Triimidazolium tris­(pyridine-26-di­carboxyl­ato)dysprosate(III) trihydrate

摘要

The structure of the title compound, (C3N2H5)3[Dy(C7H3NO4)3]·3H2O, 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-dicarboxyl­ate anions. Three protonated imidazole mol­ecules act as counter-cations and three lattice water mol­ecules are also present. Numerous N—H⋯O and O—H⋯O hydrogen bonding inter­actions, some of which are bifurcated, help to stabilize the packing of the structure.
