Abstract

Potassium Manganese Nickel Sulphate Hexahydrate (KMNSH) crystals have been successfully grown by using traditional slow evaporation method. The empirical formula of KMNNSH is K2Mn_0.1Ni_0.9 (SO₄)₂?6H₂O with formula weight 430.7698. KMNNSH crystal revealed monoclinic space group P2(1)/c, a = 6.12(4) ?, b = 12.19(9) ?, c = 8.96(7) ?, α = γ = 90?, β = 105.3(2), V = 645(1)?3, Z = 2, Dc = 2.2281 g/cm3 with deep green color. IR confirms that there is strong interaction between free water molecules. The thermal analysis indicates that the water molecules are present in the KMNNSH crystals. The transmission spectrometry of KMNNSH in the range from UV to near IR wavelengths is reported. Atomic Absorption Spectroscopy also have been studied and discussed.
