The new pseudo-binary intermetallic compound, Ti11(Sb, Sn)8, has been synthesized by reacting Ti and Sb in a Sn flux at 1100°C and its structure determined from both single-crystal X-ray and neutron diffraction data (orthorhombic, Pnma, Z = 4, X-ray diffraction at 90 K: a = 14.6877(6) Å, b = 5.5677(2) Å, c = 17.7207(7) Å, V= 1449.14(10) Å3, neutron diffraction at room temperature: a = 14.677(6) Å, b = 5,577(3) Å, c = 17.716(6) Å, V= 1450(1) Å3). The structure contains two differently oriented repeating layers and interstitial atoms that are closely connected to make linear chains aligned along the crystal b axis. The compound exhibits mixed site occupancies of Sb and Sn on the anion sites. The phase width (Sb/Sn ratio = 0.98-1.40) was determined by microprobe elemental analysis. The electrical resistivity of a single crystal as a function of temperature is anisotropic (ρ//b=1 ∼ 2×10-1 mΩ·cm, ρ⊥b = 0.5×10-1 mΩ·cm) and confirms that this compound is metallic. Magnetic susceptibility measurements show Pauli paramagnetism.
