A new double perovskite Pr₂CoTiO₆ has been synthesized by conventional solid state method. The structure of the compound has been investigated through powder x-ray and neutron diffraction techniques. The Rietveld refinement of the structural data shows that the compound crystallizes in the monoclinic structure (S.G. P2₁/n # 14)). The refined cell parameters are: a = 5.4800(6) Å, b = 5.6221(6) Å, c = 7.7700(9) Å, β = 89.98(4)°. Monoclinic distortion Ï• associated with the distortion of the CoO₆- and TiO₆- octahedra is 13.7°. Magnetic measurements down to 4 K show antiferromagnetic-like ordering of the material, TN ~ 17 K with paramagnetic effective magnetic moment μ_eff = 6.92_μB. At room temperature, the dielectric constant and dielectric loss of Pr₂CoTiO₆ are 45.5 and 1.2 respectively.
