    Notes: [Auszug] IN our preliminary report1 on vernalization of mustard (Brassica juncea, Hooker Type 27) it was shown that even seeds previously soaked which remain unsplit during the period of chilling are vernalized. Though the degree of vernalization induced by the same dose of chilling is ...

    Description / Table of Contents: Nitrosyl-Rhenium-Komplexe: Iodonitrosyl-DerivateRe(NO)I52- wurde als Cs+- Rb+- und dipyH+-Salz isoliert. Außerdem wurden das nicht elektrolytische Re(NO)I3L (L = 1,10-Phenanthrolin und 2,2′-Dipyridyl) und [Re(NO)IL2]PtCl6 dargestellt. Aus einer Lösung von Re(NO)(OH)3 in HI wurde eine Verbindung der Formel Re(H2O)(NO)(OH)I2 isoliert, deren Pyrolyse Re(H2O)0.5(NO)(OH)2I ergab. Bestimmung der elektronischen und IR-Spektren sowie der magnetischen Momente wurde durchgeführt. Die Eigenschaften der Iod-Derivate werden mit den entsprechenden der Fluor-, Chlor- und Brom-Komplexe verglichen.
    Notes: The anionic Re(NO)I52- has been isolated as salts of Cs+, Rb+, and dipyH+. The nonelectrolytic Re(NO)I3L (L stands for 1,10-phenanthroline and 2,2′-dipyridyl) and cationic [Re(NO)IL2]PtCl6 have also been prepared. From a solution of Re(NO)(OH)3 in HI, compound of formula Re(H2O)(NO)(OH)I2 has been isolated, pyrolysis of which yielded Re(H2O)0.5(NO)(OH)2I. Measurements of electronic and i.r. spectra and magnetic moments have been carried out. The properties of the iodo derivatives have been compared with those of the corresponding fluoro, chloro and bromo complexes.

    Description / Table of Contents: Nitrosylrhenium-Komplexe: Synthesen, Eigenschaften und Strukturen von OxalatoderivatenDie freie Säure H[Re(NO)(C2O4)(OH)2H2O] wurde durch Umsetzung von Re(NO)(OH)3 = H2O mit Oxalsäure in wäßrigem Medium erhalten. Die K+-, NH4+- und Pb2+-Salze der Säure wurden isoliert sowie nichtelektrolytische Diimino-Derivate, Re(NO)(C2O4)X = L (X = 1, 10-Phenanthrolin-2,2′-Dipyridyl; L = OH-, Cl-) synthetisiert. Die Komplexe werden elementaranalytisch, spektroskopisch (UV-VIS, IR), magnetisch und durch Leitfähigkeitsdaten charakterisiert und ihre Strukturen vorgeschlagen.
    Notes: The free acid, H[Re(NO)(C2O4)(OH)2(H2O)] has been prepared from the reaction of Re(NO)(OH)3 = H2O with oxalic acid in aqueous medium. The K+, NH4+ and Pb2+ salts of the acid have been isolated. Nonelectrolytic diimino derivatives, Re(NO)(C2O4)X · L (X = 1, 10-phenanthroline, 2,2′-dipyridyl; L = OH-, Cl-) have been synthesized. The complexes have been characterised through elemental analyses, spectral (u.v., vis., i.r.) properties, magnetic and conductance data and their structures are proposed.
