The title compound, {[Dy(C6H4NO2)(H 2O)2]2[Cu(C6H4NO2)2](C 6H4NO2)4} n , is a three-dimensional coordination polymer. The six-coordinate CuII atom, lying on an inversion center, is bonded to two O atoms from two monodentate isonicotinate ligands and four N atoms from four bridging isonicotinate ligands. Two Dy III atoms form a centrosymmetric dinuclear unit and each Dy III atom is eight-coordinated by six O atoms from five different isonicotinate ligands and two O atoms from two water mol-ecules. These metal coordination units are connected by ...
