摘要

The reaction of stibinidene and bismuthinidene ArM [where Ar=C6H3-2,6-(CH=NtBu)(2); M=Sb (1), Bi (2)] with transition metal (TM) carbonyls Co-2(CO)(8) and Mn-2(CO)(10) produced unprecedented ionic complexes [(ArM)(2)Co(CO)(3)](+)[Co(CO)(4)](-) and [(ArM)(2)Mn(CO)(4)](+)[Mn(CO)(5)](-) [where M=Sb (3, 5), Bi (4, 6)]. The pnictinidenes 1 and 2 behaved as two-electron donors in this set of compounds. Besides the M -> TM bonds, the topological analysis also revealed a number of secondary interactions contributing to the stabilization of cationic parts of titled complexes.
