Novel metal-organic 1-D coordination polymer based on pyrazine-2,5-dicarboxylate ligands: synthesis and structure investigation

The novel Zn(II) based complex, [Zn(pz25dc)(DMF)(2)] (1) (where pz25dc stands for pyrazine-2,5-dicarboxylate ligands) has been synthesized by the direct mixing method. This structure confirmed by a combination of physic-chemical methods features a 1-D linear polymeric chain. The local structure of a Zn atom in the unit cell of [Zn(pz25dc)(DMF)(2)] derived from EXAFS data is in a good agreement with that revealed from PXRD data. (C) 2011 Elsevier B. V. All rights reserved.
