摘要：

A polynuclear europium(III) complex of the formula [Eu(bphsb)(1.5)(NO3)(3)](n) [bphsb = 1.4-bis(phenylsulfinyl)butane] has been prepared and its structure and luminescent properties have been determined by X-ray diffraction and spectral measurements. The structure consists of Eu-III ions bridged by bidentate bphsb ligands and coordinated by NO3- groups to make a polynuclear neutral complex. The europium ion is nine-coordinated and the geometry around the Eu-III is that of a distorted tricapped trigonal prism. The polynuclear complex has a framework structure with 54-membered macrocyclic rings, each containing six europium ions. The complex exhibits sensitized luminescence that originates from D-5(0) state to F-7(J) Stark levels. Copyright (C) 1997 Elsevier Science Ltd.
