The ditetrel bond: noncovalent bond between neutral tetrel atoms
Steve Scheiner
Abstract
. The larger T atoms, whether Si, Ge, or Sn, form weaker TBs, with little dependence on their identity within this subgroup. In contrast, there is a strong dependence of the interaction energy on the size of the acidic tetrel atom, growing quickly in the order C < Si < Ge < Sn < Pb. The interaction energies correlate closely with (i) the total charge transferred, (ii) the stretch of the covalent T-F bond and (iii) the product of the extrema on the electrostatic potentials. The charge being transferred originates in the four covalent bonds of the Lewis base molecule. The systems bear striking resemblance to dihydrogen bonds where two H atoms of opposite charge attract one another.
