Each metal ion exhibits a distorted tetrahedral coordination geometry consisting of two pyridyl and two benzimidazole N atoms from four distinct ligands. Two metal ions are linked by two bep ligands to form a centrosymmetric 18-memberedM2(bep)2metallacycle, while adjacentM2(bep)2metallacycles are further interlinked by another two bep ligands resulting in a ladder-like array. In the extended structure, four adjacent ladder-like arrays are connected together through C—H...F, O—H...O and C—H...O hydrogen bonds between bep ligands, solvent molecules and counter-anions into a three-dimensional supramolecular structure.

In the title complex, [Co(C15H6ClO4)2(H2O)4]·2H2O, the CoIIion is bound by two carboxylate O atoms of two 5-chloro-9,10-anthraquinone-1-carboxylate anions and four water O atoms in atransconformation, forming an irregular octahedral coordination geometry. This arrangement is stabilized by intramolecular O—H...O hydrogen bonds between water and carboxylate. Further O—H...O hydrogen bonds between coordinating and non-coordinating water and carboxylate produce layers of molecules that extend parallel to (001). The organic ligands project above and below the plane. Those ligands of adjacent planes are interdigitated and there are π–π interactions between them with centroid–centroid distances of 3.552 (2) and 3.767 (2) Å that generate a three-dimensional supramolecular structure.

The Stability

The title complex, [Cu{μ3-O2CC6H3(NO2)2-3,5}(μ-OH)]n, features zigzag chains in which successive pairs of CuIIatoms are connected by OH bridges and bidentate carboxylate ligands, leading to six-membered Cu(O)(OCO)Cu rings. The zigzag chains are connected into a three-dimensional architecture by Cu—O(nitro) bonds. The coordination geometry of the CuIIatom is square-pyramidal, with the axial position occupied by the nitro O atom, which forms the longer Cu—O bond. Bifurcated hydroxy–nitro O—H...O hydrogen bonds contribute to the stability of the crystal structure.
