A One-Dimensional Manganese(II) Coordination Polymer Derived from Zerovalent Manganese and 1-Hydroxybenzotriazole − Synthesis, Characterization, Crystal Structure and Magnetic Properties

The reaction of zerovalent manganese with 1-hydroxybenzotriazole, btaOH, and NH4SCN in DMF in the presence of dioxygen allows isolation of the one-dimensional coordination polymer [Mn3(btaO)2(NCS)4(DMF)8]n (3). X-ray diffraction analysis reveals that the chain is best described as [Mn2(btaO)2(NCS)2(DMF)6] dimers linked by Mn(NCS)2(DMF)2 bridges. Molar magnetic susceptibility measurements of 3 in the 5−300 K range indicate weak antiferromagnetic coupling between the MnII atoms within the dinuclear subunits of the chain.
