 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    He(I) and He(II) Photoelectron Spectra of M[Co(CO)4]2 and M[Mn(CO)5]2 Complexes (M = Zn, Cd, and Hg)  
 Abstract    The He(I) and He(II) photoelectron spectra of M[Co(CO)4]2 and M[Mn(CO)ö]2 complexes (M = Zn, Cd, Hg) are reported. Bands attributable to metal-metal bonds, metal d-levels and CO orbitals are assigned in agreement with a semi-ionic model, i.e. M 2+ and [M'(CO)"] -. Relativistic effects prove to be important in assigning these ultraviolet photoelectron spectra.

 Title    Meso-rac-Ph(X)P-(CH2>4-P(X)Ph-Liganden in Komplexen des Typs (CO)4Mas(L-L), Untersuchung der Stereoisomerie durch 31 P{ 1 H}-und "Cj 1 H}-NMR-Spektroskopie [1] Meso. rac-Ph(X)P-(CH2)4-P(X)Ph Ligands in Complexes of the Type (CO)4Mcw(L-L), Investigation of Stereoisomerism by 31 P{ 1 H} and 13 C{ 1 H} NMR Spectroscopy [1]  
 Abstract    By reaction of M(CO)Ö (M = Cr, Mo, W) with the bifunctional aminophosphane Ph(NEt2)P-(CH2)4-P(NEt2)Ph (L-L) octahedral complexes (CO)4Mcw(L-L) are obtained. While it is shown by 31 P{ 1 H} NMR spectroscopy, that these complexes contain meso-and rac-(L-L) to a different extent, there is evidence from 13 C{ 1 H} NMR data obtained for the Mo complex, that the rac-ligand always prevails. As racemisation is observed when the Mo complex reacts with HBr to give (CO)4Mo-cis[Ph(Br)P-(CH2)4-P(Br)Ph] an SN 1 -mechanism is suggested for this reaction.

Molecular Structure of //-Carbonyl-^-Jerf-butoxycarbonyl-methylene- bis[carbonyl(if-cyclopentadienyl)iron] (Fe-Fe)  
 Abstract    The novel doubly bridged /i-methylene iron complexes /M-[C(H)C02R]-^-C0[(??5.C5H5)Fe(C0)]2 (R = C2H5: 3a; R — ^Hg: 3b) have been syn-thesized by low-temperature photolysis of the corresponding alkyldiazoacetates 2 a and 2 b, resp., in the presence of [(r? 5 -CsH5)Fe(CO)2]2 (1) and characterized by means of their analytical data and IR, X H NMR and mass spectroscopy. The geometry of 3 b has been established by single crystal X-ray diffraction techniques. cr-Alkyl iron complexes of the type (^ 5 -C5H5)Fe(C0)2[CHRR'] are accessible from the corresponding diazoalkanes N2 = CRR'.

 Title    Synthese und Charakterisierung von 1,3,5-Hexahydrotriazin-Komplexen des Mo° und Movl  
 Abstract    Organo-substituted 1,3,5-hexahydrotriazine com plexes of the type (R N C H 2)3M o(C O)3 (R = CFI3, / -C 3 H 7 and CH2C6H 5) are obtained by ligand displacement from 7 6-C7H 8M o(C O)3 in high yields. These products have been characterized by 'H. 13C, 95Mo NM R, IR as well as mass spectroscopy and contain an electron-rich M o(C O)3 center bonded to the 1,3,5-hexahydrotriazine 6 e donor via three M o -N bonds. Oxidation o f the Mo° com ­ plex l,3,5-(C H 3N CH 2)3M o(C O)3 with H20 2 under carefully controlled conditions allows iso­ lation of 1,3,5-(CH3N C H 2) 3M o 0 3 containing a M ovl center. Chemical and spectroscopic properties o f these com plexes are compared with those o f related Mo com plexes with neutral macrocyclic ligands containing N 3 donor sets.
