	Title	^-Olefin-Iridium-Komplexe, XXII [1] C -H -Aktivierung von aromatischen und aliphatischen Solvensmolekülen RH bei der Reaktion von [CpIrCI2 ] 2 mit Butadienmagnesium unter Bildung von [CpIr(773-C4H 7)R] sowie Kristallstruktur von [CpIr(i/3-C4H 7)C6H 5] jr-Olefin Iridium Complexes, XXII [1] C -H Activation of Aromatic and Aliphatic Solvent Molecules RH in the Reaction of [CpIrCl2 ] 2 with Butadienemagnesium with Formation of [CpIr(?;3 -C4 H 7 )R], and Crystal Structure of [CpIr(773 -C4 H 7 )C6 H 5] Activation of C -H , (l-Methylallyl)(pentamethylcyclopentadienyl)iridium-a-organyl Com plexes
	Abstract	Reactions of [CpIrCl2]2 (Cp = ^3-C5M e5) with [MgC4H6 -2 THF]" at low temperature give [CpIr(^4-C4H6)] together with [CpIr(/73-C4H 7)R] compounds, the latter being formed via C -H activation of solvent molecules RH (RH = benzene, toluene, anisole, thiophene, furane, N-methylpyrrole, pentane, cyclohexane. THF). In the case of pyrrole, C -N -activation occurs. The ratio of syn and anti isomers of the 1-methylallyl com plexes as well as the sites o f C -H activation of RH were investigated by NM R spectrometry. An enantiomorphous crystal of [CpIr(773-C4H7)C6Hs] was characterized by X-ray diffraction analysis which reveals trigonal planar coordination at the Ir atom and an exo, syn conformation o f the 1-methylallyl ligand. A mechanism of the reaction which involves 16-electron intermediates is discussed. The corresponding system [CpRhCl2]2/butadienemagnesium/RH gives only [Cp*Rh(>/4-C4H6)], and no C -H activation is observed.

	Title	Oxidsulfidchloride der Lanthanide vom Typ M 4OS4Cl2 (M = L a-N d ) M 4OS4Cl2-Type Oxysulfide Chlorides of the Lanthanides (M = L a -N d )
	Abstract	Oxysulfide chlorides, M4OS4Cl2, o f the lanthanides (M = L a -N d) are obtained upon the oxi dation o f the metals with sulfur in the presence o f MOC1 (or M 20 3) and MC13 in appropriate molar ratios. Additional NaCl or an excess o f MC13 serving as a flux provide even single crys talline material after reactions at 850 °C for seven days in sealed tantalum capsules. The crys tal structure o f M4OS4Cl2 (hexagonal, P 6 3mc, no. 186, Z = 2; M = La: a = 933.19(3), c = 701.22(4) pm, c/a = 0.7514, R = RH = 0.020; M = Ce: a = 925.49(3), c = 694.13(3) pm, c/a = 0.7500; M = Pr: a = 919.72(4), c = 688.53(4) pm, c/a = 0.7486; M = Nd: a = 914.25(4), c = 683.12(4) pm, c/a = 0.7472, R = 0.022, Rw = 0.019) contains isolated 0 2--centered (M 3+)4 te-trahedra which are surrounded by twelve S2-and six Cl-, capping vertices, edges, and faces o f each tetrahedron and linking to other [OM4] units. Basically, the structure is identical to that o f Ba4OCl6 if Ba2+ is substituted by M 3+ and 2/3 o f the CL anions are replaced by S2-to secure charge neutrality in M4OS4Cl2. Different models for the C L /S 2-replacement are presented on the basis o f comparisons o f the Madelung part o f the lattice energy (M A PLE) with the M APLE sum o f the binaries (M 20 3, M 2S3, and MC13).

Ein Ziel unserer Arbeiten war es, das D onor verhalten dieser Systeme gegenüber Fluor-Lewis-Säuren (AsF5, SbF5, BF3) zu untersuchen und die Grenzen zwischen Carbenium-, Sulfoniumsalz-und Addukt-Bildung zu erkennen. Durch Strukturun tersuchungen konnte belegt werden, daß AsF5 aus F2CSCF2S F " abstrahiert unter Bildung des cycli schen Carbeniumions FCSC F2S+ [lb]; nach IR-und 1' 9F-N M R -U ntersuchungen führt die analoge Umsetzung von F 7SCF?S(0")C F7 (n = 0 -2) zu Sul-foniumsalzen FSC F2S(0")CF2+ [lc], während in Sulfoxid-Derivaten die Lewis-Säure an den Sauer stoff unter Bildung von F 2CS(0")CF2S 0 • M F 5 (n = 0 -2) addiert wird.

	Title	Zur Struktur und Dotierung von Selenosilikaten: die Kristallstruktur von Er2S e S i0 4 und Er3 75Ca0 25Se2 75C10 25Si20 7 Structure and Doping of Seleno Silicates: the Crystal Structures of Er2SeSi04 and E r3 7^CaQ 2$Se2 ^C Iq ^Si^O-y
	Abstract	Well-shaped brown and pink isometric crystals were obtained as by-products o f the syn thesis o f erbium selenides from the elements in evacuated and sealed silica ampoules with graphite inlets. They could be identified as erbium seleno m ono-and disilicates by energy dis persive X-ray fluorescence and X-ray structure determination. The monosilicate Er2S e S i0 4 crystallizes isotypically to N d 2S e S i0 4 in the space group Pbcm with the lattice parameters a = 600.2(2), b = 688.0(2), c = 1075.2(2) pm and represents the second known seleno inosilicate o f the rare earths. From X-ray structure analysis an isotypic relation between the disilicate Er3 75Ca0 25Se2 75C10 25Si20 7 and the com pound Sm4S3Si2O v was found, the former crystallizing in the space group 14,/am d with the lattice parameters a -1177.7(2) and c = 1376.5(2) pm. The doping o f the sorosilicate with the elements Ca and Cl originated from contam inations in the graphit inlets used in the procedure.

	Title	Kristallstruktur und hydrothermale Darstellung der Schichtverbindung B e2( P 0 4)(0 H )* 2 H 20 Crystal Structure and Hydrotherm al Synthesis of the Layered Com pound Be2 ( P 0 4 ) (0 H ) * 2 H 20
	Abstract	Colourless monoclinic single crystals of B e2(P 0 4) (0 H) -2 H 20 (space group P 2 Jn) have been prepared under hydrothermal conditions in aqueous solution. Crystal data: a = 631.7(1), b = 1108.7(2), c = 812.7(2) pm, ß = 105.83(2)°, 910 unique reflections, 108 parameters, Rg = 0.0233. P is tetrahedrally coordinated by 4 oxygen atoms. Each of the two crystallographically unique Be atoms has two phosphate oxygen atoms, one water molecule, and one OH group as coordination partners. The tetrahedra share common vertices and build up a two-dim ensionally infinite pattern. The OH group links the two unique Be centered tetrahedra. Loss of water com m ences at 300 °C and is finished at 580 °C.

	Title	Ein neuer Zugang zu ionischen Thionylimiden. Einkristallstruktur von N(CH3)4NSO A New Access to Ionic Thionylimides. Single Crystal Structure of N(CH3)4NSO
	Abstract	Single crystals of N (C H 3)4NSO have been prepared via ion exchange from RbNSO or CsNSO and tetraalkylammonium halides in liquid ammonia and investigated by X-ray single crystal techniques (14, a = 1137.6(1), c = 1134.9(2) pm, Z = 8, T = -1 0 0 °C). The crystal structure of N (C H 3)4NSO is related to the CsCl-type of structure. Using the same preparative route N M e3B zN SO has been obtained. Its lattice powder data (orthorhombic primitive; a = 896.3(2)

	Title
	Abstract	The crystal structure determination of the new rhodium(III)-complex [(DM L)(C5Me5)ClRh](PF6). DML = 1,3-dimethyllumazine, reveals 0 4,N5 coordination of the metal to DML with not very different bond lengths of 213.0(2) pm (R h -N) and 219.2(2) pm (R h -O). This result stands in contrast to the previously reported structure of a cationic dihydrobiopterin bound to [Mo(0)C13] which exhibited a very unsymmetrical chelate ar rangement. Chemical and electrochemical two-electron reduction of the Rh(III) complex led to a very labile Rh(I) species (DM L)(C5Me5)Rh which is distinguished by an intense charge transfer band in the visible. The results confirm the characterization of DML as a weak o donor In acceptor ligand with a rather low-lying tc* orbital.
