Crystal Structure of Strontium 2-Furancarboxylate

Abstract

Abstract: The single crystal of strontium 2-furancarboxylate Sr₆(C₅H₃O₃)₁₂has been synthesized and grew in the aqueous solution and characterized by elementary analysis,IRspectra,density,DTAand TG,The structure of this compound is determined by X-ray single crystal diffraction analysis.The crystallographic data are as follows:monoclinic,space group P2₁/n,a=2.3090(7)nm,b=1.3376(4)nm,c=2.3093(6)nm,β=107.06(2)°,Z=4,R =0.0603.D_c=1.82×10³ kg/m³,D_m=1.81×10³ kg/m³.The 2-furancarboxyl groups in the compound are connected with the strontium ions through the oxo-bridging and then three-dimensional network is fromed.The average value of bond length of Sr─Ois 0.2641nm;but they are 0.2535 nm and 0.2861 nm when the oxygen atoms are from carboxyl group and furan nucleus respectively.

Key words: Strontium 2-furancarboxylate, Crystal structure, X-ray diffraction, Property
