Abstract
In the title complex, {[Ag2Nd(C6H4NO2)4(H2O)2]NO3·H2O}n, the NdIII ion is coordinated by eight O atoms from six isonicotinate ligands and two water molecules in a distorted square antiprismatic geometry. Each AgI ion is coordinated by two N atoms from two different isonicotinate ligands. The crystal structure exhibits a two-dimensional heterometallic polymeric layer. O—H⋯O hydrogen bonds involving the coordinated and uncoordinated water molecules and intralayer π–π interactions between the pyridine rings [centroid–centroid distances = 3.571 (2) and 3.569 (2) Å] are observed. Each layer interacts with two neighboring ones via Ag⋯O(H2O) contacts and interlayer π–π interactions [centroid–centroid distances = 3.479 (3) to 3.530 (3) Å], leading to a three-dimensional supramolecular network.
