    • The structure BT3 is similar to the one reported by Lee (Ref.). The putative structures of configuration BT3 collapsed to BT2 configuration upon standard and CP-corrected gradient optimizations at the MP2/6-31 G level. We could not obtain structure BT3 at the MP2/aug- (d,p) -6-311 G level using standard optimization procedure since the putative structures collapsed to parallel displaced configuration.
