It crystalizes in triclinic crystal system, space group P1, formula C36H110N8O55Lu4, Mr=2235.2,a=1.09787(7) nm, b=1.27603(10) nm, c=1.45903(10) nm; α=75.769(6)°, β=85.288(5)°, γ=71.577(6)°, V=1.8797(2) nm3,Z=1, Dc= 1.975 g·cm-3, F(000)=1106, μ=5.312 mm-1; R1=0.0239, wR2=0.0527 for 7156 reflections with I>2σ (I). In the complex, the lutetium ion is coordinated by two nitrogen atoms andsix oxygen atoms and the coordination number is 8. Its coordination polyhedron can be described as a distorted squareantiprism. The complex is of an infinite chain structure. The complex was characterized by elemental analysis, IR spectra and thermal analysis.展开更多

Each Lu3＋ ion is nine coodinated. Coordination polyhedron is a distorted trigonal prism. The carboxylate groups in the complex are bonded to the lutetium ion in the bridged bidentate and the bridged tridentate. Lutetium ions were linked by the bridged carboxylate groups, resulting in an infinite chain.展开更多
