摘要：

CdCl2 dissociates in dimethylformamide into the species Cd(DMF)62+,CdCl(DMF)5+ and CdCl3- as determined by ll3CdNMR spectroscopy. 11B and ll3Cd NMR spectra of MBH4/CdCl2 solutions in this solvent show the presence of complexes [CdCl2_η(BH4)η+1]- with rapid exchange of BH4- and Cl- at ambient temperature. There is no evidence that Cd(BH4)2 is formed in a metathetical reaction. The crystal structure of CdCl2·2DMF has been determined. It is a coordination polymer containing hexacoordinated Cd atoms with the DMF molecules in cis-position. Coordination of DM F occurs via the carbonyl oxygen atoms. © 1990, Walter de Gruyter.
