Structural and Magnetic Properties of the Coordination Polymer Mn(dca)2(H2O)2·2Me4pyz, dca = Dicyanamide (N(CN)2-), Me4pyz = Tetramethylpyrazine

Abstract

The structure of Mn(dca)2(H2O)2�2Me4pyz (dca = dicyanamide, N(CN)2-; Me4pyz = tetramethylpyrazine) contains one-dimensional polymeric chains of Mn(dca)2(H2O)2. The Me4pyz molecules hydrogen-bond to the water ligands, and form ���Me4pyz���H2O���Me4pyz���H2O��� chains which flank either side of the coordination polymer chains. Magnetic susceptibility studies show that very weak intra-chain antiferromagnetic-coupling occurs.
