摘要: 在水溶液中合成并培育了2-呋喃甲酸锐Sr6(C5H3O3)12单晶。经元素分析、红外光谱、差热热重分析、密度测定以及X射线衍射结构分析确定了该化合物的组成、结构和部分性质。结构分析结果表明:该晶体属单斜晶系,空间群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.Dc=1.82×103kg/m3,Dm=1.81×103kg/m3.化合物通过羧氧桥联形成三维网状结构,其中Sr-O键的平均键长为0.2641nm,而Sr-O(羧氧)为0.2535nm,Sr-O(呋喃环氧)为0.2861nm.

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.Dc=1.82×103 kg/m3,Dm=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.
