| Abstract: By using hydrothermal method, the reaction of 5-((pyridine-3-ylmethyl)amino)isophthalic acid (H2L) with yttrium nitrate led to the formation of a novel yttrium(Ⅲ) complex, namely, YL(HL)·2H2O (1), with interesting two-dimensional (2D) topology. The title complex was characterized by elemental analysis and IR spectroscopy and its structure was determined by single crystal X-ray structural analysis. The result of structural analysis shows that the 1 crystallizes in triclinic, space group P1 with a=1.015 35(11) nm, b=1.083 33(12) nm, c=1.287 40(14) nm, α=70.9430(10)°, β=127.689(3)°, γ=84.0680(10)°, V=1.317 0(2) nm3, Z=2, Dc=1.680 g·cm-3, F(000)=680, μ=2.284 cm-1, R=0.056 2, wR=0.160 0. The Y(Ⅲ) atoms was eight-coordinated with carboxylate O atoms in square-antiprismatic geometry. In complex 1, the 2D layer comprised of μ2/μ3-ligands and 5-connected Y(Ⅲ) centers is rare example of 2-nodal net of (42.6)(42.67.8) topology. The XPRD and TGA analysis were also investigated.
