Nature of the heavy formal double bonds AsCh, SbCh and BiCh (Ch = S, Se, Te) in NCN-pincer supported arsinidene, stibinidene and bismuthinidene chalcogenides
The synthesis of arylpnictinidenes 2,6-(Ph<sub>2</sub>PNMes)<sub>2</sub>C<sub>6</sub>H<sub>3</sub>Pn based upon a novel bis(phosphine imine) NCN-pincer ligand is reported (Pn = As, Sb, Bi). The oxidation of 2,6-(Ph<sub>2</sub>PNMes)<sub>2</sub>C<sub>6</sub>H<sub>3</sub>Pn with sulfur, selenium and tellurium, respectively, afforded arylarsinidene chalcogenides 2,6-(Ph<sub>2</sub>PNMes)<sub>2</sub>C<sub>6</sub>H<sub>3</sub>AsCh, arylstibinidene chalcogenides 2,6-(Ph<sub>2</sub>PNMes)<sub>2</sub>C<sub>6</sub>H<sub>3</sub>SbCh and arylbismuthinidene chalcogenides 2,6-(Ph<sub>2</sub>PNMes)<sub>2</sub>C<sub>6</sub>H<sub>3</sub>BiCh, which can be formulated as containing terminal As[double bond, length as m-dash]Ch, Sb[double bond, length as m-dash]Ch and Bi[double bond, length as m-dash]Ch double bonds. Based on the complementary bonding analysis, the bonding situation is best described in terms of bipolar <sup>+</sup>Pn-Ch<sup>-</sup> single bonds (Ch = S, Se, Te).
