Materials Data on Sr(SiPd)6 by Materials Project
Sr(PdSi)6 crystallizes in the orthorhombic Ibam space group. The structure is three-dimensional and consists of four strontium molecules and one PdSi framework. In the PdSi framework, there are two inequivalent Pd+2.33+ sites. In the first Pd+2.33+ site, Pd+2.33+ is bonded in a 5-coordinate geometry to five Si+2.67- atoms. There are a spread of Pd–Si bond distances ranging from 2.45–2.62 Å. In the second Pd+2.33+ site, Pd+2.33+ is bonded in a 7-coordinate geometry to seven Si+2.67- atoms. There are a spread of Pd–Si bond distances ranging from 2.44–2.98 Å. There are two inequivalent Si+2.67- sites. In the first Si+2.67- site, Si+2.67- is bonded in a 5-coordinate geometry to six Pd+2.33+ atoms. In the second Si+2.67- site, Si+2.67- is bonded in a 4-coordinate geometry to five Pd+2.33+ atoms.
