Abstract
The stannides Sm6Pd10–xSn11 and Sm3Pd5–xSn5 were synthesized from the elements by arc-melting. They were studied by powder and single-crystal X-ray data: C2/m, a = 1720.45(10), b = 451.97(2), c = 1420.60(8), β = 99.705(5)°, wR2 = 0.086, 2076 F2 values, 83 variables for Sm3Pd4.95(1)Sn5 and C2/m, a = 1738.68(7), b = 451.49(1), c = 1692.68(7), β = 121.375(3)°, wR2 = 0.0335, 2164 F2 values, 85 variables for Sm6Pd9.82(1)Sn11. Both structures show small defects for one palladium site. The palladium and tin atoms in Sm6Pd10–xSn11 and Sm3Pd5–xSn5 build up complex three-dimensional polyanionic networks in which the samarium atoms fill cavities within distorted pentagonal channels. In addition to strong covalent Pd–Sn bonding, the polyanions are further stabilized by Pd–Pd and Sn–Sn bonding.
