    Notes: Abstract A complete theoretical study is carried out of the beta decays of the12B and12N ground states to the12C ground state. We calculated the form factor coefficientsF KLs N (ke, m, n, ρ) using the Cohen-Kurath wave functions. In particular, we obtained reasonable values for the form factor coefficients A F 101 0 and v F 111 0 whose ratio contains the influence of the weak magnetism coupling constant. It is shown that in this way the measurements of the shape factors presented by Wu and coworkers can be explained. In addition, it is demonstrated that the contribution of the term proportional to (WR)2 cannot be completely neglected because of the large end point energyW 0. From our value of v F 111 0 we have derived the radiative widthΓ γ (M1) of the isobaric analogγ transition from the excited state12C* to the ground state of12C. The result is in good agreement with the experimental data. For both beta transitions we have evaluated theft values which are in good agreement with the experimental values. It is confirmed that the difference between theft values for both beta transitions can be accounted for by binding energies effects.

    Description / Table of Contents: About Chemistry and Structure of Olefin-monocyano-dicarbonyl-ferrate AnionsBy the reactions of olenFe(CO)3 [olen = C5H8(isoprene), C7H10(cycloheptadiene-1,3), C8H14(2,5-dimethylhexadiene-1,3)] with sodium bis [trimethylsilyl]amide the new anions [olenFe(CO)2CN]- are formed. All so far known [olenFe(CO)2CN]- complexes [olen = C5H8(isoprene), C7H10[cycloheptadiene-1,3], C4H6(butadiene), C5H8(pentadiene-1,3), C6H8(cyclohexadine-1,3), C6H10(2,3-dimethylbutadiene), C8H8(cyclooctatetraene)] have fluctional structures in solution as shown by 13C NMR spectroscopic investigations. At low temperatures only the isomer exists, in which the CN- ligand and one of the two CO molecules occuppy the basal positions of a square pyramide together with 2 C atoms of the diene part.
    Notes: Bei der Umsetzung von olenFe(CO)3 [olen = C5H8(Isopren), C7H10(Cycloheptadien-1,3), C8H14(2,5-Dimethylhexadien-1,3)] mit Natrium-bis[trimethylsily]-amid werden die neuen Anionen [olenFe(CO)2CN]- gebildet. 13C-NMR-spektroskopische Untersuchungen an sämtlichen bisher bekannten [olenFe(CO)2CN]--Komplexen [olen = C5H8(Isopren), C7H10(Cycloheptadien-1,3), C4H6(Butadien), C5H8(Pentadien-1,3), C6H8(Cyclohexadien-1,3), C6H10(2,3-Dimethylbutadien), C8H8(Cyclooctatetraen)] zeigen, daß diese Anionen in Lösung fluktuierende Strukturen besitzen. Erst bei tiefen Temperaturen tritt jeweils das Isomere auf, bei dem der CN--Ligand und eines der beiden CO-Moleküle in einer quadratischen Pyramide neben 2 C-Atomen des Dienteiles die beiden übrigen basalen Positionen besetzen.

However the solvates Na[Mn2(CO)9CN] · CH3COCH2Cl and Na[Mn2(CO)9CN] · NCCH2Cl are formed with CH3COCH2Cl and NCCH2Cl. Similar adducts are obtained with the Lewis bases CH3COCH3, NCCH3, and O(C2H5)2.

Dagegen führen die entsprechenden Umsetzungen mit CH3COCH2Cl bzw. NCCH2Cl zu den Solvaten Na[Mn2(CO)9CN] · CH3COCH2Cl und Na[Mn2(CO)9CN] · NCCH2Cl. Eine ähnliche Adduktbildung erfolgt auch mit den Lewisbasen CH3COCH3, NCCH3 und O(C2H5)2.
