In the title complex, [Dy(C(7)H(3)NO(4))(C(7)H(4)NO(4))](n), one of the ligands is fully deprotonated while the second has lost only one H atom. Each Dy(III) ion is coordinated by six O atoms and two N atoms from two pyridine-2,6-dicarboxyl-ate and two 6-carboxy-picolinate ligands, displaying a bicapped trigonal-prismatic geometry. The average Dy-O bond distance is 2.40?Å, some 0.1Å longer than the corresponding Ho-O distance in the isotypic holmium complex. Adjacent Dy(III) ions are linked by the pyridine-2,6-dicarboxyl-ate ligands, forming a layer in (100). These layers are further connected by ?-? stacking inter-actions between neighboring pyridyl rings [centroid-centroid distance = 3.827?(3)?Å] and C-H?O hydrogen-bonding inter-actions, assembling a three-dimensional supra-molecular network. Within each layer, there are other ?-? stacking inter-actions between neighboring pyridyl rings [centroid-centroid distance = 3.501?(2)?Å] and O-H?O and C-H?O hydrogen-bonding inter-actions, which further stabilize the structure.
