 Title    Synthese und Molekülstruktur der dreikernigen Cluster-Verbindung (^-C5Me5)IrFea(CO)9 Synthesis and Molecular Structure of the Trinuclear Cluster Compound (^ 5 -C5Me5)IrFe2(CO)g  
 Abstract    Reaction of triirondodecacarbonyl (1) with the dinuclear chloroiridium complex [(?? 5 -C5Me5)Ir(//-Cl)Cl]2 (2) in benzene at 50 °C yields the novel mixed iron iridium cluster of composition (rj 5 -C&Mes)IrFe2(C0)9 (8) the molecular structure of which has been established by X-ray diffraction methods. The mononuclear half-sandwich complex (j7 5 -C5Me5)Ir(CO)2 (4) present in the reaction mixture was found to represent the immediate precursor of the cluster compound 8.

 Title    Darstellungen und Strukturen viergliedriger Metall-Stickstoff-Ringe Preparations and Structures of Four-Membered Metal-Nitrogen Rings  
 Abstract    Ph 3 P=NSiMe 3 (1) reacts with InCl 3 , SnCl, and FeCl, to yield (Ph,P=N) 2 (InCl 2) 2 • 2 DMF (2a), (Ph 3 P=N) 2 Sn 2 Cl 4 • 2 CH 3 CN (3a) and (Ph 3 P=N) 2 (FeCl 2) 2 (4). The X-ray single crystal structures of 2a, 3a and 4 are reported. The compounds form four-membered rings consisting of alternating metal and nitrogen atoms. 2a and 4 are symmetrical, but 3a has both a Sn(II)Cl and a Sn(IV)Cl 3 group in the four-membered ring.

 Abstract    By means of UV photoelectron spectroscopy (UPS) the electronic structures of [Fe^3.C3H5(CO)3X], [Fe^3-(2-CH3C3H4)(CO)3X] (X = Cl, Br, I) and [Co(C3H5)(CO)3] have been studied. Detailed assignments are possible and surprisingly low ionization energies (as low as 8.19 eV) are found for iodine lone pair type Orbitals. From the spectra a large difference in n backbonding is found between the cobalt and iron complexes.

 Title    Eine synthetische Spezies zum Mineral Howardevansit mit Eisen anstelle von Kupfer: NaFe3V 30 12  
 Abstract    Single crystals of NaFe3V30 12 have been prepared by solid state reaction below the melt­ ing point of the reaction mixture. This compound is isotypic to the mineral Howardevansite but shows lower triclinic symmetry, space group C }-P 1 , a = 6.757(2), b = 8.155(2), c = 9.816(3) Ä, a = 106.05(2), ß = 104.401(9), y = 102.09(2)°, Z = 2. The acentric space group is caused by the sodium positions, all other atoms comply with the space group PI of Howarde­ vansite. The different ions are coordinated by O2-forming V 0 4 tetrahedra, FeOfi octahedra, trigonal FeOs bipyramids and irregular NaOs and NaOy polyhedra, respectively. The crystal chemistry is discussed with respect to Howardevansite.

 Title    Offene und geschlossene Triferriophosphonium-Salze und Triferriophosphane O pen and Closed Triferriophosphonium Salts and Triferriophosphines  
 Abstract    The reaction of P(SiM e3)3 with an excess of C pFe(CO)2X (X = Cl, Br) through the action o f water gives the triferriophosphonium salt [{CpFe(CO)2}3PH]2FeX4 together with ferrocene as by-product. The cation of the salt can be deprotonated by D B U to afford the unstable triferriophosphine {CpFe(CO)2}3P. Its subsequent realkylation with RX (R = Me, CH2Ph; X = I, Br) leads to alkyltriferriophosphonium salts [{CpFe(CO)2}3PR]X. Photolysis of [{CpFe(CO)2}3PH]2FeX 4 induces the elimination of one CO group, and the CO-bridged and partly closed complex [{//-CO(CpFeCO)2}{CpFe(CO)2}PH]2FeX 4 is formed, the cation of which can also be deprotonated to give the corresponding m onobridged phosphine (w-CO(CpFeCO)2}{CpFe(CO)2}P. Both PH-phosphonium salts undergo a hydrogen-chlorine exchange reaction to give the P -C l analogues [{CpFe(CO)2}3PCl]2FeX4 and [{//-CO (CpFeCO)2}{CpFe(CO)2}PCl]2FeX 4. The IR and NM R spectra of all species as well as the X-ray structure analyses of the open and closed P -H functional com plexes are reported and discussed.

 Abstract    Single crystals of (C u ,F e)3-63M o30 12 have been prepared by crystallisation from melts. X-ray investigations lead to orthorhombic symmetry, space group D : 2-P 2 12121, a = 5.0952(8), b = 10.637(2), c = 17.881(3) A , Z = 4. (C u ,F e)363M o3O i2 is isotypic to Cu385M o30 12 or (C u,Z n)3 75M o30 12. M olybdenum shows tetrahedral coordination by oxygen.

 Title    Über die Kristallstrukturen der Tellurate Pb3Fe2Te20 12 und Pb2CoTe06  
 Abstract    Pb3Fe2Te20 |2 (I) and Pb2C oT e06 (II) have been prepared by crystallization from melts. Single crystal X-ray investigations led to monoclinic (I) and tetragonal (II) symmetry, space groups Cs-Cc and D{J-I4/mmm. Lattice constants I: a = 9.866(3), b = 15.332(4), c = 7.172(2) A, ß = 111.34(3)°, Z = 4. II: a = 5.661(5), c = 8.004(7) A, Z = 2. (I) represents a new crystal structure, characterized by a network of octahedra occupied by Fe + and Te6+ in a disordered manner. The centres of negative charge of the lone pairs of Pb2+ in I are estimated by Coulomb term calculations. II belongs to the elpasolithe type.

 Title    Photoredox Decomposition of [Cobalamin-^-NC-Fen(CN)5]3* Induced by Metal-to-Metal Charge Transfer Excitation  
 Abstract    In the presence of oxygen aqueous solutions of the binuclear complex [cobalamin-^-NC-Fe(C N)5]3' undergo a redox photolysis (0 ~ 2 x 10'3 at Airr = 405 nm) which yields aquocoba-lamin and [Fe(C N)6]3\ It is suggested that this photoreaction is induced by direct metal-to-metal charge transfer (M M CT) excitation. On the contrary, [cobalamin-fx-NC-Ru(CN)5]3' is photo-inert because a reactive MMCT state is not accessible.

 Title    Über neue zweikernige Metallcarbonylkomplexe mit Cyclohexadienyl-cycloheptatrien-und Cyclohexadienyl-isonitril-Brücken On New Dinuclear Metal Carbonyl Complexes with Cyclohexadienyl Cycloheptatriene and Cyclohexadienyl Isonitrile Bridges  
 Abstract    The reactions of the electrophilic [C6H7Fe(CO)3] + -and [C6H7Fe(CO)2CNEt]+-cations with theextremely nucleophilic [C7H7Fe(CO)3] _ -anion lead to the formation of the dinuclear cyclohexadienyl cycloheptatriene bridged complexes (OC)3FeC6H7-C7H7Fe(CO)3 and EtNC(OC)2FeCeH7-C7H7Fe(CO)3. In a similar reaction the tricarbonyl cation [CeH7Fe(CO)3] + with [Cr(CO)5CN] _ yields the dinuclear cyclohexadienyl isonitrile bridged compound (OC)3FeC6H7-NCCr(CO)5. The mass, IR and NMR data of the new complexes are reported.
