Abstract
The contradictions in the literature concerning the aromaticity of lam bda5-lambda5-lambda5-1,3,5-triphosphabenzene have been resolved by car rying out geometry optimized Mp2/6-31G ab initio calculations for lam bda5-lambda5-lambda5-1,3,5-triphosphabenzene and lambda5-lambda5-1,3-d iphosphacyclobutadiene. The possible problems when using Bird's aromat icity index as a sole measure of aromaticity have been pointed out.
