Abstract

Abstract : Solvothermal reactions of a novel multidentate ligand, 2, 5-bis-(1, 2, 4-triazol-1-yl)-terephthalic acid (H2 TTPA), with MnCl2 afforded three structurally distinct coordination polymers with the same formula, [Mn(TTPA)·H2 O] n (Mn- (1–3 )). Abstract : Solvothermal reactions of a novel multidentate ligand, 2, 5-bis-(1, 2, 4-triazol-1-yl)-terephthalic acid (H2 TTPA), with MnCl2 afforded three structurally distinct coordination polymers with the same formula, [Mn(TTPA)·H2 O] n (Mn- (1–3 )). Single-crystal X-ray diffraction analyses show that complex Mn- 1 exhibits a binodal 3D framework with Schläfli symbol {4 2 ·6·8 3 }, while Mn- 2 displays a trinodal 3D framework with point symbol {4 16 ·6 12 }{4 4 ·6 2 }2 . Mn- 3 shows a novel complicated topology, which is characterized as a 4, 5, 6-c net 3D framework. Further magnetic analysis discloses the antiferromagnetic (AF) behavior between Mn(ii ) ions in complexes Mn- 2 and Mn- 3 .
