Title: Structural, dielectric and magnetic studies on BiPbSr{sub 2}MnO{sub 6}

We have investigated structural, room temperature dielectric and magnetic properties of BiPbSr{sub 2}MnO{sub 6} as a potential candidate to show magnetoelectric coupling. The X-ray diffraction study shows the crystal structure is noncentrosymmetrical with orthorhombic space group A2aa while neutron diffraction study demonstrates the above structure is centrosymmetrical with orthorhombic space group Amaa. The DC susceptibility measurement performed on polycrystalline powders exhibits antiferromagnetic ordering below transition temperature ∼ 190K. The frequency dependent dielectric measurement at room temperature displays the normal polar dielectric behavior.
