The anions are linked by the octahedrally coordinated sodium cations into a three-dimensional network containing one-dimensional channels. Analysis of refinement data for the three isostructural compounds reveals rigid-body thermal motion behavior of the octahedral groups.
Several interionic hydrogen bonds are found, involving short N. The chain motif is consolidated into a layer structure by hydrogen bonds involving the coordinated and uncoordinated water molecules.
Almost all atoms lie on mirror planes.
This dianion serves as a spacer to connect adjacent square-pyramidal metal atoms into a helical chain that propagates along the b axis of the monoclinic unit cell.
O interactions, forming dimers in the crystal structure. Analysis of refinement data for the three isostructural compounds reveals rigid-body thermal motion behavior of the octahedral groups.
O interactions, forming dimers in the crystal structure.
These double chains are interconnected by weak O. The Cu and Lu atoms are doubly bridged by two phenolate O atoms afforded by the Schiff base ligand. O interactions generate a two-dimensional zigzag sheet.
The Mn atom lies on a center of symmetry. The metal atom lies on a twofold rotation axis.
The ZnII atom is six-coordinate with a distorted octahedral geometry.
The bipyridine-coordinated Zn atom on the threefold axis has a tetrahedral geometry, whereas the other Zn atom is coordinated by the O atoms of six different dianions in an octahedral geometry.
An infinite hydrogen-bonding structure between cation, anion and water molecules results in the formation of a double chain parallel to the b axis. The apical positions of the square-pyramidal copper coordination polyhedra are occupied by the water O atoms.
These double chains are interconnected by weak O. The O atoms are intramolecularly hydrogen bonded, as is usually observed for anti-isomer metal complexes of vic-dioximes.
The present study includes the determination of the H-atom parameters, which reveal an extensively hydrogen-bonded structure, as expected. O interactions generate a two-dimensional zigzag sheet. A mirror plane bisects the molecule, with the Ba and three water O atoms lying on the plane.
