Tetrel-Bond Interactions Involving Metallylenes TH₂ (T = Si, Ge, Sn, Pb): Dual Binding Behavior.

ABSTRACT: The dual binding behavior of the metallylenes TH₂ (T = Si, Ge, Sn, Pb) with some selected Lewis acids (T'H₃F, T' = Si, Ge, Sn, Pb) and bases (N₂, HCN, CO, and C₆H₆) has been investigated by using the high-level quantum chemical method. Two types (type-A and type-B) of tetrel-bonded complexes can be formed for TH₂ due to their ambiphilic character. TH₂ act as Lewis bases in type-A complexes, and they act as Lewis acids in type-B ones. CO exhibits two binding modes in the type-B complexes, one of which is TH₂···CO and the other is TH₂···OC. The TH₂···OC complexes possess a weaker binding strength than the other type-B complexes. The TH₂···OC complexes are referred to as th
