The title complex Eu(PMBP) 3 · 2 H2 O has been synthesized. The crystal is monoclinic with space group of P2 1 / n,a=14 .982 1(1) ,b=14 .75 18(8) ,c=2 4 .4 979(9) ,β=10 1. 5 2°. Each europium ion is coordinated by 8oxygen atoms,contributed by three PMBP and two watermolecules,arranged atthevertices of a square antiprism. The electronicstructure of the complex was calculated using the INDO/ F program.The molecular orbital energy, charge distribution,and Mulliken bond order ofthe structure and bonding characters of Eu L3 · 2 H2 O have been discussed.
