Abstract
The mononuclear complex [Na(C7H6O4)(H2O)3](C7H5O4) · 2H2O has been synthesized and characterized by IR, single crystal X-ray and thermal analysis. The compound crystallizes in the monoclinic space group P21 with a = 3.623(2) A, b = 15.872(6) A, c = 15.650(5) A, β = 93.13(4)°, V = 896.6(7) A3 and Z = 2. The central sodium ion is six coordinated with distorted octahedral geometry by two oxygen atoms from two bridging 3,5-dihydroxybenzoate ligands and four ones from different water molecules. The notable feature of the title complex is the formation of a three-dimensional network, through the combination of coordination bonds, hydrogen bonds and π···π interactions. There are one-dimensional channels in the structure, filled in by water molecules. The compound dehydrates in the temperature range of 70–125 °C and then is stable up to 230 °C.
