| Übergangsmetall-Methylen-Komplexe, X [1] Methylen-und Alkyl-Eisen-Komplexe aus Diazoalkanen. Molekülstruktur von //-Carbonyl-//-feri-butoxycarbonyl-methylen- bis [carbonyl(^ 5 -cyclopentadienyl)eisen] (Fe-Fe) Transition Metal Methylene Complexes, X [1J Methylene and Alkyl Iron Complexes from Diazoalkanes. 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'. | | |

| Tuning the Energy of the NIR Absorption of Dinuclear Triphos-Cobalt-Complexes  | | | Abstract
| Dinuclear Co(III) complexes of the type [(triphos)Co(C6X2Z' Z2Z3Z4)Co(triphos)]2+ (Z1 ~4 = O, NR, S; R = H, Me; X = H, Cl, Br, I; 1 -62+) have been prepared and characterized by MS, IR, NMR, cyclovoltammetric and UV/VIS/NIR measurements and by X-ray analyses (12+, 3a2+ and 42+). Their redox behaviour and the energy of their low energy LMCT bands was studied and compared to the properties of the mononuclear complexes [(triphos)Co(C6H4Z 'Z 2)]+ (Z1-2 = O, NH, S). | | |
