Coordination polymer {[La(NO3)3]2•L3}n {L=1,4-bis{[2'-(benzylaminocarbonyl)-phenoxyl]-methyl}benzene has been synthesized by the reaction of an aryl amide type bis-monodentate ligand and La(NO3)3•6H2O, and the crystal structure of this complex has been characterized by X-ray diffraction analysis.The crystal structure belongs to triclinic system with space group P1, a=1.1298(2) nm, b=1.2689(1) nm, c=2.1030(3) nm, α=81.189(9)°, β=80.95(1)°, γ=65.832(9)°, V=2.7032(6) nm3, Z=2, R=0.0267, wR=0.0679. The La3+ took nine-coordinate in a distorted tricapped trigonal prism. The complex formed 1D coordination polymer consisting of rings connected by chains alternately by the bridging of ligand. These 1D polymers were packed in an independent style for the lack of inter chain hydrogen bond and π-π intreaction.

Key words: bis-monodentate, aryl amide, coordination polymer, synthesis, crystal structure
