Abstract

A novel nano – sized  manganese (II) coordination polymer, [{Mn(NCS)₂(L)(H₂O)₂}(L)]_n  , (1) (L^- = 4,4'-Bipyridine), have been synthesized by a sonochemical process and characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), IR spectroscopy and elemental analysis.  Direct calcination of the single crystals and nano-sized compound 1 at 400 ⁰C under air atmosphere yields mixture of K₂Mn₂ (SO₄)₃, MnOS and Mn₃O₄ nanoparticles. Results show that the size and morphology of the K₂Mn₂ (SO₄)₃, MnOS, Mn₃O₄ nanoparticles depend on the particles size of compound 1. Decrease in the particles size of compound 1 leads to decrease in the particles size of the K₂Mn₂ (SO₄)₃, MnOS and Mn₃O₄.
