摘要：

The reaction of [HB(pz)3]SnCl3 (pz = 1-pyrazolyl) with [Co(CO)4]- gave a mixture of products from which the anion [trans-&{;[(CO)4Co]Cl2Sn&};2Co( CO)3]- (2) was isolated as the [Co&{;(pz)3BH&};2]+ salt, and characterised by X-ray crystallography. Reactions of [H2B(pz)2]SnCl3 with [Co(CO)4]-, and of ClSn[Co(CO)4]3 with K[HB(pz)3] or K[H2B(pz)2], were also investigated. For comparison with 2, the anion [trans-(Cl3Sn)2Co(CO)3]- (1) was made from Cl3SnCo(CO)4 and [SnCl3]- and structurally characterised as its Et4N+ salt. In both 1 and 2 the Sn-Co bonds to the central cobalt atom are remarkably short (2.444(1) and 2.468(1)Å, respectively). © 1990.
