配合物[Eu(NO3)2(tpy)(H2O)3]NO3的合成和晶体结构

The title complex [Eu(NO3)2(tpy)(H2O)3]NO3, has been synthesized by 2, 2': 6', 2”-terpyridyl (tpy) and Eu(NO3)2•6H2O, the complex was composed with one Eu(superscript 3+), one tpy, one two nitrate ion and three water molecular inside, outside of it was a nitrate ion. Its crystal and molecular structures were determined by X-ray diffraction methods. The crystal crystallizes in the triclinic system, space group P-1 with a=8.8803 (6) nm, b=11.2235 (7) nm, c=11.7461 (7)nm, a=88.8500 (10)°, β=69.1030 (10)°, y=74.6040 (10)°, V=1050.83 (12), Z=2, R=0.0153, wR=0.0598. The central europium ion is ten-coordinated and its coordination polyhedron can be described as a dicapped square antiprism.
