The polarity of XH and XM bonds in compounds of the ArXH and ArXM (X = O, S, NR; M = Hg, Sn, Pb, Sb) types and their capacity for coordination and dissociation

The importance of the transannular secon

The importance of the transannular secondary bonding strength in the molecular structures of metallocanes of type [X(CH2CH2Y)2MRR′] and [X(CH2CH2Y)2M′R] (M = Ge(IV), Sn(IV), Pb(IV), M′ = As(III), Sb(III) and Bi(III); X = NR″, O, S; Y = O, S)

The conformation adopted by the metallocane ring has exhibited various conformations along with the extreme conformations boat-boat, boat-chair and chair-chair. The structural diversity observed in these eight-membered rings results in a variety of coordination numbers, as well as in the presence of
