Abstract
In the title compound, {[Ag2Gd(C6H4NO2)4(H2O)2]NO3·H2O}n, the GdIII ion is coordinated by eight O atoms from six isonicotinate ligands and two water molecules in a distorted square antiprismatic geometry. Two AgI ions are each bonded to two N atoms from two isonicotinate ligands in a linear or bow-like fashion [N—Ag—N angles = 178.6 (2) and 147.1 (2)°]. These metal ions are connected by the isonicotinate ligands into a layer parallel to (010). O—H⋯O hydrogen bonds donated by the coordinated and uncoordinated water molecules and intralayer π–π stacking interactions between the pyridine rings [centroid–centroid distances = 3.551 (4) and 3.555 (4) Å] are observed. The layers interact with each other by interlayer Ag⋯O(aqua) contacts [2.731 (4) Å] and π–π stacking interactions between the pyridine rings [centroid–centroid distances = 3.466 (3) and 3.516 (3) Å], resulting in the formation of a three-dimensional supramolecular structure.
