Synthesis and structural characterisation of two Mn(II) complexes with 2,4,6-tris(2-pyridyl)-l ,3,5 -triazine ligand: Effect of weak interactions in their packing diagrams

Abstract

Two neutral monomeric complexes of [Mn(tptz)(NO₃)(Cl)(H₂O)]· 0.5 H₂O 1, Mn(tptz) (NCS)₂(H₂O)] 2 {tptz = 2,4,6-tris(2-pyridyl)- 1,3,5-triazine} have been synthesized and structurally characterized by single crystal X -ray diffraction and spectroscopic study. The structural analysis reveals that the nitrate anion is linked to Mn(II) as bidentate ligand in <b>1</b> and two thiocyanate anions are linked to metal ion through N-atoms in <b>2</b>. The monomeric species of complexes <b>1 </b>and 2 undergo H-bonding resulting in supramolecular 1D and 2D architectures respectively.
