We have investigated the core level and photoinduced Pb Auger transition regions of Pb[sub 2]P[sub 2]S[sub 6], a member of the M[sub 2]P[sub 2]X[sub 6] chalcogenophosphate family using the x-ray photoemission spectroscopy. The XPS core level spectra show single peak structures for the Pb, P and S core levels in agreement with crystallographic data. The combined analysis of the Pb4f[sub 7/2] core level and the PbN[sub 6]O[sub 45]O[sub 45] Auger transition has allowed us to deduce the modified Auger parameter for Pb in Pb[sub 2]P[sub 2]S[sub 6] obtaining in this way information on the Pb-S bond in this compound. © 2000 American Institute of Physics.
