 Title    Chiral Thioaldehyde Complexes of Rhenium, X-Ray Structure Determination of [Cp(NO )(Ph3P)R e(i/2-S=CHPh)]PF6 [1]  
 Abstract    Chiral thiolate com plexes [C p(N O)(Ph3P)R eSC H 2R] (R = Ph, 4-C6H 4Cl, 4-C6H4OM e, H, Me) are obtained from [C p(N O)(Ph3P)R eC H 3] by acid cleavage in the presence of thiol and subsequent deprotonation. Small amounts of (chloromethyl)thioether com plexes [C p(N O)(Ph3P)R eS(C H 2C l)C H 2R ]BF4 are formed when dichloromethane is used as a sol­ vent in this reaction. Hydride abstraction using [Ph3C]PF6 converts the thiolate com plexes into ionic thioaldehyde com plexes [C p(N O)(Ph3P)Re(?72-S=CHR)]PF6. These are obtained as pure (RR.SS)-diastereom ers as shown spectroscopically and by X-ray structure determ i­ nation of [C p(N O)(Ph3P)Re(?/2-S=CHPh)]PF6. Crystals are monoclinic, space group 12/a (No. 15), a = 25.877(3), b = 18.785(2), c = 13.768(1) A , ß = 104.93(1)°, Z -8.

 Title    Photoreactivity of Coordinated Phenylhydrazine. Intraligand Excitation of ReCl(CO)3(PhNH-NH2)2  
 Abstract    The complex of ReCl(CO)3(PhNH-NH2)2 shows an absorption band at A max = 272 nm which is assigned to an IL (intraligand) transition of the coordinated phenylhydrazine. Upon IL excitation the complex undergoes a decomposition with 4> = 0.03 at Ajrr = 280 nm.

 Title    Tuning the Steric and Electronic Properties of Chiral Rhenium Thiolate Complexes [1]  
 Abstract    Reaction of the complex [CpRe(NO)(CO)2]BF4 with triisopropylphosphine gives the chiral CO substitution product [CpRe(NO){P(/-Pr)3}(CO)]BF4. The corresponding triphenylphos-phite complex [CpRe(NO){P(OPh)3}(CO)]BF4 may be obtained by oxidative CO removal. Reduction of the remaining CO ligand with NaBH4 furnishes the corresponding methyl com­ plexes [CpRe(NO)(L)(CH3)]. The structure of [CpRe(NO){P(/-Pr)3}(CH3)] was determined: triclinic space group PI (No. 2), a = 8.442(4), b = 9.582(5), c -11.820(8) A, a = 81.81 (4), ß = 87.18(4), 7 = 63.87(5)°, Z = 2. Reaction of the methyl complexes with HBF4 in the presence of thiols gives, after chromatographic workup, the thiolate derivatives [CpRe(NO)(L)(SR)] (L = CO, P(OPh)3, P(/-Pr)3, R = CH2Ph, CH2(4-C6H4C1), CH2(4-C6H4OMe), CH3, C2H5). The structure of [CpRe(NO){P(/-Pr)3}(SCH3)] was determined: monoclinic space group P2i (No. 3), a = 7.0515(7), b = 17.3469(10), c = 7.9727(7) Ä, ß = 114.021(7)°, Z = 2. In both structures, a significant opening of the angle N-Re-X (X = C, S) suggests that antibonding interactions between orbitals of the ligand X and the second-highest MO of the [CpRe(NO)(L)] complex fragment are avoided.

 Title    Synthesis and Electronic Spectra of Tricarbonylrhenium(I) Chloride Complexes with 9,10-Phenanthrenequinone and 9,10-Phenanthrenequinone Diimine as Acceptor Ligands  
 Abstract    The complexes Re(L-L)(CO)3Cl with L-L = 9,10-phenanthrenequinone (PHQ) and 9,10-phenanthrenequinone diimine (PHI) were prepared and characterized spectroscopically. Both compounds show intense Re(I) to L-L metal-to-ligand charge transfer (MLCT) absorptions. In chloroform, the M LCT bands appear at 711 nm (L-L = PHQ) and 553 nm (L-L = PHI).

 Title    Phosphinsubstituierte Chelatliganden, II [1] Thiocarbamoylphosphinsulfid-und -oxid-Komplexe des Mangans und Rheniums Phosphine Substituted Chelate Ligands, II [1] Thiocarbamoylphosphine Sulfide and Oxide Complexes of Manganese and Rhenium  
 Abstract    Thiocarbamoylphosphine sulfides la-c and oxides 2a-c are ambidentate chelating ligands which may form monomeric or dimeric complexes with carbonylmetal halides. The reaction of la-c with ClMn(CO)s and ClRe(CO)s yields the monomeric cw-tetracarbonyl complexes 3a-c and 4a-c with S,S'-coordination. The phosphine oxides 2a-c first form tetracarbonyl complexes which dimerize spontaneously under loss of CO to give the anfi-/ac-tricarbonyl complexes 6a-c and 6 a with bridging three-coordinate sulfur. On refluxing in n-hexane solution, 8a-c and 4b, c are converted into the corresponding dimers 7a-c and 8 b, c. Dissolving of 7 b, c in CH2C12 leads to re-formation of 8 b, c, the free ligands lb, c and inorganic manganese compounds.

 Title    Zweikernige Mangan-und Rheniumkomplexe mit gemischt aliphatischen-aromatischen Kohlenwasserstoffbrücken Dinuclear Manganese and Rhenium Complexes with Mixed Aliphatic-Aromatic Hydrocarbon Bridges  
 Abstract    The symmetrically hydrocarbon-bridged complexes (OC)5M -(C H 2)n+1-X -(C H 2)n+|-M (CO)5 [n = 1, X = 1,4-C6H4, M = Mn (2a), M = Re (3a); n = 2, X = 1,4-C6H4, M = Mn (2b), M = Re (3b); n = 1, X = 1,3-C6H4, M = Mn (5a), M = Re (6a); n = 2, X = 1,3-C6H4, M = Mn (5b), M = Re (6b); n = 1, X = 1,2-C6H4, M = Mn (8a), M = Re (9a); n = 2, X = 1,2-C 6H4, M = Mn (8 b), M = Re (9b)] are obtained by the reaction of the bistriflates X[(CH2)"-C H 2-0 S 0 2CF3]2 [X = 1,4-C6H4, n = 1 (la), n = 2 (lb); X = 1,3-C6H4, n = 1 (4a), n = 2 (4b); X = 1,2-C6H4, n = 1 (7 a), n = 2 (7 b)] with the carbonyl metalates [M(CO)5]" (M = Mn, Re) in THF and dimethyl ether, respectively. According to an X-ray structural analysis 8a crystallizes in the triclinic space group PI with Z = 2. Depending on the solvent, the reaction of 7 a with [Mn(CO)5]" affords also the cyclic carbene complex 10 a. The behavior of the manganese compounds toward CO has been investigated exemplarily in the case of 8 a and leads to the diacyl complex l,2-C6H4[CH2CH2C (0)M n(C 0)5]2 (11). Upon reaction with Na2C 0 3/CH30 H 11 is con­ verted to give the corresponding diester 1,2-C6H4[CH2CH2C (0)0 C H 3]2 (12).

 Title    Zur Existenz von [ReNCl4.nF,|]' (n = 1-3) Nitridorhenat(VI)-Gemischt- ligandkomplexen -Eine EPR-Untersuchung EPR Evidence of [ReNCl4_ "F J~ (n = 1-3) Nitridorhenate(VI) Mixed-Ligand Complexes  
 Abstract    The formation of mixed-ligand complexes of the type [RevlNCl4_"Fn]_ (n = 1 -3) during the reaction of [ReVINCl4]~ with [ra-(C4H9)4N]F, KF, and HF is reported. Evidence of the individual mixed-ligand compounds is given by their EPR spectral data. In frozen solutions a specific dependence of the EPR data on the composition of the coordination sphere could be detected. This is shown (i) by a nearly linear dependence of gy and A| Re on the Cl/F-content of the [ReVINCl4_"F"]-unit (additivity rules) and (ii) by well-resolved l9F hyperfine splittings.

 Abstract    The coordination of tertiary phosphinothioform-amides and the isomeric S-alkyl phosphinothioform-imidates to BrRe(CO) 5 gives the /ac-bromotricar-bonylrhenium complexes la, b and 2a, b with P,S-chelate ligands. Unlike the analogous manganese complexes, the NMR spectra of dissolved lb and 2a, b show a splitting of the N-alkyl ('H, 13 C) and phosphorus signals indicating E/Z isomerisation of the ligands.

 Title    Synthesis and Spectroscopic Properties of 1,2-Diiminetricarbonyl- rhenium(I)chloride Complexes with Aliphatic Diimines (or 1,4-Diaza-l,3-butadienes) as Ligands  
 Abstract    Re(l,2-diimine)(CO)3Cl complexes with the aliphatic bidentate ligands diiminosuccino-dinitrile (DISN), benzilbisanile (BEAN), bisacetylbisanile (BABA), and benzildiimine (BE­ DIM) are reported. The compounds show Re(I) to 7r*(diimine) metal-to-ligand charge transfer (MLCT) absorptions in the visible spectral region. The energy of these MLCT-transitions de­ creases in the series BABA > BEDIM > BEAN > DISN, depending on the 7r* acceptor properties of the coordinated diimine ligands. The maxima of these CT bands undergo a solvent-dependent shift (negative solvatochromism), which indicates a partial charge redistribution in the excited state. The compounds are not photoluminescent at room temperature and 77 K.

 Abstract    The addition o f pentacarbonylrhenate to [(OC)3M n(thiophene)]+, [(OC)3M (^6-C6H 4R2)]+ (M = Mn, Re; R = H, Me, Cl) yields the er,7r-hydrocarbon bridged complexes (OC)3MnGu-774:/71-C4H 4S)Re(CO)5 and (OC)3M(Ju-^6:7 1-C6H 4R 2)Re(CO)5, respectively. The latter complexes have also been obtained from (OC)5M F B F 3 (M = Mn, Re) and C6H 5Re(CO)5. The fluxional behaviour o f the cyclohexadienyl bridged complexes is probably due to a 1,2-shift of the Re(CO)5 group. The reaction o f [Re(CO)5]-with [(/;5-C5H 5)Fe(^6-/?-C6H 4(R)Cl)]+ (R = H, Me, Cl) proceeds with substitution o f chlorine to give the heterobimetallic compounds [(75-C5H 5)Fe[^-/76^ 1-C6H 4(R)]Re(CO)5]+.
