COORDINATION POLYMER OF STRONTIUM (II) BASED ON PHTHALIC ACID AND PYRAZINE ADDUCT

The coordination polymer of Sr (II), with the chemical formula {SrL1 (L2)0.5·(H2O)0.36}n (L1 = phthalic acid anion and L2 pyrazine), have been synthesized by interaction sodium phthalate a water-soluble strontium salt pyrazine in aqueous medium further evaporation an solution characterized IR spectroscopic, elemental, single-crystal X-ray diffraction thermal analysis. results XRD analysis showed that synthesis product has single-phase is well-identified means: 12.73; 11.41; 9.04 showing unit cell parameters this compound are approximately equal to 12.74, b 11.41, c Å. spectroscopic studies acts as chelate bridging ligand. Thermographic stable up temperature ̴ 2000С
