Notes:
The structure of 2,4,6-tri-tert-butyl-1,3,5-triphosphabenzene (1) as well as the He(I) photoelectron spectra of 1 and 2,4-di-tert-butyl-1,3-diphosphabenzene (2) have been investigated. It was found that 1 is planar with average C-P-C angles of 109.3° (±0.3°) and P-C-P angles of 130.7° (± 0.4°). All P-C bond lengths amount to 1.727 (± 0.008) Å. The PE spectra were interpreted by comparison with the results of ab initio calculations (RHF/ 6-31G*). They reveal a splitting of the lone pairs on P in 2 of 0.7 eV.
