Hydrothermal In Situ Synthesis of a Novel Three-dimensional Tetrazole Coordination Polymer with Manganese Ions

The hydrothermal reaction of benzotriazol-1-yl-acetonitrile and Mn(ClO4)(2)center dot 6H(2)O in the presence of NaN3 yielded almost colorless block-shaped crystals of a novel three-dimensional manganese coordination compound with benzotriazol-1-yl-acetic acid and 1-(1H-tetrazol-5-ylmethyl)-1H-benzotriazole ligands, which were obtained by in situ hydrolysis and 2+3 cyclo-additional reactions of the cyano group in Pyrex tube at 150 degrees C. In this compound azide, benzotriazol-1-yl-acetic acid, and 1-(1H-tetrazol-5-ylmethyl)-1H-benzotriazole as multidentate ligands coordinate to three crystallographically independent manganese atoms to form a novel three-dimensional coordination polymer. Dielectric measurements show no dielectric anomaly within the temperature range of 120 K to 300 K.
