The reaction of Cp(CO)2FeI with 2-ethynyl-pyridine under Sonogashira conditions [5% PdCl2(PPh3)2, 10% CuI, THF-NEt3 (2:1)] afforded the title binuclear μ-pyridyl-vinyl-idene FePd complex (FePd1) as a benzene solvate, [FePd(C5H5)(C7H5N)I(CO)2]·C6H6, in a very low yield rather than the expected iron o-pyridyl-ethynyl complex Cp(CO)2Fe-C≡C-(2-C5H4N). The Fe and Pd atoms in FePd1 are bridged by car...

The structure of the title compound, [Cu(2)I(2)(C(44)H(32)P(2))(2)]·0.67H(2)O, has been determined because of its inter-esting catalytic and optical features. The mol-ecule, which has non-crystallographic C2-symmetry, consists of a core structure of two Cu(I) ions, bridged by two iodide ions. Each Cu(I) ion is also coordinated by one equivalent of the chiral bidentate (R)-BINAP ligand [BINAP = ...

BACKGROUND The efficacy of endodontic irrigation procedures can be compromised by the complexity of the root canal system. Delivering irrigants to the apical third of curved canals presents a particular challenge to endodontists. This study compared the effects of two ultrasonic irrigation techniques on the penetration of sodium hypochlorite into the main canal and simulated lateral canals of c...

Die Langzeitstabilität des optisch transparenten p-Typ-Halbleiters Kupferiodid ist eine aktuelle Herausforderung, da die elektrische Leitfähigkeit von CuI-Dünnfilmen empfindlich auf Umgebungseinflüsse reagiert. Deckschichten aus Aluminiumoxid erhöhen Stabilität beträchtlich. Systematische Untersuchungen Al2O3/CuI-Heterostrukturen in Abhängigkeit der N2- oder O2-Partialdrücke bei Oxid-Abscheidun...
