| Abstract: | A alkaline earth metal-organic complex,namely,Sr(BuTA)0.5(H2O)2 (1) (H4BuTA=1,2,3,4-Butanetetra-carboxylic acid),was obtained in water system by hydrothermal method based on flexible multi-carboxylate ligand.The title complex was characterized by elemental analysis and X-ray crystallography.The result of structural analysis shows that the complex 1 crystallizes in monoclinic,space group P21/c with a=0.870 03(5) nm,b=0.793 03(5) nm,c=1.268 07(5) nm,β=127.689(3)°,V=0.692 36(7) nm3,g=4,Dc=2.290 g·cm-3,F(000)=468,μ=7.768 cm-1,the final R =0.015 8,wR =0.037 7.In complex 1,the coordination environment of Sr(Ⅱ) is eightcoordinated with square antiprismatic geometry.The metal ions and ligands link each other to form a 3D framework of (46)2(412.612.84) topology,in which the BuTA2- anions act as rare 8-connected topological blocks.The thermal stability of complex 1 was also investigated.CCDC:825571. |
