In‐Cage Interactions in the Clathrate Superconductor Sr(8)Si(46)

The clathrate I superconductor Sr(8)Si(46) is obtained under high‐pressure high‐temperature conditions, at 5 GPa and temperatures in the range of 1273 to 1373 K. At ambient pressure, the compound decomposes upon heating at T=796(5) K into Si and SrSi(2). The crystal structure of the clathrate is iso...

description The clathrate I superconductor Sr(8)Si(46) is obtained under high‐pressure high‐temperature conditions, at 5 GPa and temperatures in the range of 1273 to 1373 K. At ambient pressure, the compound decomposes upon heating at T=796(5) K into Si and SrSi(2). The crystal structure of the clathrate is isotypic to that of Na(8)Si(46). Chemical bonding analysis reveals conventional covalent bonding within the silicon network as well as additional multi‐atomic interactions between Sr and Si within the framework cages. Physical measurements indicate a bulk BCS type II superconducting state below T (c)=3.8(3) K.
