 Title    Über Polygermane, XVIII [1] Drucksynthese der mehrfach funktionellen Digermane Ph 6 _"Ge 2 Cl" (n = 2, 3, 4) und von Ph 2 GeCl 2 On Polygermanes, XVIII [1] Synthesis of the Multifunctional Digermanes Ph 6 _"Ge 2 Cl" (n = 2, 3, 4) and of Ph 2 GeCl 2 under Pressure  
 Abstract    Reaction of Ph 6 Ge 2 with liquid HCl under pressure leads to di-, tri-and tetrachloro phenyl-digermanes. The yield of higher chlorinated products increases with increasing pressure. The analogous reaction of Ph 4 Ge yields Ph 2 GeCl 2 quantitatively. The Ge-Ge bond is most unstable in the case of Ph 3 Ge 2 Cl 3 both chemically and thermally. The crystal structure of Ph 2 Ge 2 Cl 4 has been determined (R = 0.057), Ge-Ge 241.3(1) pm.

 Title    Übergangsmetall-Komplexe mit Schwefelliganden, XXVII* Synthese und Reaktivität der Nitrosyl-und Nitrido-Ruthenium-Komplexe mit 1,2-Benzoldithiolat-Liganden [Ru(NO)(S 2 C 6 H 4 ) 2 r bzw. [Ru(N)(S 2 C 6 H 4 ) 2 r Transition Metal Complexes with Sulfur Ligands, XXVII* Synthesis and Reactivity of the Nitrosyl-and Nitrido-Ruthenium Complexes with 1,2-Benzenedithiolate Ligands [Ru(NO)(S 2 C 6 H 4 ) 2 ]~ and [Ru(N)(S 2 C 6 H 4 ) 2 ]~, Respectively  
 Abstract    The reaction of [Ru(NO) 2 (PPh 3) 2 ], [RuCl(NO) 2 (PPh 3) 2 ]PF 6 or [RuCl 3 (NO)(PPh 3) 2 ] with 1,2-benzenedithiolate(—2), C 6 H 4 S 2 : ~, leads to the 16e"-complex [Ru(NO)(S 2 C 6 H 4) 2 ]~, which was isolated as the NBu 4 + salt (1). The square pyramidal anion in [NBu 4 ][Ru(NO)(S 2 C 6 H 4) 2 ] coordi-nates PMe 3 with rearrangement of the sulfur ligands to give the six-coordinate cis-[NBu 4 ][Ru(NO)(PMe 3)(S 2 C 6 H 4) 2 ] (3); the rearrangement of the C 6 H 4 S 2 2 "-ligands from trans to eis coordination is proved by 13 C NMR spectroscopy. [Ru(NO)(S 2 C 6 H 4) 2 ]~ is rapidly reduced even under mild conditions. Reaction of 1 with NaBH 4 in MeOH leads to the reduction of NO to a nitrido ligand and the concomitant oxidation of (formal) Ru(III) to Ru(VI) yielding [NBu 4 ][Ru(N)(S^C 6 H 4)->] (2). This compound is also formed when the nitrosyl complex is reacted with SiMe 3 N 3 . [Ru(NO) 2 (PPh 3) 2 ] and [RuCl(NO) 2 (PPh 3) 2 ]PF 6 are denitrosylatedby dttd 2 ~ (dttd 2 " = 2,3,8,9-dibenzo-l,4,7,lÖ-tetrathiadecane(—2)) to give [Ru(dttd)(PPh 3) 2 ],

 Title    Darstellung und Kristallstrukturen von (Ph4P)4Sb8I28 und (Ph4P)Sb3l 10 (Ph = C6H5) Synthesis and Crystal Structures of (Ph4P)4Sb8I28 and (Ph4P)Sb3 l 1 0 (Ph = C6H 5)  
 Abstract    The compounds (Ph4P)4Sb8l 28 (1) and (Ph4P)Sb,Iio (2) were prepared by the reaction of Sbl3 and Ph4PI in acetonitrile (molar ratios 2:1 and 3:1 respectively). The structures of 1 and 2 were determined from single crystal X-ray diffraction data. 1 crystallizes in the triclinic space group P I with a = 1321.7(5), b = 1346.7(5), c = 2201.8(8) pm, a = 104.18(2), ß = 99.92(2), y = 100.33(2)°; 2: monoclinic, C2/c, a = 2371.1(2), b = 745.0(1), c = 2495.1(2) pm, ß = 100.75(1)°. Whereas 1 exhibits isolated SbsI284' ions, the anions of 2 are built up of polymeric chains [Sb3I 10_]x. In both compounds the distorted Sbl6 octahedra are linked by common edges. The Sb—I distances are in the range between 277.4 and 354.8 pm (1) and between 277.4 and 342.4 pm (2). The observed structures do not only depend on stoichiometry. the nature of the counter cations, and the possibility of oligomerisation but also on the wide variety of the Sb—I bond strengths and the different bridges formed by iodine. The lone pair of Sb(III) seems to be predominantly 5s: .

 Title    Stickstoffverbindungen von Elementen der dritten Hauptgruppe mit intra-und intermolekularen Donor-Akzeptor-Bindungen, III [1]. Dynamische Phänomene und Lewis-Säure-Stärke Nitrogen Compounds of Elements of the Third Main Group with Intra-and Intermolecular Donor Acceptor Bonds, III [1]. Dynamic Phenomena and Lewis Acidity  
 Abstract    Compounds of the general formula f BuN(H)-SiMe 2 -N(r Bu)ElX 2 (El = B, X = Me (lm), F (If), Cl (lc); El = AI, X = Me (2m), Cl (2c), Br (2b); El -Ga, X -Me (3m), Cl (3c), Br (3b); El -In, X -Me (4m), Cl (4c), Br (4b); El -Tl, X -Me (5m)) and r BuN(D)-SiMe 2 -N(r Bu)ElMe 2 (El = Al (2d), Ga (3d), In (4d)) have been characterized by IR and temperature dependent ! H NMR techniques with respect to their structural changes in solution. A reversible, dynamic, intramolecular equilibrium between two enantiomeric four-membered rings has been established to be responsible for the changes in the spectra. The cyclic form Bl, which arises from Lewis acid base interaction of the rerr-butyl-amino with the E1X 2 group, transforms to the mirror-image B2 via an acyclic intermediate, in which reorien-tation of the groups by rotation or inversion can take place. In the boron derivatives (lm, lc, and If) no comparable N—B interaction can be detected. The Lewis acidity of the E1X 2 group deduced from NH wave numbers increases within the following series: TlMe 2 <GaMe 2 ~InMe 2 <AlMe 2 <GaBr 2 =InBr 2 <GaCl 2 ~AlBr 2 ~InCl 2 <AlCl 2 . Intramolecular hydrogen transfer from one nitrogen atom to the other can be excluded by comparison of the rate constant k H vs. k D . The free enthalpy of activation A G* depends on the acidity of E1X 2 , the steric requirements and the relative masses of X. The syntheses and characterisation of If, 2b, 3b, 4b, 2d, 3d, and 4d are described.

 Title    das erste Chalcogenid mit zweiwertigem Aluminium Al 7 Te 10 — the First Chalcogenide of Divalent Aluminum  
 Abstract    Al 7 Te 10 is prepared from a melt of the elements in stoichiometric amounts in a corundum crucible contained in a sealed quartz ampoule. The ruby red cube shaped crystals are stable below 840 K. The structure of Al 7 Te, 0 (R32-D^; a = 1439.5 pm, c = 1793.2 pm, Z = 6, R = 0.03) is a distorted defect variant of a tetrahedral arrangement of the 4H-polytype. The central unit, a double barrelane [Te 4 Al 4 —Al 4 Te 4 ], contains an Al —Al bond of 260 pm, which is somewhat longer (n = 0.83) than an expected single bond (250 pm, n = 1). This homopolar bond disturbs the electrostatically favorable (Al—Te—)" sequence in the structure which is compensated by the occurrence of four-membered Al 2 Te 2 rings. Al 7 Te 10 is a Zintl phase according to l/2{[Al 2+ -Al 2+ ][Al 3+ ] !2 [Te 2 ~] 20 } and exhibits semiconducting and diamagnetic behaviour.

 Title    Zur Bildungskinetik des Zeolithen ZSM-11 On the Kinetics of Formation of the Zeolite ZSM-11  
 Abstract    The synthesis of pentasil ZSM-11 with Bu4N H S 0 4 as template was first optimized in a teflon-coated autoclave of 200 ml volume (163 °C, 3 days) and then transferred to a stirring autoclave of 1000 ml volume. The latter allowed sampling over the period of crystallization. Pure ZSM-11 crystallized at temperatures between 150 and 180 °C. In this range the induction period decreased from 15 to 2 hours while the rate of crystallization was enhanced from 2.5 to 5.6% per minute. From these values energies of activation for nucleation and crystallization were determined (99.8 and 43.4 kJ mol-1).

 Title    Chemie an starren Grenzflächen, 7 [1] Ausgewählte Beispiele der chemischen Grenzflächenmodifizierung von Aerosil Selected Examples of the Chemical Surface Modification of Aerosil  
 Abstract    Aminoaerosil containing primary amino end groups is obtained according (1) by reaction of aerosil with y-triethoxysilylpropyl amine (Table II). The NH r anchor groups are acylated in the usual manner: carbonic acid anhydrides, acid chlorides and acid azides and by application of the carbodiimide method (Table III). Optically active groups and phosphoric acid diestergroups are covalently linked with the surface of aerosil according (2) and (3). Aminoaerosil reacts with vinylsulfones as anchor groups of dyes (Remazol-Dyes) producing a covalent bond according (6). Functional groups linked to the surface of aerosil react "normal" (with respect to homogenous solutions) with group specific reagents. Examples: bromination, ozonization of C—C double bonds, hydrolysis of phosphoric acid esteramidates and surface bound chloroamine-T groups. "Interparticular" reactions of modified aerosil are not observed. But aerosil with electroactive groups are electroreduced using Hg-or Pb-electrodes. The optical induction of the catalytic hydrogenation of prochiral defines using palladium deposited on chiral modified aerosil surfaces is low (ca. 1%). Some analytical methods are presented, which are recommended for the determination of the amount of functional groups bound to the surface.

 Abstract    'butylaniIin und rbu4-bmae-H2 = l,2-Bis(2-mercapto-3,5-di-'butylaniIino)ethan sowie ihrer Eisen-, Ruthenium-und Zink-Komplexe [Fe(CO)2(1)u2-ina)2], [Zn('bu2-ma)2] und [RuL2('bu4-bmae)], L = CO, PMe3, PPh3 Transition M etal Complexes with Sulfur Ligands, XXXII* Synthesis of the Sterically D em anding New Thiolate-am ine Ligands fbu2 -ma-H = 2-Mercapto-3,5-di-fbutylaniline and 'bu4-bm ae-H2 = l,2-Bis(2-m ercapto-3,5-di-fbutylanilino)ethane as well as of their Iron, Ruthenium and Zinc Complexes [Fe(CO)2 (fbu2-m a)2], [Zn('bu2-ma)2] and [RuL2 ('bu4 -bmae)], L = CO , PM e3, PPh3 In order to obtain soluble com plexes containing sterically protected metal centers the new bi-and tetradentate thiolate amine ligands 2-m ercapto-3,5-di-'butylaniline (-rbu2-m a-H) and l,2-bis(2-m ercapto-3,5-di-rbutylanilino)ethane (= 'bu4-bm ae-H 2) were synthesized. 'bu2-ma-H reacts with FeCl2 • 4 H 20 and CO to give [F e(C O)2(T3u2-m a)2], with Z n(ac)2 • 2 H 20 [Zn(rbu2-m a)2] is obtained whose acid hydrolysis and reaction with H 2S, respectively, yield pure rbu2-ma-H. The condensation o f 'bu2-ma-H with glyoxal yields the respective bis-benzthiazolidine, which is re­ duced by L iA lH 4 in the presence o f N a[N (SiM e3)-,] to rbu4-bmae-FL. rbu4-bm ae-Li2 reacts with [Ru(C O)3(THF)C12], [R u(PM e3)4Cl2] and [Ru(PPh3)2(C H 3C N)2Cl2], respectively, to yield [R u(L)2('bu4-bm ae)j (L = CO , PM e3, PPh3). The com plexes are more soluble in organic solvents than the corresponding unsubstituted bmae com plexes, bm ae2-= l,2-bis(2-m ercaptoanilino)-ethane(2—).
