Abstract:
The stannide Sm 2 Rh 3 Sn 5 was obtained by arc-melting of the elements and subsequent annealing at 1070 K in a silica tube. Sm 2 Rh 3 Sn 5 crystallizes with the orthorhombic Y 2 Rh 3 Sn 5 type structure, space group Cmc 2 1 , Z =4: a =444.46(8), b =2636.2(4), c =718.3(1) pm, wR =0.0711, 1761 F 2 values and 61 variables. The three crystallographically independent rhodium atoms show tricapped trigonal prismatic coordination by samarium and tin atoms. Sm 2 Rh 3 Sn 5 can be considered as a simple 1:1 intergrowth structure of TiNiSi- and NdRh 2 Sn 4 -related slabs of compositions SmRhSn and SmRh 2 Sn 4 . Temperature dependent magnetic susceptibility data revealed van Vleck type behavior caused by the proximity of the exited 6 H 7/2 state to the 6 H 5/2 ground state of Sm 3+ , and an antiferromagnetic ordering occurs at T N =3.5(5) K.
