Abstract
A new europium (III) complex, [Eu(NO3)(6)]{[(Hphen)(6). 2NO(3)]. NO3} (1) w as prepared and structurally characterized in which Eu3+ is 12-coordinated to six bidentate nitrates. The coordination polyhedron around Eu3+ was desc ribed as a slightly distorted icosahedron. The six mono-protonated 1,10-phe nanthrolines do not coordinate to the Eu3+ directively due to the formation of hydrogen bonds in form of O . . .H-N with two nitrates and also the for mation of two face-to-face trigonal plates within which one free nitrate is sandwiched. 1 exhibits strong red and blue fluorescence when it was irradi ated by UV light.
