbBr3 * C12H10 The Crystal Structure of the 2 : 1 Adduct of Antimony Tribromide with Biphenyl, 2SbBr3-Ci2Hio
	Abstract	The crystal structure of 2 SbBr3 • biphenyl consists of pyramidally shaped SbBr3 molecules and planar biphenyl molecules which form a centrosymmetric complex through bonding of the Sb atoms to the phenyl rings. The distance of the Sb atoms to the phenyl ring planes is 323 pm. Taking into account intramolecular bonds Sb-Br at an average of 250.9 pm, an intermolecular Sb---Br contact at 369.5 pm and the .-r-donor-acceptor inter-action the Sb coordination is distorted -octahedral. The structure is discussed with regard to related compounds.

	Title	Malonenamidoxim, Nickelkomplexe und deren ßeaktionsprodukte mit Sauerstoff und Kohlendioxid: Vergleichende Strukturuntersuchungen Malonenamide Oxime, Nickel Complexes, and their Reaction Products with Oxygen and Carbon Dioxide: Comparative Structural Studies
	Abstract	Malonenamide oxime [HONC(NH2)CH2C(NH2)NOH = C3H8N402] (1), its bis-chelate complex with Ni(II) [Ni(C3HyN402)2] (2) and an ethanol solvate of this complex [Ni(C3H7N402)2 • 0.6 C2H5OH] (3) are characterized by X-ray structure analysis, as well as a paramagnetic tris-complex [Ni(C3H7N402)2(C3HsN402)] (4), which forms a catena structure in the crystal. The molecular structures of two reaction products of 2 with air are described: [Ni(C3H5N403)2(H20)2] • 4 H20 (5) has formed by oxidation of the methylene groups and may be taken as a complex of mesoxalamide oxime; [NiCsHieNsOs] • 6 H20 (6) has a macrocyclic ligand which is a derivative of orthocarbonic acid, formed by addition of carbon dioxide to the oxime groups.

	Title	Röntgenstrukturbestimmung von A1C13-Pyridin-Addukten: Der strukturelle Aufbau im fra7is-Dichlorotetrakis(pyridin)aluminium(III)- Tetrachloroaluminat(III) und im Trichlorotris(pyridin)aluminium(III) X-ray Diffraction Study of AICI3-Pyridine Adducts: The Crystal Structure of 7ra/?s-Dichlorotetrakis(pyridine)aluminium(III)tetrachloroaluminat(III) and of Trichlorotris(pyridine)aluminium(III)
	Abstract	Crystals of [A1(C5H5N)4C12][A1C14] are orthorhombic, Pna2lf Z = 4, a = 18.522(7), b = 15.141(5), c = 9.593(3) A, V = 2690(2) A 3 , Dc = 1.440 g/cm 3 . The structure has been solved from 5968 diffractometer measured intensities and refined by full-matrix least squares to RW(F) = 0.032. The crystal structure shows the complex to be £ra»s-dichloro-tetrakis(pyridine)aluminium(III) tetrachloroaluminat(III). The mean trans Al-Cl-and trans Al-N-distances in the octahedron are 2.279(3) and 2.070(4) A, respectively. Crystals of Al(C5H5N)3Cl3 are monoclinic, P2i/c, Z = 4, a = 7.261(2), b = 29.961(4), c = 8.624(1) A, ß = 98.12(2)°, V -1857(1) A 3 , D0 = 1.326 g/cm 3 . The structure has been solved from 4707 diffractometer measured intensities and refined to RW(F) = 0.028. The crystal structure shows octahedral complexes AICI3 • 3 (C5H5N) with trans geometry. The Al-N-distance trans to chlorine (2.096(2) A) is significantly longer than the two other Al-N-distances (mean 2.072(2) A).

	Title	Oxotrihalogenoselenate(IV)
	Abstract	Darstellung, Struktur und Eigenschaften von P(C6H5)4SeOCl3, P(C6H5)4SeOBr3 und As(C6H5)4SeOBr3 Oxotrihalogenoselenates(IV): Preparation, Structure and Properties of P(C6H5)4SeOCl3, P(C6H5)4SeOBr3 and As(C6H5)4SeOBr3 The novel oxotribromosolenate(IV) SeOBr3~ anion was prepared from the reaction of stoichiometric quantities of SeOBi'2 and bromide in acetonitrile solution, and it was isolated as the tetraphenylphosphonium and -arsonium salts in crystalline form. For the synthesis of the analogous SeOCl3 _ as P(C'6H5)4SeOCl3, SeCl4 was reacted in the presence of a small quantity of H«() with P(CeH5)4Cl in acetonitrile. Complete N-ray structural analyses of P(C6H5)4SeOCi3 (space group P I, a = 10.981(3), b = 11.059(3), c = 10.358(3) A, a = 73.77(2)°, ß = 83.33(2)°, -/ = 80.51(2)°, V -1187.9(6) A 3) and of P(C6H5)4SeOBr3 (space group P 2i/c, a = 11.719(4), b = 16.088(4), c = 13.124(4) A, ß = 94.72(3)°, V = 2466(1) A 3) show dimeric centrosymmetric Se202Cl6 2-and Se202Br6 2 -anions being present in the solid. In the anions two square-pyramidal (y-octahedral) SeOHal4 groups are connected through a common Hal-Hal edge. The axial oxygen ligands (Se-O: 1.597(4) and 1.584(6) A) cause a pronounced stereochemical iraws-activation of the inert pairs at the Se atoms. As(C6H5)4So()Br3 is isotypic with P(C6H5)4SeOCl3.

	Title	Darstellung und Kristallstruktur des 2:3-Adduktes von Antimontrichlorid und 4-Phenylpyridin, 2 SbCl3 * 3 (CnH9N) Preparation and Crystal Structure of the 2:3 Adduct of Antimony Trichloride and 4-Phenylpyridine, 2SbCl3 * 3(CnH9N)
	Abstract	A congruently melting phase of molar ratio 2:3 was identified in the system SbCl3/4-phenylpyridine. The structure consists of two different types of complex units: One SbCl3 molecule is bonded to one 4-phenylpyridine ligand only, whereas the other one forms a complex with two 4-phenylpyridine ligands. The SbCl3 unit in the 1:1 species is pyrami-dally shaped, whereas the SbCl3 unit in the 1:2 species displays a T-shaped geometry. The mean angle between the phenyl and pyridyl planes is 33.3°; mean bond lengths are <Sb-Cl> = 247.6 pm and <Sb-N> = 241.7 pm.

	Title	Crystal Structure of Lead Sulfite
	Abstract	The crystal structure of orthorhombic PbSOß (Pnma, Z = 4, a = 790.3(1), b = 548.8(1), c = 680.2(1) pm) has been determined using single crystal X-ray diffraction data (final R for 663 reflections with I > 2<r(I) = 0.052). The para-meters of the atoms in the asymmetric unit are: Pb(4c) 0.. The sulfite ion has S-O distances of 149.4(7) and 153.7(5) (twice) pm. The Pb-0 distances of the edge-connected Pb-0 7 polyhedra (distorted mono-capped trigonal prism) range from 253.4(5) to 284.8(5) pm. The structure is closely related to that of PbS04.

	Title	Untersuchungen an Polypseudohalogeniden, II [1] Darstellung und Kristallstruktur des Rubidiumdicyanotriiodids, Rb[I(ICN)2] Preparation and Crystal Structure of Rb[I(ICN)2]
	Abstract	The new compound Rb[I(ICN)2] can be prepared in aqueous solution by simple addition of two mole equivalents of ICN to one formula unit Rbl. The solid is isotypic with CS[I(ICN)2] and crystallizes in the orthorhombic space group Pmmn with a = 16.246 A, b = 6.795 A, c = 4.397 A and Z = 2. The crystal structure has been solved from diffracto-meter data and refined to R = 0.035 for 313 observed reflections. The structure may be interpreted as a layer-like package of Rb+ cations and pentahalide-analogous anions [I(ICN2]~. The anionic groups are angular with symmetry mm 2 and y(I-I--I) = 128.69°, 0>(I--I-C) = 175.5°, <p(I-C-N) = 177°, d(I~-I) = 3.271 A, d(I-C) = 2.11 A, d(C-N) = 1.13 A. The cation is surrounded by a distorted cube of iodine atoms with a minimum distance d(Rb-I) = 3.775 Ä. Some additional results on the reactions of alkali halides and halogenocyans in different solvents are mentioned and compared with those described elsewhere.

	Title	Synthese und Struktur von N2S3C1 + SbCI^ Synthesis and Structure of N2S3C1+ SbCl6~
	Abstract	N2S3C1+ SbClö -was prepared by chlorination of N4S4 • SbCls with elemental chlorine. The crystals are monoclinic, P2i/c, with a = 1492.4(4), b = 1233.6(2), c = 1437.5(4) pm, ß = 91.40(2)°, and R = 0.059 for 3663 observed reflections. There are two independent cations and anions in the asymmetric symmetric unit. The appreciable interionic inter-action results in a high density of q = 2.642 g • cm -3 (calcd). In einer vorausgegangenen Arbeit berichteten wir u.a. über Reaktionen des Chlortrithiadiazylchlorids 1 mit Lewis-Säuren [1], Bei diesen Reaktionen wird im allgemeinen nur das ionogen gebundene Cl sub-stituiert, so daß sich Verbindungen der Formel N2S3C1+ MCI4-(M = AI, Fe) ergeben. Lediglich SbCls reagiert mit 1 unter Substitution beider Cl zu N2S3(SbCle)2. Die Bildung der monosubstituierten Verbindung N2S3C1+ SbCls -2 wurde nicht beob-achtet. Nun gelang uns die Darstellung von 2 durch Chlorierung des Addukts N4S4 • SbCls [2] mit ele-mentarem Chlor. Experimenteller Teil

	Abstract	The crystal structures of the anhydrous cadmium sulfites CdS0 3 -I (¥2 x /c, Z=4), CdS0 3 -II (P2/C, Z=8), and CdS0 3 -III (R3, Z=18 for the hexagonal cell) have been determined by means of single crystal X-ray diffraction data. The final R for the 1475, 2349, and 2138 observed reflections are 0.040, 0.034, and 0.073. Coordination of Cd is trigonal-prismatic, a hitherto unknown coordination of Cd in salts of oxoacids, in CdS0 3 -I and CdS0 3 -II, and octahedral in CdS0 3 -III. The Cd0 6 -polyhedra are arranged in two-dimensional (CdS0 3 -I) and three-dimensional (CdS0 3 -II and CdS0 3 -III) networks. S0 3 2-groups act as monodentate and in CdS0 3 -I and CdS0 3 -II also as bidentate ligands. Cd—O distances range from 224.5(3) to 244.6(3) pm, with an average of 231.5 pm for the trigonal-prismatic and of 231.0 pm for the octahedral coordination. S—O dis-tances range from 152.3(3) to 155.3(3) pm with an average of 153.7 pm, the O —S—O angles from 99.2(2) to 106.7(3)° with an average of 103.2°.

[Cs(18-crown-6)]2[Hg2(Se4)3] has been prepared by the reaction o f a lithium polyselenide solution in D M F with H g(C H 3COO)2 in the presence o f CsBr and 18-crown-6. Both com pounds are obtained as dark red crystals and characterized by X-ray structure determinations. (PPh4) 2[H g(Se4) 2]: Space group P 2,/c, Z = 4, 3021 observed unique reflexions, R = 0.082. Lattice dim ensions at 20 °C: a = 1046.0(3), b = 2129.4(2), c = 2213.1(3) pm,/? = 97.62(2)°. The com pound consists o f PPh4+ ions and anions [Hg(Se4)2]2", in which the mercury atom is a spi-rocenter o f puckered HgSe4 rings. [ Cs(18-crown-6) J2[H g2(Se4)3J: Space group la, Z = 4, 2859 observed unique reflexions, R = 0.074. Lattice dimensions at 20 °C: a = 2018(1), b = 1097.0(2), c = 2317.1(5) pm, ß = 99.40(3)°. The compound forms an ion triple which originates from Cs-Se contacts o f 382 to 390 pm with the [Hg2(Se4)3]2~ ion. The latter can be described as a [FlgtSe^JJ2-ion, which has contacts with a HgSe4 fragment.
