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.

Some new complexes of rhenium containing monocoordinating acetylacetone viz. [Re(NO)(acac)2(Cl)H2O], Re(NO)(acac)3(acacH)(H2O)2 have been synthesized by reacting acetylacetone with either Re(NO)Cl3 · H2O or Re(NO)(OH)3 · H2O. The preparation of [Re(NO)(py)(acac)2(Cl) · H2O], [Re(NO)(acac)(OH)(Cl) · H2O], [Re2(NO)2(acacH)3(acac)2 · Cl4], [Re(NO)(acac)2(OH) · H2O] · 2 H2O have also been described. These complexes were characterized through their elemental analyses, u.v., vis, i.r., 1Hn.m.r., magnetic, and conductance data. Copyright © 1987 Verlag GmbH &amp; Co. KGaA, Weinheim

Nitrosyl rhenium complexes: Syntheses, properties, and structures of acetylacetonato derivatives

Reaction of Re(NO)Cl3 with bases have been studied under different experimental conditions. Formation of Re(H2O)(NO)(OH)3 have been demonstrated and the ultimate product with excess base has been isolated as Tl[Re(NO)(OH)4]. Their i. r. spectral data has been analysed and properties described. Copyright © 1978 Verlag GmbH &amp; Co. KGaA, Weinheim

Nitrosorhenium complexes: Studies on Nitrosotrihydroxo Rhenium

Hydrated nitrosotrichlororhenium, Re(NO)Cl3 · sH2O cannot be desiccated to the anhydrous product. Hydrogen chloride is expelled and [Re(H2O)(NO)(OH)Cl2] and [Re(H2O)0.5(NO) (OH)2Cl] are produced depending on the conditions of the reactions. Potentiometric studies have indicated that in aqueous ethanolic solutions, the trichloro complex rapidly liberates two equivalents of hydrogen ions while the release of chloride ions are time dependent. Two equivalents of chloride ions are, however, present in a equilibrium system. The third chlorine atom is rigidly bound to the rhenium atom. A chloride bridged structure has been proposed.

Studies on the Hydrolysis of Nitrosotrichlororhenium

The first stable series of fluoronitroso complexes have been prepared with rhenium. These include M2[Re(NO)F5] (M = K, Cs), Re(NO)LF3 (L = dipy, phen), Re(H2O)2(NO) (OH)F2, Re(H2O)2(NO) (OH)2F and a cationic species [Re(dipy)2(NO)F]PtCl6. These are characterized by their analytical, magnetic, conductance and i.r. spectral data. © 1977.

Fluoronitroso complexes of rhenium

Re(NO)Br3 has been prepared by different methods. The anionic [Re(NO)Br5]-2 has been isolated as salts of Cs+, Rb4 , (pyH)+ and LH+ (L stands for 1,10-phenanthroline and 2,2'-dipyridyl ions. The non-electrolytic [Re(NO)Br3L] and cationic [Re(NO)(phen)2Br]ptCl6 have also been prepared. Measurement of electronic and i.r. spectra and magnetic moments have been carried out.

Bromonitrosyl complexes of rhenium

Nitric oxide reacts with hydrated ReO2 in aqueous suspension at 70–80°C to produce quantitatively Re(NO)(OH)3, ReO 4− and NH 4+. [Re(NO)Cl5]2− and ReO 4− are produced in stoichiometric quantities by the reaction of either NO with ReO2 suspension in 6 N HCl or by the action of a mixture of NO and HCl with an aqueous ethanolic or aqueous suspension of ReO2 at 70–80°C. Passage of NO over 1,10‐phenanthrolinium hexahalorhenate(IV) at 220°C produces nitrosyl halide, hydrogen halide and [Re(NO) (phen)Cl3] or [Re(NO)(phen)Br3]. Copyright © 1973 Verlag GmbH &amp; Co.
