Triimidazolium tris-(pyridine-2,6-di-carboxyl-ato)dysprosate(III) trihydrate.

ABSTRACT: The structure of the title compound, (C(3)N(2)H(5))(3)[Dy(C(7)H(3)NO(4))(3)]·3H(2)O, contains a mononuclear Dy(III) complex with the rare earth metal cation in a distorted tricapped trigonal-prismatic environment. The Dy(III) ion is in each case O,N,O'-chelated by three tridentate pyridine-2,6-dicarboxyl-ate anions. Three protonated imidazole mol-ecules act as counter-cations and three lattice water mol-ecules are also present. Numerous N-H⋯O and O-H⋯O hydrogen bonding inter-actions, some of which are bifurcated, help to stabilize the packing of the structure.
