the bridge. The bridging enforces a cisoid geometry of the ligand and prohibits its replacement by added water. An X-ray determination was carried out for [Eu(3b)3](ClO4)3, where 3b=3,3′; 5,3″-dimethylene tpy, which crystallizes in the monoclinic space group P21/c with a=11.908(4), b=15.768(5), c=29.513(9) A, β=93.60(2)°, μ=13.5 cm−1 and Z=4. The complex forms a tricapped trigonal prism with each of
