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.
