The nitrosylcarbonylisonitrile complexes η5-C5H5M(NO)(CO)CNR (R = Me for Cr, Mo, W; R = Et, SiMe3, GeMe3, SnMe3 for Mo) are formed by treatment of the nitrosylcarbonylcyanometalates Na[η5-C5H5M(NO)(CO)CN] with [R3O]BF4 (R = Me, Et), Me3SiCl, Me3GeCl or Me3SnCl. The isoelectronic dicarbonylisonitrile compounds η5-C5H5Mn(CO)2CNR (R = SiMe3, GeMe3, SnMe3, PPh2, AsMe2) and η5-C5H5Re(CO)2CNAsMe2 are obtained by analogous reactions of Na[η5-C5H5M(CO)2CN] (M = Mn, Re) with Me3ECl (E = Si, Ge, Sn), Ph2PCl and Me2AsBr.With phosgene the anionic complexes Na[η5-C5H5M(CO)2CN] (M = Mn, Re) can be transformed into the new carbonyldiisocyanide-bridged dinuclear complexes η5-C5H5M(CO)2CN-C(O)-NC(OC)2M-η5-C5H5. Finally, the reactions of η5-C5H5M(NO)(CO)CNMe (M = Cr, Mo, W) with NOPF6, leading to the cationic dinitrosylisonitrile complexes [η5-C5H5M(NO)2CNMe]+, are described.  相似文献
