The electronic properties of a diarsaallene ArAs=C=AsAr and a phosphaarsaallene ArP=C=AsAr (Ar: 2,4,6-tri-tert-butylphenyl) have been investigated by using UV photoelectron spectroscopy and by density functional calculations on model compounds [(CH3)2C6H 3Pn=C=AsC6H3(CH3)2, Pn: As, P]. Moreover, a comparison of the geometrical and electronic structures of the parent heteroallenes with those of the arsaethene H2C=AsH and phosphaethene H2C=PH has also been undertaken in order to determine the magnitude of the interaction between the π bond and the pnictogen lone pair nPn. © 2003 Elsevier B.V.
