StructureD 2000 Structure, Chemical Bonding and 119Moessbauer Spectroscopy of LaRhSn and

CeRhSn. — The title compounds are characterized by single crystal XRD, 119Sn Moessbauer spectroscopy, and DFT band structure calculations. They crystallize with the ZrNiAl-type structure in the space group P62m with Z = 3. The structures contain two crystallographically different Rh sites which both have a tricapped trigonal pris-matic coordination. Together the Rh and Sn atoms build up three-dimensional [RhSn] networks in which the rare earth atoms fill distorted hexagonal channels. — (SCHMIDT, T.; JOHRENDT, D.; SEBASTIAN, C.
