Abstract
The asymmetric unit of the title compound, {[AgNd(C6H4NO2)2(C2O4)]·2H2O}n, contains one NdIII atom, one AgI atom, one oxalate ligand, two nicotinate ligands and two uncoordinated water molecules. The NdIII atom is eight-coordinated in a distorted square-antiprismatic coordination geometry by four O atoms from two oxalate ligands and four O atoms from four nicotinate ligands. The AgI atom has a T-shaped configuration, defined by two N atoms from two nicotinate ligands and one O atom from one oxalate ligand. The nicotinate and oxalate ligands link the Nd and Ag atoms into a three-dimensional coordination framework. O—H⋯O and O—H⋯N hydrogen bonds donated by water molecules are observed in the crystal.
