 Abstract    {Cp(Ph,P)N i}SnClJ <MejSl>;E > I H r [Cp4(Ph3P)3Ni5Sn6Se9] 4 Zur Aufklärung der M olekülstruktur von 4 fer­ tigten wir eine Röntgenstrukturanalyse an. Die Daten zur Strukturbestimmung sind in Tab. I zu­ sammengefaßt. Tab. II enthält die wichtigsten Bindungsparameter von 4. Die Lageparameter der Schweratome sind in Tab. III aufgelistet. Nach dem in Abb. 1 dargestellten Resultat der Strukturuntersuchung läßt sich der Aufbau von 4 folgendermaßen beschreiben: Sechs Zinn-(Sn 1 -S n 6) und sechs Selenatome (S ei, Se2, Se3, Se7, Se8, Se9) bilden einen zwölfgliedrigen Sn6Se6-He-terocyclus, in welchem eine alternierende A nord­ nung von Sn-und Se-Atomen vorliegt (S n-S e: 251,2(2)-261,2(2) pm). Zusätzliche Selenatome (Se5, Se6, Se4) verbinden die im Ring benachbar­ ten Atome S n l-S n 2 , S n 4 -S n 5 und S n 3 -S n 6 (S n-S e: 257,2(2)-268,7(2) pm). Alternativ dazu kann das Sn-Se-Teilgerüst auch so verstanden werden, daß drei Sn2Se2-Vier-ringe (Sn 1, Se3, Sn2, Se5; Sn3, Se4, S n 6, Se8 und S n4, Se 1, Sn 5, Se6) über die Zinnatom e durch /r -Selen-Brücken (Se2, Se7, Se9) m iteinander ver­ knüpft sind. Drei der Zinnatome des Gerüsts (Sn 2, S n 3 und Sn4) sind zusätzlich an Nickelatome ter­ minaler {Cp(Ph3P)Ni}-Gruppen gebunden. Im Zentrum des Sn6Se9-Käfigs findet man ein Nickel­ atom (Ni 5), welches einerseits von drei Se-Ligan-den (Se4, Se5, Se6) koordiniert wird (N i-S e: 241,2(3)—242,5(2) pm) und andererseits an eine CpNi-Einheit (Ni 1) gebunden ist. Zusätzlich wer­ den N il und N i5 von drei /r-Sn-A tom en (S n l, Sn 5, Sn 6) verbrückt. Dadurch erhält Ni 5 die K o­ ordinationszahl sieben und das an Cp gebundene Ni 1 die Koordinationszahl fünf. Abb. 2 veranschaulicht die Koordinationsver­ hältnisse der beiden zentralen Ni-Atome in 4. Es wird dabei deutlich, daß die Ligandenatome Sn 1, S n 5 und S n 6 einerseits und Se4, Se5 und Se6 an­ dererseits in zum Cp-Ring parallelen Schichten an­ geordnet sind. Die aus den Atomen Sn 1, Sn 5 und Sn 6 bzw. Se4, Se5 und Se6 gebildeten Dreiecke sind um ca. 30 bzgl. der N i-N i-A chse gegenein­ ander verdreht. Somit besitzt Ni 5 ein Sn6Se6-Ko-ordinationspolyeder, das zwischen trigonalem Prisma und Oktaeder einzuordnen ist. Nach den konventionellen Abzählregeln erge­ ben sich für die zentrale Ni2-Einheit 34 Valenzelek­ tronen. Demzufolge ist zwischen Ni 1 und Ni 5 eine 696 N otizen [Cp4(P h 3P)3N i5Sn6Se9] R aum gruppe Cc M eß tem p eratu r 183 K G itterk o n stan ten a 1630(1) pm b 2584(1)p m c 2078(2) pm a 90° ß

 Title    Reversible Öffnung von Metall-Metall-Bindungen: Quantitative Untersuchung des RingÖffnungsgleichgewichts von [Cp'(CO)2Mn]2SeAryl+ Reversible Opening of Metal Metal Bonds: Quantitative Analysis o f the Ring Opening Equilibrium for [Cp'(CO)2Mn]2SeAryl+  
 Abstract    The com pounds [Cp'(CO)2Mn]2S eR + are isoelectronic analogues o f the well known "inide-ne"-species [L"M]ER (E = P, As, Sb, Bi). While these latter "inidene" com pounds exist in an open form with no metal-metal-interaction and the main group atom in a trigonal planar envi­ ronment allowing for a three-center-4 ^-system M—E—M, their isoelectronic selenium ana­ logues generally show equilibria between the "inidene"-type metal metal non bonded forms and their metal metal bond closed cyclic isomers. In a valence bond picture the four electrons, delocalized in the three-center-4 ^-system o f the open isomers, are localized in the closed ones: two in the metal metal bond and two as a lone pair at a pyramidally coordinated selenium center. The corresponding equilibria are quantitatively analyzed for [Cp'(CO)-,Mn]-,SeR + (R = ' C F j -Q H , (1), /'C H ,-C 6H4 ('Tol) (2), °CH3-C !,H4 (°Tol) (3)) by U V /V IS spectroscopy o f their solutions at different temperatures. The ring opening process which corresponds to the reversible opening o f a metal metal bond is found to be entropically driven with reac-tion-entropies o f around 25 [JK-lm ol-1]. Correspondingly, imposing steric hindrance on R, [Cp'(CO)2Mn]2SeM es+ (4) yields a stable bond opened "inidene"-type com pound. Reducing steric hindrance in [Cp'(CO)2Mn]2Se'Pr+ (5) gives the bond closed form as the only detectable isomer.

 Abstract    The highly reactive arene iron complex [(/74-toluene)(?76-toluene)iron] allows the formation o f C4-units from alkynes below room temperature. By this route butadiene-, cyclobutadiene-, and ferracyclopentadiene(arene)iron complexes are accessible. Synthesis, structure and the properties o f one example each are reported. Ferracyclopentadienes are potential interme­ diates for the catalytic cyclotrimerization o f alkynes in the coordination sphere o f arene iron complexes.

 Abstract    Reactions o f Cul with N-methylpyrazinium iodide, (pyr)I, N-methyl-4,4'-bipyridinium iodide, (bp 4)1 and N-methyl-2,2'-bipyridinium iodide, (bp 2)1, in organic solvents led to three novel types o f copper(I) complexes o f stoichiometries (pyr)Cu2I3, (bp4)C u3I4 and (bp2)C u2I3. In all o f them the cations are n-a-bonded to copper(I) through donation o f their unshared electron pairs. (pyr)Cu2I3 crystallizes with an ionic structure (trigonal, R 3 c , hexagonal axes a -3053(2), c = 671.9(3) pm, Z = 18). Polymeric cations i[((pyr)C uI3/3)3]3+ and anions i[C u I4/2]-form parallel rod packings. The structure m otif o f the cations can be described as a columnar part o f the ß-Cu\ structure in which the copper and iodine atom s are also arranged to Cu3I3 rings. The crystal structure o f (bp4)C u3I4 (triclinic, P I, a = 938.8(2), b = 980.0(4), c = 1070.1(3) pm, a = 73.56(3), ß = 75.79(2), y = 89.50(3)°, Z = 2) is built up by uncharged chains i[(C uI4/3)(CuI3 3I1/2)((bp4)C uI2/3I1;2)]. The trinuclear units (bp4)C u3I4 are connected via com ­ mon iodide edges. The copper halide connection m otif o f the polymeric com pound has some features in com m on with the "stair" and "cube" structures o f adducts o f Cul with unidentate, neutral P-, As-or N-bases. The com pound (bp2)C u2I3 (m onoclinic, P 2 ,/«, a = 1054.0(2), b = 1034.8(3), c = 1512.6(3) pm, ß = 108.10(2)°, Z = 2) has a structure, in which two edge-sharing (C ul4,2)-tetra-hedra and two approximately planar (C u l2/2(bp2))-units form tetranuclear molecules (bp2)2Cu4I6. These are linked to chains with a "stair" m otif by intermolecular Cu • • • I contacts.

The Crystal Structures of [Mes(Cl)InN(SiMe3)2]2 and {/-Pr2In[N(H)/-Bu]2In(Cl)/-Pr}  
 Abstract    Alkyl(Aryl)chloroindium Amides, Isomers, Crystal Structure [(PhCH2)2InN (H)/-Bu]2 (3) and [PhCH2(C l)InN(SiM e3)2]2 (4) have been prepared by the reaction o f (PhC H 2)2InCl with L iN (H)/-B u and o f PhCH2InCl2 with N aN (S iM e3)2, respective­ ly. 3 could be isolated in two isomers, while 4 forms only one chloro-bridged isomer in solution and in the solid state. The possibility o f a chloro-bridged alkyl(aryl)chloroindium amide is also realized in [M es(Cl)InN (SiM e3)2]2 (2), as shown by X-ray analysis. The reaction o f a 1:1-m ix­ ture o f z'-Pr-JnCl/z'-PrlnCU with LiN(H)r-Bu leads to all three possible compounds: [/-Pr(Cl)InN(H)/-Bu]2 (1), {/-Pr2In[N(H)/-Bu]2In(Cl)/-Pr} (5), and [/-Pr2InN (H)/-Bu]2 (6). Two isomers o f the new com pound 5 are detectable in solution. The crystal structure has been de­ termined for the less sterically hindered isomer 5a, which forms hydrogen-bridged (C l -H -N -bridge) infinite chains along the c-axis.

 Abstract    Zinc, cadmiun and mercury dihalide react with 4-acetylpyridinthiosemicarbazone (4-aptsc) to give complexes with 1:1 and 2:1 ligand/m etal stoichiom etric ratios. These metals are effec­ tive templates for the Schiff-base condensation o f 4-acetylpyridine with semicarbazide to give the complexes [M (4-apsc)XJ and [M (4-apsc)2X 2] where M = Zn, Cd or Hg and X = Cl, Br or I. These com pounds were characterized by elemental analyses, conductivities measurements, IR and l3C, 'H N M R spectra. The zinc chloride and bromide com plexes o f benzalthiosem icarbazone (btsc) have been pre­ pared and characterized by X-ray measurements. The com pounds Zn(btsc)2Cl2 and Cd(btsc)2Br2 are isostructural and crystallize in the space group P 2j/«. The crystal structure o f the chlorine derivative has been resolved by single-crystal X-ray diffraction. The zinc centre is in a slightly distorted tetrahedral environment. There are intra and intermolecular hydrogen bonds.

For n = 2, 3 and 4, only the analogues o f 2 could be prepared (3 -5). Treatment o f 1 and 2 with sodium bicarbonate afforded the corresponding betaines Ph2PCH 2PPh2+C H 2CH2COO~ (isolated as a dihydrate 6) and C H 2[PPh2+C H 2C H 2COO"]2 (isolated as the tetrahydrate 7).

 Title    Metallkomplexe in Anorganischen Matrices, 5 [1] Katalytische Silanoxidation an einem heterogenisierten Rhodium-Komplex M etal Complexes in Inorganic Matrices, 5 [1] Catalytic Silane Oxidation at a Heterogenized Rhodium Complex  
 Abstract    A heterogenized rhodium complex, prepared by sol-gel processing of Rh(CO)Cl[PPh2C H 2C H 2Si(OEt)3]2 and Si(OEt)4, is shown to catalyze the conversion of the si­ lanes H4_"SiPh" (n = 1 -3) or (H M e2Si)20 to (poly)siloxanes by air or water. Using T H F as a solvent, the silanoles Ph3SiOH or Ph2Si(OH)2 are obtained instead. The reaction of phenyl-acetic acid or acetic acid with HSiPh3 to give silyl esters is catalyzed by the same com pound.
