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