Abstract

The complex perovskite (SrLa)(MgMo)O₆ has been prepared at 1 350°C under a flowing nitrogen atmosphere. The crystal system is cubic with a unit cell parameter of a₀ = 7.932(1) Å. The i.r. spectrum shows two strong absorption bands at 606 and 380 cm^-1, respectively, which are due to ²T_1u modes of molybdenum octahedra MoO₆ in the crystal lattice. The compound shows paramagnetic behaviour following the Curie-Weiss law below room temperature with an effective magnetic moment of 1.72(1) μ_B, which is consistent with that of the spin-only value (1.73 μ_B) for Mo⁵⁺ (4d¹ electronic configuration).
