“…While these studies met with no more success in the preparation of coordination complexes of Tc(IV), they did yield important confirmation of literature reports that these reductants can under certain conditions generate metal nitride species (Chatt 1969). We have verified this by confirming isolation of a Tc(V) nitride complex by reduction of pertechnetate by hydrazine in the presence of dithiocarbamate as a complexing ligand (Baldas 1986).…”

“…Exclusion of moisture in the ethanol solution was identified as a necessary condition to isolate a ReOCl,(PPh,), complex, since the nitride ReNCl,(PPh,), was obtained when the ethanol was wet. In fact, these methods are very similar to those leading to the nitride (8,9).…”

“…It was obtained when hydrazinium dihydrochloride was reacted with HReO, in dry ethanolHCl, thorough drying being achieved by distilling out H,O via the benzene-ethanol-water azeotrope. This same material was later obtained when Chatt et al (8) reacted yellow ReOCl,(PPh,), or ReO(OEt)Cl,(PPh,), with hydrazinium hydrochloride in dry ethanol or THF. Exclusion of moisture in the ethanol solution was identified as a necessary condition to isolate a ReOCl,(PPh,), complex, since the nitride ReNCl,(PPh,), was obtained when the ethanol was wet.…”

“…The products obtained by these methods correspond to the compound studied by Chatt and Rowe (4) and to "isomer" I of Johnson et al (3, but its stereochemistry is not explicitly identified. Hence, although the existence of stereoisomers for ReOC13(PPh3), has been mentioned (5,6,8), this '~u t h o r to whom correspondence may be addressed. '~h r o u~h o u t this paper, the term "isomer" will be used strictly to refer to these three materials described by Wilkinson and coworkers.…”

The various preparative procedures described in the literature for ReOCl,(PPh,), were rep~ated. The standard methods were found to yield a yellow triclinic material ( P l , a = 11.793, b = 14.300, c = 16.422 A, a = 64.04", P = 84.31°, y = 87.32", R = 0.064). The unit cell contains three discrete monomeric molecules with the trans-bis(phosphine) configuration, one of which has its C1-Re=O unit disordered over two opposite directions. Recrystallization in CH2C1, yielded crystals of the bright green monoclinic polymorph (C2/c, a = 24.347, b = 9.604, c = 15.666 A, P = 1 16.77", R = 0.025) containing the same monomeric molecule, but with a different conformation of the PPh, ligands and a different packing pattern. These two polymorphs actually correspond to "isomers" 1 and 2 described by Johnson, Lock, and Wilkinson in 1964. Attempts to prepare their third "isomer" yielded powders containing ReOC13(PPh3)2 (green polymorph) and ReNC1,(PPh3)2. The IR and ,'P NMR spectra of these samples are discussed. ANNE-MARIE LEBUIS et

Abstract Rhenium(VII) nitride chloride, ReNCl4, is prepared by the reaction of ReCl5 with nitrogen trichloride. It forms metallic glazing, hygroscopic needles with an effective magnetic moment of 0.23 B.M. In the mass spectrum only the molecular ion ReNCl4⊕ is present, followed by ReNCl3⊕. The crystal structure was determined by X-ray diffraction methods (space group Il, 265 independent reflexions, R = 0.071). The structure consists of ReNCl4 units, which are linked by strongly alternated Re ≡ N-Re chains with different bond lengths of r Re ≡ N = 158 pm and r Re-N = 248 pm. The structure is very similar to that of WOCl4.
