摘　　要：A new Eu（III） complex from 2,2＇-bipyridine（2,2＇-bipy） and 1,3,5-triazine-2-4,6-tri（L-alanine）（H3L）, {[Eu（L）（2,2＇-bipy）]（H2O）}n（1）, has been synthesized and characterized. The X-ray structure analysis reveals that 1 is an infinite one-dimensional chain-like coordination polymer consisting of dinuclear lanthanide building blocks. The 1D chains are further assembled into a 2D supramolecular architecture through π···π interaction among chains. Crystal data for 1： Eu C22H25N8O7, triclinic, space group P1, a = 11.3965（1）, b = 11.5112（6）, c = 12.0404（1）A, α = 61.970（11）, β = 86.698（15）, γ = 65.254（12）°, V = 1247.0（2） A3 and Z = 2. Solid-state photoluminescence property of 1 was investigated, which exhibited remarkable red luminescence emissions with high quantum yield up to 37%.A new Eu（III） complex from 2,2＇-bipyridine（2,2＇-bipy） and 1,3,5-triazine-2-4,6-tri（L-alanine）（H3L）, {[Eu（L）（2,2＇-bipy）]（H2O）}n（1）, has been synthesized and characterized.
