 Title    Neue 13 2 06 3 7-Verbindungen New 13 2 06 3 7 Compounds  
 Abstract    New quaternary compounds AgIn2X3Y (X = Se, Te; Y = Br, I) could be synthesized from AgY-In2X3-mixtures at atmospheric pressure. The crystal structures are defect-wurtzite (AgIn2S3Br) or defect-zinc-blende (AgIn2Te3Br, AgIn2Te3I). A transformation to high-pressure phases with spinel structure (AgIn2Se3Br, AgIn2Se3I) or defect-NaCl-structure (AgIn2Te3Br, AgIn2Te3I) takes place at 20 and 40 kbar. respectively. AgIn2S3I with spinel structure could by synthesized from Agl and In2S3 at 40 kbar, 500 °C.

 Title    Spectroscopic Evidence for Pseudorotation of Seven-Membered Chalcogen Rings in Solution [1]  
 Abstract    The 77 Se NMR spectrum of l,2-Se2S5 exhibits one singlet at 1077.3 ppm indicating pseudorotation in solution; the same conclusion is reached from the solution Raman spectrum of S7 showing characteris-tic line broadening compared to the solid state spec-trum.

 Abstract    The potassium selenostannate(IV) K4Sn3Ses has been prepared by methanolothermal reaction of K2C03 with elemental Sn and Se at 190 °C and its structure established by X-ray structural analysis. The unit cell contains isolated [Sn3Se8] 4-anions consisting of a central SnSe4-tetrahedron edge-bridged to two further tetrahedra. Crystallographic D2-symmetry is observed for these an-ions. The four-membered rings are markedly distorted with Sn —Se bond distances of 2.520(1) to the central tin atom as compared to long Sn-Se distances of 2.622(1) Ä to the tin atoms of the outer tetrahedra. The terminal Sn —Se bonds have a length of 2.473(1) Ä.

 Title    Darstellung und Kristallstruktur von Zinkazid * 4-Methylpyridin Preparation and Crystal Structure of Zinc Azide * 4-Methylpyridine  
 Abstract    Zinc azide • 4-methylpyridine (1) is formed by the reaction of zinc azide with the corresponding pyridine in aqueous solution. The crystal structure was determined by single crystal X-ray diffrac-tion methods. The crystals of 1 are monoclinic, space group C2/c, Z = 4, a = 1085.5(2), b = 1692.7(11), c = 619.7(6) pm, ß = 113.47(5)°. Each zinc atom is surrounded by five nitrogen atoms (four from azide groups and one from the pyridine adduct) in a distorted trigonal bipyramidal fashion. The ZnN5-polyhedra share common edges to form chains along the crystallographic c-axis.

 Abstract    The methylthio-chlorophosphanes RP(Cl)SMe [R = Me (1). Et (2). Ph (3)] are prepared in good yields (62—65%) by condensation reactions of the corresponding dichlorophosphanes RPC12 with methanethiol in the presence of trimethylamine (molar ratio 1:1:1). 1 and 3 have been used to produce 3-phospholene sulfides in a one-pot process by reaction with 1,3-dienes at 70 to 100 °C. Reaction proceeds via [1 +4]-cycloadducts, which in suitable cases can be isolated and used for the preparation of the corresponding 3-phospholene oxides. New compounds were characterized by elemental analysis and spectroscopic investigations (NMR. MS).

 Title    Koordination des dreizähnigen makrocyclischen Liganden l-Thia-4,7-diazacyc!ononan an Palladium(II) und Platin(II) Coordination of the Tridentate Macrocyclic Ligand l-Thia-4,7-diazacyclononane to Palladium(II) and Platinum(II)  
 Abstract    The reaction of PdAc-> and K2PtCl4 with the ligand l-thia-4,7-diazacyclononan (Cf,Hi4N2S — L) yield crystals of [PdL2](PF6)2 (4) and [PtL2]Br2-H20 (5), respectively. The structures of 4 and 5 have been determined. Crystal data: 4, monoclinic, space group P2,/c, a = 719.2(1), b = 1712.5(3), c = 936.8(2) pm. ß = 99.15°, Z = 2; 1708 reflections, R = 0.029. 5, monoclinic, space group C2Jc, a = 1682(2). b = 786(1), c = 1573(1) pm. ß = 108.1(1)°, Z — 4; 1706 reflections, R — 0.070. 4 contains octahedrally coordinated Pd(II); in addition to the square planar PdN4 group (mean Pd —N bond length 206 pm) the S-donor atoms are weakly coordinated in the axial positions (Pd—S: 303.4(1) pm). In 5, however, Pt(II) is in a square planar ligand environment. The S-donor atoms are bent away from the axial positions of the central atom.

Et, /-Pr. /-Bu, c-Hex. (-)Menthyl. Ph) and RPBr2W(CO)5 (R = (-)Menthyl, Ph) are obtained from M(CO)5THF and organodi-bromophosphane. Dehalogenation of the chromium complexes with magnesium in THF leads to (RP)3[Cr(CO)5]m (m = 1. 2, 3) with m depending on the bulkiness of R. When dissolved in THF the binuclear complexes (m — 2) are gradually converted into mononuclear compounds. The isomeric structure of the cyclotriphosphane complexes is deduced from their 31 P{'H} NMR spectra.

 Title    The Thermal Decomposition of Ammonium Metavanadate(V) in Open and Closed Systems  
 Abstract    The thermal decomposition of ammonium metavanadate(V) has been studied at atmospheric pressure, at hydrothermal, and high-pressure conditions, respectively. In a closed high-pressure system a redox reaction between vanadium(V) and ammonia takes place, to yield with increasing temperature the compounds (NH 4) 2 V 6 0 12 (0H) 2 , VO : _ A (OH) A , and V 2 "0 2 "_,, the composition of the product eventually approaching V 2 0 3 at 1100 °C. All these compounds can easily be con-verted into V 2 O s by heating in air. The mid-infrared spectra of the decomposition products obtained by slow heating of NH 4 VO, in air, are virtually identical and show that ammonium hexavanadate(V), (NH 4) 2 V h O| 6 , is the most important, and perhaps only, intermediate in the "non-reduction" case. On further heating, (NH 4) 2 V 6 0 lft may not only loose ammonia and water to form V 2 0 5 but could as well partially be reduced by ammonia. This could explain the diversity of intermediate "compounds" described in the literature. Hydrothermal reaction of NH 4 VO, yielded (NH 4) 05 V 2 O 5 , (NH 4) 2 V,0 8 , and V 2 0 3 at rather low temperatures.

 Title    Studies on Organomercury(II) Complexes of Isoniacinamide  
 Abstract    Organomercury(II) complexes involving isoniacinamide(I) of the type. RHgCl(L)(II) [R = phenyl, o-, p-hydroxyphenyl (op-HOQH 4), p-acetoxyphenyl (p-AcOC ft H 4), 2-furyl (2-CJLO): L = isoniacinamide] have been synthesized and characterized. Conductance measurements indicate that the complexes are non-electrolytes. From IR and UV spectral studies it is concluded that isoniacinamide is coordinated to the mercury(II) ion through the ring nitrogen atom. 'H and l? C NMR support the stoichiometry of the complexes. Fluorescence studies have been made for o-, p-HOC 6 H 4 HgCl(L) complexes. For C 6 H 5 HgCl(L), p-HOQH 4 HgCl(L) and p-AcOC 6 H 4 HgCl(L) complexes, thermal studies (TG and DSC) have been carried out and relevant kinetic and thermodynamic parameters for thermal degradation have been enumerated. The fragmentation pattern of the complexes has been analysed on the basis of mass spectra. The C 6 H 5 HgCl(L) and /?-AcOC 6 H 4 HgCl(L) complexes have been screened for antibacterial activity.

 Abstract    , (NC) 4 Pt(CNH) 2 , (NC) 2 M(CNH) 4 (M = Fe, Ru, Os) undCo[bis(dimethyIglyoximato)](CN)CNHmit Epoxiden: 2-Hydroxyalkylisocyanid-und Oxazolidin-2-yIiden-MetalIkomplexe Pseudohalogeno Metal Compounds, LXVIII [1] Reaction of Cyano Metal Acids NCAuCNH, (NC) 4 Pt(CNH) 2 , (NC) 2 M(CNH) 4 (M = Fe, Ru, Os) and Co[bis(dimethylglyoximato)](CN)CNH with Epoxides: 2-Hydroxyalkylisocyanide and Oxazolidine-2-ylidene Metal Complexes NCAuCNH reacts with expoxides to give oxazolidine-2-ylidene (2) and 2-hydroxyalkyl com-plexes (3), respectively. Complexes with cyclic carbene ligands (NC) 4 Pt(-C-O —C—C-NH) 2 (5) and (NC)(Hdmg) 2 Co-C-O-C-C-NH (7) are formed from the corresponding isocyanic metal compounds and oxiranes. 5b has been characterized by crystal structure determination. Ring opening of phenyloxirane occurs at the phenyl substituted carbon atom. (NC) 2 M(CNH) 4 (M = Fe, Ru, Os) and oxirane yield mixtures of (NC) 2 M(—CN—C—C—OH) 4 and (NC) 2 M[—CN—C—C—(—O—C—C—)"—O—C—C—OH] 4 .

 Title    fraws-4-Phenyl-3-buten-2-one from the African Harvester Ant Messor galla (Mayr) (Hymenoptera: Formicidae)  
 Abstract    Messor galla, Pheromone, rra«.s-4-Phenyl-3-buten-2-one. Dufour's Gland By gas chromatography mass spectrometry and synthesis of authentic standard, rrarts-4-phenyl-3-buten-2-one for the first time as well as known hydrocarbons have been identified in the Dufour's gland secretion of the African harvester ant Messor galla (Mayr).
