Abstract
We have discovered a series of novel pentacarbonylchromium derivatives of bismuth from the reactions of NaBiO3 with [Cr(CO)6] in KOH/MeOH solutions. When the reaction was carried out at room temperature, the highly charged [Bi{Cr(CO)5}4]3- (1) was obtained, whose structure was shown by X-ray analysis to possess a central bismuth atom tetrahedrally coordinated to four [Cr(CO)5] groups. As the reaction was heated at 80°C, the methyl-substituted complex [MeBi{Cr(CO)5}3]2-(2) was obtained, presumably via the C-O activation of MeOH. Further reactions of 1 with CH2Cl2 or CH≡CCH2Br form the halo-substituted complexes [XBi{Cr(CO)5}3]2-(X = Cl, 3; Br, 4), respectively. On the other hand, the reactions of 1 with RI (R = Me, Et) led to the formation of the alkyl-substituted complexes [RBi{Cr(CO)5}3]2-(R = Me, 2; Et). The formation of complexes 1-4 is discussed, presumably via the intermediate bismuthinidene [Bi{Cr(CO)5}3]- or the trianion [Bi{Cr(CO)5}3]3-.
