dc.description.abstractEnA novel two-dimensional (2D) coordination polymer with the formula Cr(pyrazine)2(OSO2CH3)2 has been synthesized and characterized. Powder X-ray diffraction data reveal that this material, which crystalizes in the Pnnm orthorhombic space group, is composed of rectangular grid layers with octahedral CrN4O2 nodes and pyrazine vertices. Since the redox-active pyrazine ligand can be reduced in the presence of transition metals, X-ray absorption spectroscopy and quantum chemical calculations were used to confirm the +II oxidation state of the Cr center. Magnetic susceptibility measurements indicate the presence of antiferromagnetic interactions between the chromium(II) centers through the neutral pyrazine and suggest an antiferromagnetic ordered state below TN ≈ 10 K, which was confirmed by heat-capacity measurements.
