【Abstract】 Two heteronuclear/homonuclear coordination polymers {[Mn Sm2(INAIP)4(H2O)4]·2H2O}n(1) and {[Sm(INAIP)(HINAIP)]·2H2O}n(2), where H2INAIP=5-(isonicotinamido)isophthalic acid, were synthesized in a pot and their crystal structures were determined by X-ray diffraction analysis. Complex 1 crystallizes in the triclinic system, space group P1 with a=1.018 8(5) nm, b=1.083 86(6) nm, c=1.387 21(8) nm, V=1.475(14) nm3, Z=1, Dc=1.802 g·cm-3, μ=2.271 mm-1, F(000)=793, Rint=0.010 5, R1=0.051 2, w R2=0.131 9. Complex 2 is of monoclinic system, space group P21/c with a=1.343 05(18) nm, b=1.376 5(17) nm, c=1.624 08(15) nm, V=2.702 8(6) nm3, Z=4, Dc=1.861 g·cm-3, μ=2.251 mm-1, F(000)=1 500, Rint=0.051 4, R1=0.032 2, w R2=0.088 7. In complex 1, the 2D Sm-carboxylate layer is linked by Mn-N and Mn-O interaction into complicated 3D framework. However, for complex 2, the central Sm(Ⅲ) atom is eight-coordinated by eight carboxylate oxygen atoms. The molecules are connected to form a 2D bilayer structure bridged by 5-(isonicotinamido)isophthalic acid. Furthermore, complex 1shows adsorption behavior of CO2 with almost no N2 uptake,and the luminescent property of complexes 1 and 2has also been investigated. CCDC: 1045729, 1; 1045730, 2.更多还原
