| Popis: | Hydrothermal reactions of Mn(CH3COO)(2)center dot 4H(2)O and 2,2-dimethylglutaric acid (H(2)dmg) in the presence of pyridyl group ligands (4,4'-bipyridine (bipy) or 1,2-di(4-pyridyl)ethylene (dpeten)) are produced under the same conditional. Two new three dimensional coordination polymers, namely, [Mn-2(mu(4)-dmg)-(mu(4)-dmg)(mu-bipy)](n), (1), and [Mn-2(mu(4)-dmg)(mu(4)-dmg)(mu-dpeten)](n) (2), were characterized by IR spectroscopy, elemental analysis, single crystal and powder X-ray diffractions as well as thermal analysis techniques. The X-ray single crystal data exhibits that 1 displays 3D framework without interpenetrating, whereas 2 shows a 2-fold 3D -> 3D interpenetrating structure. The dmg anions coordinate to Mn(II) ions as a chelate and bis-bridging ligand to form 1D chain. The adjacent 1D chains are connected by bipy or dpeten ligands to generate 3D frameworks. Additionally, the dmg ligand exhibits two unprecedented coordination modes. (C) 2019 Elsevier Ltd. All rights reserved. |
