    Description / Table of Contents: Summary Arsenictris(trifluoroacetate) (1) crystallizes monoclinic in the space group Cc witha=1229.3,b=1697.9,c=1243.5 pm, β=110.01°, andZ=8. The trifluoroacetic acid ions acts as chelating ligands. Additionally they are bridging crystallographic independent molecules. As has a coordination number of 3+3(+2). The unit cell contains two sets of chirameres.
    Notes: Zusammenfassung Arsen-tris(trifluoracetat) (1) kristallisiert monoklin in der Raumgruppe Cc mita=1229.3,b=1697.9,c=1243.5 pm, β=110.01° undZ=8. Die Trifluoracetatanionen fungieren gegenüber As als zweizähnige Liganden und verknüpfen die beiden kristallographisch unabhängigen Moleküle zusätzlich intermolekular. As erreicht dadurch gegenüber O die Koordinationszahl 3+3(+2). Die Elementarzelle enthält zwei Sätze von chirameren Molekülen.

    Notes: Substituted Alkinyles as Axial Ligands at Hemine Like Bound Iron(III) - Incorporation into a Spectrochemical Series.Substituted lithium alkynyles Li—C≡C—R (R = tBu, Ph, p-Cl—C6H4, Me3Si, iPr3Si, Ph3Si) react with the hemine like macrocyclic iron(III) complex 6,13-di(ethoxycarbonyl)-5, 14-dimethyl-1, 4, 8, 11-tetraazatetradeca-4,6,12,14-tetraenato[2-]iron(III)-iodide (formula 2;) in tetrahydrofuran to form anionic low-spin di-adducts [fe(C≡C—R)2]-. The incorporation of the alkynyles into a spectrochemical series of the axial ligands (studied by the sharp equatorial-ligand-to-metal CT absorption band) results in the wavelength-sequence (nm): OH- (≍ 510) « N3- (≍ 625) 〈 tBu—C≡C- (664) 〈 NH3 (666) 〈 Ph—C≡C- (692) 〈 Ph—NH2 (695) 〈 Me3Si—C≡C- (698) 〈 SCN- (713) 〈 Ph3Si—C ≡ C- (716) 〈 CN- (739) 〈 4-picoline (759) 〈 pyridine (765) 〈 nicotinamide (776) 〈 methylnicotinat (788) 〈 pyrazine (798) and points to a significant π-acceptor ability of the silyl substituents.
