Abstract
In the title complex, [Ag2La(C6H4NO2)4(ClO4)(H2O)5]n, the LaIII atom, lying on a twofold rotation axis, is eight-coordinated by four O atoms from four nicotinate (nic) ligands and four water molecules in a distorted square-antiprismatic coordination geometry. The AgI atom is coordinated in an almost linear fashion by two pyridyl N atoms of two nic ligands. The linear coordination is augmented by weak interactions with one O atom from a half-occupied ClO4 − anion and a water molecule lying on a twofold axis. Two Ag(nic)2 units connect two La atoms, forming a cyclic unit. These units are further extended into an infinite zigzag chain. The chains are bridged by the disordered perchlorate ions via weak Ag—O [2.678 (2) Å] interactions. O—H⋯O hydrogen bonds, weak Ag⋯Ag [3.3340 (15) Å] interactions and π–π interactions between the pyridyl rings [centroid–centroid distance = 3.656 (2) Å] lead to a three-dimensional network.
