Single crystals of Eu(ClO 4 ) 3 have been obtained by slow dehydration of a hydrous product prepared by the reaction of Eu 2 O 3 with HClO 4 . The crystal structure (hexagonal, P6 3 /m, Z = 2, a = 924.96(9), c = 574.86(8) pm) consists of tricapped trigonal [EuO 9 ] prisms and [ClO 4 ] tetrahedra. One of the oxygen atoms in the ClO 4 group does not coordinate to Eu 3+ and points towards the empty channel which runs in the direction [001].
