Materials Data on Ag2PdCl4 by Materials Project
PdAg2Cl4 crystallizes in the orthorhombic Cmce space group. The structure is three-dimensional. Pd2+ is bonded in a square co-planar geometry to four Cl1- atoms. There are two shorter (2.33 Å) and two longer (2.34 Å) Pd–Cl bond lengths. Ag1+ is bonded to six Cl1- atoms to form a mixture of distorted edge and corner-sharing AgCl6 octahedra. The corner-sharing octahedra tilt angles range from 7–35°. There are a spread of Ag–Cl bond distances ranging from 2.65–3.12 Å. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a distorted trigonal non-coplanar geometry to one Pd2+ and two equivalent Ag1+ atoms. In the second Cl1- site, Cl1- is bonded to one Pd2+ and four equivalent Ag1+ atoms to form a mixture of distorted edge and corner-sharing ClAg4Pd square pyramids.
