Novel semiconducting metal-organic framework: Synthesis, structural characterisation and electrical conductivity studies of manganese based two dimensional coordination polymer

New Manganese(II) dichloro and pyrazine bridged coordination polymer containing rectangular framework [Mn(mu-pz)(mu-Cl)(2)](n) was synthesised and structurally characterised. Single crystal X-ray structure of the coordination polymer [Mn(mu-pz)(mu-Cl)(2)](n) displayed 2D rectangular framework with infinite sheet structure. Thermogravimetric analysis showed that the [Mn(mu-pz)(mu-Cl)(2)](n) coordination polymer is stable and robust up to 310 degrees C. Electrical conductivity measurements of [Mn(mu-Pz)(mu-Cl)(2)](n) were carried out as a function of frequency at various temperatures and the coordination polymer exhibited semiconducting property with activation energy E-a = 0.70 (+/- 0.03) eV.
