| Abstract: | A new binuclear cage-like complex, [Eu2(TCM)2(DMSO)6]·2DMSO, was synthesized via the reaction of H3TCM(H3TCM={2,4,6-tris[(2-carboxyphenoxy)methyl]-1,3,5-trimethylbenzene}) and Eu3+. Single crystal X-ray diffraction study reveals a centro symmetric binuclear neutral entity, space group P21/c with a=1.5188(2) nm, b=1.7135(3) nm, c=1.7578(2) nm, β=95.34(2)°, V=4.5549(9) nm3, Z=4. In the complex, Eu3+ metal centers are bridged together by mono- and bidentate carboxylate groups from two ligands. The most interesting fact is that the size of solvent molecules has a great influence on the binuclear cage-like complex in the shape of binuclear cage, the coordination mode of carboxylate group and the coordination number of Eu3+. |
