The CuII ion assumes a distorted square-pyramidal coordination geometry. The molecules are stacked along the b axis in a herring-bone fashion. The Cu atom lies on a center of inversion. O hydrogen bonds complete the structure. In the crystal structure, adjacent molecules are linked by Ni. The binuclear molecules are linked by hydrogen bonds, forming a three-dimensional supramolecular architecture. O hydrogen bonds lead to a three-dimensional network in the crystal structure. These are connected by TBC dianions, forming a three-dimensional network. The Ni atom lies on a centre of symmetry and the water O atom lies on a twofold rotation axis. O hydrogen bonds complete the structure. An ideal three-dimensional framework is formed by the flexible phenoxyacetate ligands via intramolecular hydrogen-bond interactions. Thus, the AgI centre can be considered as being hexacoordinated. The tridentate BIPI ligand is essentially planar. The NiII atom is in a distorted octahedral geometry. The CuII ion assumes a distorted square-pyramidal coordination geometry. The chloride anions are hydrogen bonded with complex cations, resulting in a three-dimensional supramolecular architecture. In the crystal structure, adjacent molecules are linked by Ni. One independent succinate ligand, located on an inversion center, is in a bidentate coordination mode, exhibiting an anti conformation. The CuII ion assumes a distorted square-pyramidal coordination geometry. The tridentate BIPI ligand is essentially planar. F interactions, leading to a five-coordinated Ag atom. One independent succinate ligand, located on an inversion center, is in a bidentate coordination mode, exhibiting an anti conformation. O hydrogen bonds to form a two-dimensional network. The Cu atom lies on a center of inversion. O intra- and intermolecular interactions, forming a three-dimensional network. The four coordinated water molecules and the hydroxyl atoms from the ligand form intermolecular hydrogen bonds, resulting in a three-dimensional supramolecular network. O hydrogen bonds that link the cations along c into positively charged pillars. The molecule is centrosymmetric. The tridentate BIPI ligand is essentially planar. O hydrogen bonds to form a two-dimensional network. Four acetate groups bridge two CuII ions, forming a dinuclear molecule. Four acetate groups bridge two CuII ions, forming a dinuclear molecule. The molecule is centrosymmetric. The cation lies on a crystallographic twofold rotation axis and the anion lies on a centre of inversion. O intra- and intermolecular interactions, forming a three-dimensional network. Four acetate groups bridge two CuII ions, forming a dinuclear molecule. O hydrogen bonds link the molecules into an infinite two-dimensional network, with these networks held together by van der Waals forces to generate a layer structure. |
