Triorganotin(IV) hydrides and cyclopentadienides as well as hexaorganodistannanes containing the moiety LCN (2-(N,N-dimethylaminomethyl)phenyl-) as chelating ligand and phenyl, n-butyl or t-butyl substituents were prepared and characterized by NMR and XRD. The compounds reveal trigonal bipyramidal geometry around the central tin atom except for the distannanes in which the tin atom has tetrahedral configuration. The di-n-butyl distannane cannot be oxidized by oxygen or heavier chalcogens and give no tin radical when irradiated by UV light or treated with the TEMPO – free radical at room temperature. LCN(t-Bu)2SnH undergoes reaction in solution toward the corresponding distannane. The hydrostannation reaction of LCN(n-Bu)2SnH with ferrocenylacetylene was investigated. The CO2 activation by LCN(n-Bu)2SnH was also examined.
