    (+)-{1,2-Bis[(2R,5R)-2,5-diethyl-phospho-lan-1-yl]ethane- κ2 P,P′}(≠4-cyclo-octa-1,5-diene)rhodium(I) tetra-fluoridoborate
    (Chester : International Union of Crystallography, 2010) Schulz, S.; Fischer, C.; Drexler, H.-J.; Heller, D.
    The title compound, [Rh(C8H12)(C18H 36P2)]BF4, exhibits a rhodium(I) complex cation with a bidentate bis-phosphine ligand and a bidentate 2, 2-coordinated cyclo-octa-1,5-diene ligand. The ligands form a slightly distorted square-planar coordination environment for the Rh(I) atom. An intra-molecular P-Rh-P bite angle of 83.91 (2)° is observed. The dihedral angle between the P - Rh - P and the X - Rh - X planes (X is the centroid of a double bond) is 14.0 (1)°. The BF4 anion is disordered over two positions in a 0.515 (7):0.485 (7) ratio.

    The close AGN reference survey (CARS) : Discovery of a global [C II] 158 µm line excess in AGN HE 1353−1917
    (Les Ulis : EDP Sciences, 2019) Smirnova-Pinchukova, I.; Husemann, B.; Busch, G.; Appleton, P.; Bethermin, M.; Combes, F.; Croom, S.; Davis, T.A.; Fischer, C.; Gaspari, M.; Groves, B.; Klein, R.; O’Dea, C.P.; Pérez-Torres, M.; Scharwächter, J.; Singha, M.; Tremblay, G.R.; Urrutia, T.
    The [C ii]λ158 µm line is one of the strongest far-infrared (FIR) lines and an important coolant in the interstellar medium of galaxies that is accessible out to high redshifts. The excitation of [C ii] is complex and can best be studied in detail at low redshifts. Here we report the discovery of the highest global [C ii] excess with respect to the FIR luminosity in the nearby AGN host galaxy HE 1353−1917. This galaxy is exceptional among a sample of five targets because the AGN ionization cone and radio jet directly intercept the cold galactic disk. As a consequence, a massive multiphase gas outflow on kiloparsec scales is embedded in an extended narrow-line region. Because HE 1353−1917 is distinguished by these special properties from our four bright AGN, we propose that a global [C ii] excess in AGN host galaxies could be a direct signature of a multiphase AGN-driven outflow with a high mass-loading factor.
