 Title    Übergangsmetallkomplexe mit Schwefelliganden, XVIII* Synthese und  
 Abstract    Reaktionen von [Ru(L)(PPh3)dttd]-Komplexen mit kleinen Stickstoffverbindungen L = NH3, N2H4, N2H3CH3, N2H3C6H5 sowie NO+ (dttd2-= 2,3;8,9-Dibenzo-l,4,7,10-tetrathiadecan (—2)) Transition Metal Complexes with Sulfur Ligands, XVIII* Synthesis and Reactions of [R u(L)(PPh3)dttd] Complexes with Small Nitrogen Com pounds L = N H 3, N2H 4, N2H 3C H 3, N2H 3C6H 5 and N O + (dttd2-= 2,3;8,9-D ibenzo-l,4,7,10-tetrathiadecane (—2)) D ieter Sellmann+ Ruthenium Sulfur C om plexes, N itrogen Ligands The com plex fragment [Ru(PPh3)dttd], (dttd2-= 2,3;8,9-dibenzo-l,4,7,10-tetrath iad ecane (— 2)), coordinates small nitrogen com pounds, which have only o-as well as a-jr-donor proper­ ties. The reactions o f [Ru(PPh3)2dttd] with L — N H 3, N 2H 4, N 2H 3C H 3 and N 2H 3C6H 5, respec­ tively, give the corresponding [R u(L)(PP h3)dttd] com plexes. O xidation o f the hydrazine com ­ plex [R u(N 2H 4)(PPh3)dttd] yields [a-N 2H 2{R u(PP h3)dttd }2], the first diazene com plex in which the unstable N 2H 2 is bound to a sulfur coordinated m etal center and stabilized by a 4 c —6 e Ru— N — N — Ru system , steric shielding as well as thiolate — S---H (n,h2)---N hydrogen bridges. The reactions of the ammonia and the hydrazine com plexes, respectively, with N O PF6 yield the nitrosyl com plex [R u (N O)(PP h3)dttd]PF6 as final product; in the case o f [R u(N 2H 4)(P P h3)dttd] the intermediate formation of an azido com plex is observed IR -spectroscopically.

The vibrational spectra o f the m ixed ligand com plexes are assigned according to point groups D 4h, C4v, C3v and C2v. The increased bond strength com pared with the corresponding O s(IV) com plexes is indicated by a significant shift to higher energy by about 5 -1 5 % . The O s -C l stretching vibration o f [OsF5C1]~ and also the symmetric ClO sCl o f fra«5-[OsF4Cl2]~ is split by the isotopes 35C1 and 37C1, showing two and three well resolved sharp Ram an lines in the expected ratio o f intensities, respectively.

 Title    Interpretation of Substituent Angular Parameters of Monosubstituted Benzenes by Means of ab initio STO-3G Fully Optimized Molecular Structures and Charges Densities Part VI of the Series: "Crystallographic Studies and Physicochemical Properties of ^-Electron Systems" [1]  
 Abstract    jr-Electron System s, M onosubstituted B enzen es, Substituent Angular Parameters The angular variations o f m olecular structures calculated for 17 m onosubstituted derivatives of benzene by use o f ab initio analytical gradient optim ization at the ST O -3G level have been correlated by multiple linear regression analysis with M ulliken o-and jr-electron charge densities at corresponding ring carbon atoms. Variations o f angles y at m eta positions are solely due to jr-electron effects (R = 0.961). Changes in angles ß at ortho positions are independent o f o-or jr-electron effects but may be related to steric effects (R = 0.719) alone or additionally to charge densities on ortho protons (for dual regression R = 0.846). A n gles a at ipso atom s depend significantly on both, o-and jr-electron charge densities in the ratio o f 70% to 21% with R = 0.974 for dual regression. Variations o f angles d at /w a -p o s itio n s depend on all three effects considered (with correlation coefficient for a triple regression R = 0.951) in the ratio 37.6% :2 8 .3 % : 34.1% for steric effects, o-and jr-electron charge densities, respectively.

 Abstract    Phenyl Thioxophosphane, o-Q uinones, [4+ l]-C ycloaddition, 1,3,2-Benzodioxaphosphol-2-sulfides Phenyl thioxophosphane (1) — generated by therm al cycloreversion from 7 along with the dihydropyridazine 8 — is trapped by [4+1] cycloaddition with the o-quinones 9 a —f by form ation of the dioxaphospholsulfides 10a—f. Solvolysis of 10a—c, e and f with m ethanol yields the phenol derivatives 12a—e (in the case of 10b the isomer 12b' is form ed, too). This reaction is reversible (12a—c—»10a—c) and accompanied by form ation of the isomers 13a—c. The phenanthrene quinone m ethanide 14 is also suitable for the trapping reaction of 1 (—»15—>17).

 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.

 Title    YCoC and Isotypic Carbides with a New, Very Simple Structure Type  
 Abstract    Crystal Structure, Equiatomic Ternary Rare E arth Metal C obalt Carbides The crystal structure of the new com pound Y CoC was determ ined from X-ray powder data. It is tetragonal, space group P4:/mmc. with a = 0.36500(4) nm, c = 0.68636(9) nm and Z = 2 formula units per cell. The residual for a refinem ent of D ebye-Scherrer data is R = 0.048 for 22 structure factors and 3 variable param eters. The structure is of a new type with no variable positional param eter. The arrangem ent of the metal atoms corresponds to that of the CsCl structure. The tetragonal superstructure with a doubled c axis arises through the ordered insertion of carbon atoms on octahedral sites formed by four Y and two Co atoms. The hydrolysis of YCoC in hydrochloric acid yields mainly m ethane, propane, and ethane. The compounds LnCoC (Ln = Gd —Tm. Lu) are isotypic with YCoC.

 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.
