Synthesis and Crystal Structure of a 2D Sm(III) Coordination Polymer: {[Sm2L3(H2O)4]·(4,4'-bpy)·3H2O}n
摘要:
A new compound, {[Sm2L3(H2O)4]·(4,4'-bpy)·3H2O}n (1, H2L=5-(3-pyridyl methoxy) isophthalic acid, 4,4'-bpy=4,4'-dipyridyl), has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction. It crystallizes in triclinic, space group P1 with a=11.266(2), b=15.530(3), c=16.711(3) Å, α=112.803(3), β=90.526(1), γ=94.006(3)°, V=2686.6(9) Å3, Z=2, Dc=1.727 g/cm3, μ=2.251 mm-1, F(000)=1392, S=0.999, the final R=0.0296 and wR=0.1058. In the title compound, two crystallographically independent Sm3+ cations are bridged by the carboxyl group of L2- ligands to form two different {Sm2} binuclear subunits which are further connected by two distinct L2- ligands to shape a 1D chain, and such 1D chains are linked up to generate a 2D coordination polymer by another crystallographically unique L2- ligand. The thermogravimetric analysis and luminescent property of the title compound were also investigated.
