Summary
New homochiral metal-organic frameworks (MOFs) were synthesized using a novel binaphthyl-based ligand and Cu(II) nodes. These MOFs exhibit complex hierarchical structures, including interpenetrating 3D frameworks and threaded 2D/1D networks.
Area of Science:
- Materials Chemistry
- Coordination Chemistry
- Crystallography
Background:
- Metal-organic frameworks (MOFs) offer tunable structures for diverse applications.
- Homochiral MOFs are crucial for enantioselective separations and catalysis.
- Developing novel ligands is key to constructing complex MOF architectures.
Purpose of the Study:
- To synthesize and characterize novel hierarchically ordered homochiral metal-organic frameworks.
- To explore the structural diversity achievable with a new binaphthyl-based bridging ligand.
- To investigate the self-assembly behavior of copper(II)-based MOFs.
Main Methods:
- Solvothermal synthesis of metal-organic frameworks.
- Single-crystal X-ray diffraction for structural elucidation.
- Characterization of ligand and resulting framework structures.
Main Results:
- Two distinct MOF structures, (1) and (2), were successfully synthesized and characterized.
- Compound (1) features interpenetrating 1D ladders forming a 3D framework.
- Compound (2) displays a unique topology with 2D grids threaded by 1D coordination polymers.
Conclusions:
- The study demonstrates the successful construction of complex homochiral MOFs with hierarchical structures.
- The novel ligand enables the formation of intricate and interpenetrating network topologies.
- These findings contribute to the design principles for advanced MOF materials.

02:37Metallic Solids
Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability. Many...

02:57Coordination Number and Geometry
For transition metal complexes, the coordination number determines the geometry around the central metal ion. Table 1 compares coordination numbers to molecular geometry. The most common structures of the complexes in coordination compounds are octahedral, tetrahedral, and square planar.
02:22Structures of Solids
Solids in which the atoms, ions, or molecules are arranged in a definite repeating pattern are known as crystalline solids. Metals and ionic compounds typically form ordered, crystalline solids. A crystalline solid has a precise melting temperature because each atom or molecule of the same type is held in place with the same forces or energy. Amorphous solids or non-crystalline solids (or, sometimes, glasses) which lack an ordered internal structure and are randomly arranged. Substances that...
02:42Ionic Crystal Structures
Ionic crystals consist of two or more different kinds of ions that usually have different sizes. The packing of these ions into a crystal structure is more complex than the packing of metal atoms that are the same size.
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

Isomerism in Complexes
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...

01:23Properties of Organometallic Compounds
Organometallic compounds are compounds that contain a carbon–metal bond. Carbon belongs to an organyl group like alkyl, aryl, allyl, or benzyl groups. The metal can be from Group I or Group II of the periodic table, a transition metal, or a semimetal.
