 Abstract    Reaction o f [(cod)IrI] 2 (cod = 1.5-cyclooctadiene) with m ethyllithium in the presence of diphenylacetylene (tolane) yields a (cod)Ir com plex (3) with a l-benzyl-2 .3 -diphenyl-7 -methyl-indenyl ligand which is formed by a novel cyclization o f two tolane units with participation o f a m ethyl group. The com pound was characterized by spectroscopic m ethods and by X-ray diffrac­ tion analysis.

Instead, an isom er o f the expected com ­ pound, with two N.N '-dim ethylurea bridges across a A5P —O —A5P bond system was obtained. The identity o f the product was established by spectroscopic means (IR , N M R . mass spectroscopy), and by a single crystal X-ray diffraction study.

 Abstract    A series of magnesium inner complexes has been prepared by reacting M gH2 (prepared by homogeneous catalysis) with dialkylallyl-and -3-butenylam ines and -3-butenylethers in the p re­ sence of catalytic amounts of Z rC l4. The m onom eric nature of bis(4-m ethoxybutyl)m agnesium has been confirmed by X-ray diffraction. The analogous syntheses of bis(3-alkoxypropyl)magnesium com pounds failed: cleavage of the allyl ether with elimination of propene occurred. This cleavage reaction is accelerated by catalytic amounts of NiCl2 or ZrC l4.

 Abstract    The reaction o f bis(dialkylam inoalkyl)-and bis(4-alkoxybutyl)m agnesium inner com plexes with M gEt2 leads to the form ation of ethyl(dialkylam inoalkyl)-and ethyl(4-alkoxybutyl)m agnesium com pounds. The X -ray crystal structures o f ethyl(3-N ,N -dim ethylam inopropyl)m agnesium and ethyl(3-N -cyclohexyl-3-N -m ethylam inopropyl)m agnesium confirm that the com pounds are dim eric with the a-C -atom o f the chelating ligand bridging the magnesium atoms. The difference in reactivity of the M g —Et and M g—C"H2nX bonds (X = NR 'R ", O R) makes itself apparent in the reaction of these com plexes with ethylene: up to six ethylene m olecules are inserted, whereby in the case of the ethyl(4-alkoxybutyl)m agnesium com pounds insertion occurs preferentially into the M g—Et bond w hereas in the case o f the ethyl(dialkylam inoalkyl)m agne-sium com pounds both bonds are equally reactive.

 Title    Darstellung und Kristallstruktur von TI3AgTe2 Preparation and Crystal Structure of Tl3A gTe2  
 Abstract    The new compound Tl3A gTe2 was prepared by the reaction of Tl5T e3, Ag and Te at 550 °C, followed by slow cooling of the melt. It forms black crystals of metallic lustre which decompose by the influence of humidity. Tl3A gTe2 is monoclinic, space group P2,/c, with a = 11.020(5), b = 7.427(2), c = 9.888(3) Ä , ß — 116.62(4)°, Z = 4. The crystal structure was determ ined from four-circle diffractom eter data and refined to a conventional R of 0.083 for 1015 observed reflec­ tions. Tl3AgTe2 crystallizes with a new structure type, characterized by infinite layers, 2[A gT e2], running along (100), which are separated from each oth er by thallium atom s. The layers are built up by pairs of edge sharing A gTe4-tetrahedra linked together by common Te atoms according to |[A g (T e)T e 3/3]. The crystal structure is based on an arrangem ent of distorted c.p. tellurium layers, stacked along [010] (stacking sequence h2). All octahedral voids are occupied by Tl-atoms, Ag-and Tl-atoms are regularly distributed over the tetrahedral sites.

 Abstract    The hydrogen bonding in several acid salts o f 4,5-dichlorophthalic, 3,6-dichlorophthalic and 3-fluorophthalic acid have been studied by IR spectroscopy and X-ray structure analysis. N H 4H [3,6-C12C8H 204] and KH[3-FCgH 30 4], with 0 ---0 distances o f 247 and 254.1(4) pm, respectively, belong to Speakm an's type B2 of acid salts o f dicarboxylic acids. In N H 4H[4,5-C12C8H 20 4] • H 20 a short hydrogen bond o f 253(1) pm is form ed to the H 20 m olecule. A very short intramolecular hydrogen bond o f only 234.0(10) pm length was found in N (C 4H 9)4H[4,5-C12C8H 20 4], In the [3,6-Cl2C8H 20 4]2_ dianion both carboxylate groups are nearly orthogonal to the phenyl ring.

 Abstract    By reaction o f trithiazylchloride, (NSC1)3, with PPh4[RuCl4(N O)]2 in dichlorom ethane the thiazylchloridenitrosyl com plex PPh4[RuCl4(N O)(N SC l)] is obtained; its vacuum pyrolysis at 2 0 0 -2 2 0 °C yields the thionitrosyl com plex (PPh4)2[RuCl4(N S)]2 which crystallizes from C H 2C12 solution with four m olecules o f CH 2C12. Both com pounds were charaterized by their IR spectra and by X-ray crystal structure determ inations. Crystal data: PPh4[RuCl4(N O)(N S C l)], m on o­ clinic, space group P 2 xln, Z = 4, a = 982.6, b = 1700.0, c = 1772.3 pm , ß = 104.79° (2548 observed reflexions, R = 0.046); (PPh4)2[RuCl4(N S)]2-4 C H 2C12, triclinic, P I , Z = 1, a = 952.9, b = 1380.0, c — 1458.5 pm , a — 112.91, ß = 106.67, y = 92.61° (3760 observed reflexions, R = 0.053). In the [RuCl4(N O)(N S C l)]e ion the nitrosyl and thiazyl chloride ligands occupy e x ­ positions; bond lengths indicate double bonds in the linear Ru = N -0 group, while the NSC1 m olecule is attached by a donor-acceptor interaction R u -N = S -C l , although with a rather short Ru —N bond o f 198 pm (N = S 144 pm, S —Cl 213 pm). The centrosymm etric [RuC14(N S)]220 ions have chloro bridges and NS ligands in axial positions; the nearly linear R u = N = S group has bond lengths R u = N 175 pm and N = S 147 pm.

 Title    Preparation and Crystal Structure of £7s-Tetrachlorobis(cycIooctasulfurmonoxide)tin(IV) [1]  
 Abstract    Yellow crystals of c/s-[SnCl4(S8 0) 2] containing the homocyclic sulfur oxide S80 have been prepared from the com ponents in carbon disulfide at —35 °C. A n X-ray structural analysis carried out at —105 °C showed the com pound to be monoclinic, space group P2 Jn with Z = 4 in a unit cell of dimensions a = 821.2(2) pm, b = 1331.9(4) pm , c = 2071.7(6) pm and ß -91.82(2)°. The structure was refined to a final agreem ent factor R = 0.038 for 2022 reflections. The tin atom is surrounded by a distorted octahedron of two oxygen atom s in cw-positions and four chlorine atom s in accordance with other oxygen-bonded complexes of SnCl4. The molecular symmetry is approximately C2, and the SS bond lengths in the ligands vary betw een 201 and 218 pm. V ibra­ tional spectra of [SnCl4 (SH 0) 2] are reported. The title com pound is the second example containing S80 as a ligand.

 Title    Über Erdalkalimetallverbindungen des l,l-Dicyanoethylen-2,2-dithiolats, III+ Die Kristallstruktur von SrS2C4N2 * 5 H20  
 Abstract    By reaction of CS2 with m aleonitrile in presence of sodium ethanolate in ethanol, N a2S2C4N 2 is obtained. SrS2C4N2-5 H 20 was synthesized by reaction of Sr(NCS) 2 with N a2S2C4N2 in ethanol. It crystallizes monoclinically, space group P2!/c, with a = 9.201(2), b — 9.990(6), c = 14.605(5) Ä,/3 = 122.3(3)°, Z = 4. The com pound is isotypical with CaS2C4N2-5 H 20 . A structural model based on equivalent metal positions was refined to R -0.057. The crystal structure contains layers of nearly planar [S2C = C (C N)2]2' anions held together by interspersed Sr2+ cations in a tricapped trigonal prismatic surrounding of 6 0 and 3N atoms. The S atom s of the ligand are not included in the coordination sphere of Sr2+ but are involved in several O — H -S hydrogen bonds.
