| Bor-und Arsen-methoxotetrafluorotellurate(VI)  | | | Abstract
| Synthesis, Boron and Arsenic Methoxotetrafluorotellurates(VI), NMR Spectra The interaction of eis-and tfrans-HOTeRiOCHs with BG3 yields B(cis-and trans-0TeF40CH3)3. The ability of these compounds to transfer the CH30TeF40 entities has been demonstrated in reactions with ÄSF3, with the formation of As (eis-and trans-0TeF40CH3)3 respectively. All compounds have been characterized by NMR spectroscopy (125Te, 19F> 11B, iH). | | |

| The crystal structures ofCH3S-CO-CONH2 (1), CH3S-CS-CONH2 (2), C2H50-C0-CSNH2 (3) and K[OSC-CONH2] (4) have been determined by single crystal X-ray diffraction. The molecules 1, 2 and 3 are nearly planar and form centrosymmetric dimers by N H • • • O or N-H--S hydrogen bonds with the amidic oxygen or sulfur atom as acceptor atoms. The anion of 4 is not quite planar. The torsional angle around the C-C bond is 18.4°. The con-formations of the title compounds are E, Z' (1 and 2), Z, Z' (3) and Z (4). According to the vibrational spectra, which are discussed briefly, 1 and 3 retain their conformation also in solution. | | |

| The six membered ring of composition (CH3)2NCN3S2Cl2 8 a was prepared from N,N-dimethylguanidinhydrochloride and trithiadiazindichloride. 3 a was characterized on the basis of mass, 1 H, 13 C NMR spectra and X-ray structure analysis. Crystals of 3 a are monoclinic, space group P2i/c, with a — 660.3(6), b = 834.5(7), c = 1774.7(15) pm, ß = 112.83(6)° and Z = 4. The C2N unit lies approximately in the plane of the [-CNSNSN-] ring, with both Cl atoms on the same side of the ring. | | |

| Deprotonated Complexes of Bis(o-aminobenzenesulfonyl)ethylenediamine with Mn(II), Co(II), Ni(II) and Cu(II)  | | | Abstract
| The new complexes K2[ML2] (M = Mn, Cu), K2[ML2(H20)2] (M = Co, Ni), K2[Cu2L2(OH)2] and K2[Cu2L2(0H)2(H20)4], where LH2 = Bis(o-aminobenzenesulfonyl)ethylenediamine, have been prepared. Properties, X-ray powder patterns, molar conductance measurements, magnetic moments and spectral (IR, diffuse reflectance, visible in solution) data are discussed in terms of possible structural types and the nature of the bonding. Distorted octahedral geometries are proposed for the Mn(II), Co(II), Ni(II) and dimeric Cu(II) chelates in the solid state, while K2[CuL2] appears to have a distorted tetrahedral structure. The Mn(II) complex exhibits evidence of a polymeric configuration. The L 2 ~ anion acts as a bidentate N2 or tetradentate N4 ligand. | | |

| Spectroscopic Studies, Crystal Structure, (Pyrazolinonyl)-(hydroxypyrazolylium)methane Cations The structures of la-Id were investigated by spectroscopic methods and in the case of la in addition by X-ray diffraction, la, vicarious for the compounds 1, is stabilized in solution and in the crystal by an intramolecular hydrogen bond in an eight-membered ring. The IR and NMR spectra show that 1 exhibit a symmetrical structure. In the case of 1 a the molecular structure is affected by unsymmetrical packing and electrostatic effects in the crystal and is therefore approximated best between the forms I and II. | | |

We describe the preparation of 4,8-dimethoxy-bis[l,3]dioxolo[4,5]benzo[l,2-d; l',2'-f][l,3]-dioxepine (3). It shows a high Sß-reactivity. Bromination yields the monobromo-and dibromocompounds 3 a and 3 b. Treatment of 3 with copper(II) nitrate leads to the dinitro-compound 3c. With the same reagent 3a gives 3d. Reduction of 3d with hydrogen and Palladium as catalyst yields the mono-amine 3e under bromine loss. Under the same reduction conditions in acetic anhydride 3d and 3c yields 3f respectively 3g. The carboxylic acid 3i and the aldehyd 3h are prepared by bromine-lithium exchange from 3 a. In the same manner the dibromocompound 3 b is a suitable starting material to obtain the dicarboxylic acid 3k and the dialdehyd 3j. 3j undergoes easily a thiazolium catalysed oin-condensation, yielding the phenanthrenequinone 31. The cyclic anhydride 3 m can be prepared by heating 3 k in acetic anhydride. | | |

After quenching with tri-methyltin chloride essentially two stannyl derivatives of 1 were obtained. The stannyl group did not bind to the allylic carbon of 1 as expected but to C-6 and C-7. This has been shown by means of elemental analysis, mass spectroscopy as well as iH, 13 C and U9 Sn NMR spectroscopy. | | |

| Über neue Cyano-nitrosylmanganate und Isonitril-nitrosyl-Komplexe des Mangans On New Cyano Nitrosyl Manganates and Isonitrile Nitrosyl Complexes of Manganese  | | | Abstract
| The anionic cyano nitrosyl manganates [Mn(NO)(CO)3CN] _ and [Mn(NO)3CN]~ are formed by the reactions of Mn(NO)(CO)4 andMn(NO)3CO with NaN(SiMe3)2. The alkyla-tion of these anions with [R30]BF4 (R = Me, Et) leads to the corresponding isonitrile complexes Mn(NO)(CO)3CNR and Mn(NO)3CNR. IR, mass and 13 C NMR spectra indicate trigonal-bipyramidal coordination for nitrosyl tricarbonyl derivatives, with three CO ligands in facial positions and NO in the equatorial plane. Based on the temperature de-pendent 13 C NMR spectra of Mn(NO)(CO)3CNR and Mn(NO)(CO)4 the fluctional behaviour of these compounds could be demonstrated with /1G+ values of 48 kJ/mol or less for the CO exchange. | | |

| Tetrathiophosphate, X-Ray The structure of the title compound has been determined by X-ray crystallography. The title compound is synthesized from the elements at 600 °C. Its crystal structure, derived from powder data [3] is refined by single crystal diffractometer data. The structure is trigonal (P"3ml, o, = 684.1(1), c = 724.4(1) pm); Pd 2+ cations and PS4 3 -anions form a network with an anti-Claudetite (AS2O3) type structure. The PS4 units are distinctly distorted from ideal tetrahedral symmetry. The Pd atoms have a planar environment of 4 S atoms. | | |
