The present manuscript is dealing with chemical bonding and Mossbauer spectroscopic investigations on the coinage-metal polyphosphides AgSbP14, [Ag3Sn]P-7 and [Au3Sn]P-7. Sb(Ill) has been identified in the HgPbP14-type compound AgSbP14 by Mossbauer spectroscopic experiments, representing the first P-14-polyphosphide with the cation combination M+(Ag)/M'(3+)(Sb). A combined spectroscopic and theoretical approach using various methods is applied to semi-conducting [Ag3Sn]P-7 and [Au3Sn]P-7 to characterize the metalloid [M3Sn] clusters coordinated to the P-network. Sn-5s electron densities, electric field gradients and effective charges were calculated by DFT methods and are discussed in relation to the Mossbauer data. (c) 2008 Elsevier Masson SAS.
