| Abstract: The title complex, {[Eu(L)(HL)]·2H2O}n 1, where H2L=5-(isonicotinamido)isophthalic acid, was synthes-ized and its crystal structure was determined by X-ray diffraction analysis. The crystal is of monoclinic, space group P21/c with a=1.344 02(18) nm，b=1.377 50(18) nm，c=1.623 07(15) nm，β=115.820(8)°，V=2.704 9(6) nm3，Z=4，Mr=757.45，Dc=1.860 g·cm-3，μ=2.396 mm-1，F(000)=1 504，Rint=0.051 4，R1=0.032 2，wR2=0.089 1. In the complex, the central Eu(Ⅲ) atom is eight-coordinated by eight carboxylate oxygen atoms, completing a distorted bicapped trigonal prismatic geometry. The molecules are connected to form a 2D bilayer structure bridged by 5-(isonicotinamido)isophthalic acid. CCDC: 826595. |
