Syntheses, structures and properties of seven H2BTA coordinating 3-D metallic complexes containing 0-, 1-, 2-, and 3-D frameworks (H2BTA = bis(tetrazolyl)amine)

Abstract

Seven 3-D metallic complexes coordinated and controlled by the deprotonated anions of H₂BTA ligand (H₂BTA = bis(tetrazolyl)amine): a 0-D compound of Co(HBTA)₃·4.5H₂O (1), two 1-D compounds of Cu(BTA)(H₂O)₂ (2) and Mn₄(BTA)₄(H₂O)₁₂·2H₂O (3), a 2-D compounds [Mn₇(BTA)₆(OH)₂(H₂O)₁₂] (4) and three 3-D compounds containing two isomorphous complexes of [Mn(BTA)₂Na₂(H₂O)₂] (5) and [Co(BTA)₂Na₂(H₂O)₂] (6) as well as Mn(BTA)(H₂O) (7) have been synthesized under different synthetic conditions and characterized by single crystal X-ray diffraction analysis. In 1–7, the deprotonated anions of the H₂BTA ligand control the different crystal structures using not only the different coordinations to transition metal ions as several different multidentate ligands but simultaneously the formation of complementary intermolecular hydrogen bonds.
