Journal ArticleDOI
Radical cation-radical anion salts: Molybdenum complexes containing the [TCNQ]•− or [TCNE]•− radical anions. X-ray crystal structure of [Mo(Et2NCS2)4](TCNQ)
Marc Decoster,Françoise Conan,Jacques E. Guerchais,Y. Le Mest,J. Sala Pala,John C. Jeffery,Eric Faulques,A. Leblanc,P. Molinie +8 more
TL;DR: In this article, cyclic voltammetry and ESR studies revealed the presence for all types of complexes of the molybdenum(V) radical cation [Mo(dtc) 4 ] •− which is associated with the radical anion TCNX •− in 2 (X = Q) and 4(X = E) and with a 1:1 mixture of neutral and anionic TCNQ species in 3.
Journal ArticleDOI

TL;DR: In this article, the insertion of alkynes with low steric hindrance, and dicyanoacetylene (NCCCCN) into both MH of [(C 5 H 5 ) 2 MH 2 ] bonds are described.
Journal ArticleDOI
Transition-metal-cyanocarbon chemistry. 2. Cyanoacetylenes insertions into the metal-hydrogen bond of (.eta.5-C5H5)(CO)3MH (M = Mo, W) complexes. Formation of phosphorus ylide complexes and the structure of (.eta.5-C5H5)(CO)2Mo[.eta.2-C(CN)PPh3CHCN]
Journal ArticleDOI
Transition metal-cyanocarbon chemistry: IX. Reactions of monocyanoacetylene with dicarbonylcyclopentadienylmethylthiolatoiron(II). Crystal structures of [FeC(O)C(CN)CH(SCH3) (η5-C5H5)(CO)] and of μ-η2-Fe(CCCN)(η5-C5H5)(CO)2][Co(CO)3]2
