    Description / Table of Contents: Reaction of Chlorine Nitrate with CF3I: Isolation of Trifluormethylchloroiodinenitrate CF3I(Cl)ONO2 and the Crystal Structure of Trifluormethyliodinedinitrate CF3I(ONO2)2CF3I reacts with ClONO2 to Iodine(III)-compounds. After an addition CF3I(Cl)ONO2 is isolated and characterized by vibrational spectra. With surplus ClONO2 it is formed CF3I(ONO2)2.CF3I(ONO2)2 crystallizes monoclinic in the space group P21/c with the cell parameters a = 1 024.3(6) pm, b = 873.5(6) pm, c = 873.4(6) pm and Z = 4.We measered following bonding distances: I—O: 207.3(3) and 220.8(2) pm, I—C: 221.1(4) pm and N—O: from 119.1(4) to 141.5(3) pm.Through an intermolecular I ··· O-contact the central iodine becomes a distorted plane geometry.
    Notes: CF3I reagiert mit ClONO2 in einer oxidativen Additionsreaktion zu Iod(III)-Verbindungen. Das Additionsprodukt CF3I(Cl)ONO2 wird isoliert und schwingungsspektroskopisch charaktersiert. Mit überschüssigem ClONO2 bildet sich CF3I(ONO2)2.CF3I(ONO2)2 kristallisiert monoklin in der Raumgruppe P21/c mit a = 1 024,3(6) pm, b = 873,5(6) pm, c = 873,4(6) pm und Z = 4.Es werden folgende Bindungslängen gemessen: I—O: 207,3(3) bzw. 220,8(2) pm, I—C: 221,2(4) pm und N—O: 119,1(4) bis 141,5(3) pm.Durch einen intermolekularen I ··· O-Kontakt erlangt das zentrale Iodatom eine verzerrt-planare Umgebung.

    Notes: A 4-nitrophenol degrading strain PNP1 isolated from the El-Harrach River near Algiers (Algeria) was studied with respect to its growth behaviour. According to the morphological and biochemical characteristics this strain was assigned to Pseudomonas putida. Besides 4-nitrophenol, the strain also used 1,2- and 1,4-dihydroxybenzene, benzoate, 4-hydroxybenzoate and 3,4-dihydroxybenzoate as sources of carbon and energy, degrading them exclusively via the ortho pathway. Pseudomonas putida PNP1 degrades 4-nitrophenol through a purely oxidative pathway with release of the nitro group as nitrite. During cultivation with 4-nitrophenol in ammonium-containing mineral medium, the strain PNP1 grew optimally at pH 7 and at a temperature between 30 and 35°C and showed stoichiometric nitrite release (at pH 7 and 30°C MONOD model parameters μmax = 0.615 h-1 and KS = 0.145 mg/l). A phenomenological model for the description of growth inhibition at high 4-nitrophenol concentrations was derived (below 400 mg/l only weak inhibition and at 600 mg/l acute toxicity). In ammonium-free medium, the maximum specific growth rate was reduced to 0.318 h-1 and part of the 4-nitrophenol-N was used as the nitrogen source (32% N in biomass and 68% N in nitrite). The yield coefficients of strain PNP1 were smaller in ammonium-free than in ammonium-containing medium (e.g. with 4-nitrophenol YX/S = 0.305 g/g compared to 0.350 g/g), which can be explained by the energy expense for the assimilatory nitrite reduction in the biosynthesis of N-containing cellular compounds. But the oxygen consumption was only slightly influenced by the ammonium content of the cultivation medium (e.g. with 4-nitrophenol YO/S = 1.005 g/g compared to 0.954 g/g).
