Ag2PdP2O7

Abstract

Disilver(I) palladium(II) diphosphate, Ag2PdP2O7, is isotypic with Na2PdP2O7. It consists of infinite diphosphato-palladate(II) [Pd(P2O7)2/2]2− ribbons with the PdII ion in an almost square-planar coordination (overline1 symmetry) and the P2O7 group exhibiting 2 symmetry. The [Pd(P2O7)2/2]2− ribbons are linked by distorted [AgO6] octahedra. 31P-MAS NMR studies on Ag2PdP2O7 are in accordance with one independent site for phosphorus; its isotropic chemical shift δiso = 21.5 p.p.m. is similar to that of Pd2P2O7.
