The silicides ScIr 4 Si 2  and  RE Rh 4 Si 2  ( RE =Sc, Y, Tb-Lu) and silicide stannides  RE Rh 4 Si 2– x  Sn  x   ( RE =Y, Nd, Sm, Gd-Lu) were synthesized from the elements by arc-melting and subsequent annealing. The new compounds crystallize with the orthorhombic YRh 4 Ge 2  type structure, space group  Pnma . They were characterized by X-ray powder patterns and several structures were refined from single crystal X-ray diffractometer data. The main structural motifs of this series of silicides are tricapped trigonal prisms formed by the transition metal and rare earth atoms. One of the two crystallographically independent silicon sites allows for formation of solid solutions with tin, exemplarily studied for ErRh 4 Si 2– x  Sn  x  . Electronic structure calculations reveal strong covalent Rh–Si bonding as the main stability factor. Multinuclear ( 29 Si,  45 Sc, and  89 Y) magic-angle spinning (MAS) NMR spectra of the structure representatives with diamagnetic rare-earth elements (Sc, Y, Lu) are found to be consistent with the crystallographic data and specifically confirm the selective substitution of Sn in the Si2 sites in the quaternary compounds YRh 4 SiSn and LuRh 4 SiSn.
