DOIAbstract
A complex of europium perchlorate with methylene bis(diphenylphosphine oxide) (HMPPO), [Eu(HMPPO)(4)](ClO4)(3). 2H(2)O has been synthesized and characterized by X-ray crystallography, infrared spectroscopy and thermal analysis. The X-ray structure of the complex shows Eu(III) is coordinated by eight oxygen atoms from four HMPPO ligands, forming a distorted square antiprism coordination geometry. The complex crystallizes in space group P-I with cell parameters a = 15.807(3), b = 17.868(4), c = 20.656(4) Angstrom, alpha = 86.85(3)degrees, beta = 82.33(3)degrees, gamma = 66.75(3)degrees. The final R-l and R-w are 0.0803 and 0.1994, respectively, for 9540 observed reflections [I > 2 sigma (I)]. Its luminescent properties have also been studi...
