    Notes: Die von E. Fischer und G. Bertrand beschriebenen Tribenzal-L-idite erwiesen sich als identisch mit 1.3;2.4;5.6-Tribenzal-L-idit. Unter wenig abgeänderten Versuchsbedingungen entsteht neben dem Tribenzal-L-idit ein Dibenzal-Derivat, welches einen 2.3.4.5-, wahrscheinlich 2.4;3.5-Dibenzal-L-idit darstellt. Es wird auf den unterschiedlichen Verlauf der Acetalisierung des L-Idits mit Benzaldehyd, bzw. Formaldehyd hingewiesen.

    Description / Table of Contents: Synthesis and Molecular Structure of a Metal Cluster with Cubane Structure, [η5-C5H5Mo(CO)3HgMo]4(4)The compound [η5-C5H5Mo(CO)3HgMo]4 has been isolated as an additional product of the reaction between [η5-C5H5Mo(CO)3]2, 2-butenyl chloride, and sodium amalgam. The X-ray structure (R = 0·050) analysis of this novel species revealed that the compound has a slightly distorted cubane structure, for the first time the cubane unit being built up by two different metal atoms (Mo and Hg).
    Notes: Die Verbindung [η5-C5H5Mo(CO)3HgMo]4 (4) wurde als weiteres Produkt der Reaktion zwischen [η5-C5H5Mo(CO)3]2, 2-Butenylchlorid und Natriumamalgam isoliert. Die Röntgenstrukturanalyse dieser neuartigen Spezies zeigt eine leicht verzerrte Cubanstruktur, bei der das Cubangerüst erstmals aus zwei verschiedenen Metallatomen (Mo und Hg) aufgebaut ist. Der R-Wert beträgt 0·050.

    Description / Table of Contents: Investigations on the Catalysis of Ammonia Synthesis and Nitrogen Isotope Exchange by Lamellar Compounds of Graphite with Iron, Ruthenium, and OsmiumThe catalytic activity of transition metal potassium-graphite lamellar compounds for the synthesis of ammonia from the elements and the catalysis of the equilibration by isotope exchange of the isotopic nitrogen molecules are shown to correlate. Connections between the state of metal in the catalyst exist with iron as metal which is shown by Mössbauer spectroscopy and the catalytic activity in relation to the potassium content.
    Notes: Die katalytische Aktivität von Übergangsmetall-Kalium-Graphitverbindungen bei der Synthese von Ammoniak aus den Elementen und bei der Einstellung des Isotopenaustauschgleichgewichts der isotopen Stickstoffmolekeln korrelieren miteinander. Im Falle von Eisen als Metall sind Beziehungen zwischen dem durch Mößbauer-Spektroskopie ermittelten Zustand des Metalls im Katalysator und der katalytischen Aktivität in Abhängigkeit vom Kaliumgehalt erkennbar.

    Description: Round scad exploration by purse seine in the waters of western Philippines was conducted from April 22 to May 7, 1998 for a period of five (5) fishing days with a total catch of 7.3 tons and an average of 1.5 tons per setting. Dominant species caught were Decapterus spp. having 70.09% of the total catch, followed by Selar spp. at 12.66% and Rastrelliger spp. 10.70%. Among the Decapterus spp. caught, D. macrosoma attained the highest total catch composition by species having 68.81% followed by D. kurroides and D.russelli with 0.31% and 1.14% respectively. The round scad fishery stock was composed mainly of juvenile fish (less than 13 cm) and Age group II (13 cm to 14 cm). Few large round scad at Age group IV and V (20 cm to 28 cm) stayed at the fishery. Other fishes caught were: Auxis rochei (0.85%), A. thazard (0.12%), Caranx spp. (0.45%), Emmilichthys nitidus (0.58%), Euthynnus affinis (0.42%), Leiognathus ruconius (0.58%), Loligo sp. (0.31%), Megalaspis cordyla (0.09%), Rastrelliger spp. (10.70%), Sardinella longiceps (0.03%), Scomberoides lysan (0.24%), Selar spp. (12.66%), Sphyraena spp. (0.90%), Thunnus albacares (0.96%) and others (1.02%). Tuna and tuna like fishes such as yellowfin tuna, eastern little tuna, bullet tuna, frigate tuna and oceanic squid are distributed in the upper latitudes of the survey area. On the other hand, round scads, big-eyed scads and Indian mackerels are dominantly present in the lower latitudes of the survey area.

    Description / Table of Contents: The Crystal and Molecular Structure of C7H7RuC7H9 - (1-5-ν- Cycloheptadienyl)(1-5-ν-cyclohepatrienyl)ruthenium(II)The structure of the title compound 5 has been determined by X-ray diffraction. The compound crystallizes in the space group P21/n, a = 644.2 ± 0.1 pm, b = 01775.8 ± 0.2 pm., c = 989.9 ± 0.1 pm, β = 97.72 ± 0.02°, Z = 4 (R = 0.035). The ruthenium atom is coordinated by a cyclohephtadienyl and cycloheptatrienyl ligand, both functioning as five electron ligands. One double bond of the cycloheptarienyl ligand does not interact with the central atom.
    Notes: Mittels Röntgenanalyse wurde die Struktur der Titelverbindung 5 bestimmt.
