Abstract

protonated tpphz ligand, H 2 tpphz · 2 H 2 O · 2 Cl, 1 , and novel 1-D coordination polymer of the type [Ni 2 (μ 2 -tpphz)(μ 2 -tp)(H 2 O) 6 ] n · (tp) · 3.65(H 2 O), 2 (where tpphz = tetrapyrido[3,2- a :2′,3′- c :3′′,2′′- h :2′′′,3′′′ -j ]phenazine, and H 2 tp = terephthalic acid) have been synthesized and characterized by single crystal X-ray diffraction analysis. The asymmetric units in both structures consist of half of their formula. In the crystal structure 1 , different types of hydrogen bonds together with π—π stacking are dominant. In the structure of 2 , Ni(II) ion is coordinated by two N atoms from tpphz, one oxygen atoms from terephthalic acid and three water oxygen atoms in a distorted meridional octahedral geometry. Each tp ligand bridges two Ni(II) centers through monodentate carboxylate group. In the overall structure of 2 , the Ni(II) centers are connected by tp and tpphz ligands to create a 1-D wave-like chain with a period of 20.91 Å running parallel down [1, 2].
