Summary
Pentaphosphaferrocenes serve as versatile building blocks for creating novel coordination polymers (CPs) through self-assembly with coinage metal salts and aromatic dinitriles. Steric and structural factors of these components dictate the final CP structures.
Area of Science:
- Organometallic Chemistry
- Supramolecular Chemistry
- Materials Science
Background:
- Pentaphosphaferrocenes, specifically [Cp*Fe(η⁵-P₅)] and [Cp''Fe(η⁵-P₅)], are effective precursors for supramolecular assemblies.
- Coinage metal salts with weakly coordinating anions, such as AgSbF₆, are suitable partners for forming coordination polymers.
Purpose of the Study:
- To investigate the three-component self-assembly of pentaphosphaferrocenes, coinage metal salts, and aromatic dinitriles.
- To explore the influence of steric bulk on cyclopentadienyl ligands and the rigidity of dinitrile linkers on coordination polymer formation.
Main Methods:
- One-pot reaction synthesis involving pentaphosphaferrocenes, silver hexafluoroantimonate, and isomeric aromatic dinitriles.
- Characterization techniques including NMR spectroscopy, mass spectrometry, elemental analysis, and single-crystal X-ray diffraction.
Main Results:
- Formation of various coordination polymers (CPs) through a three-component self-assembly process.
- Demonstration that the steric properties of cyclopentadienyl ligands and the structural rigidity of dinitriles are critical factors in determining the isolated CP structures.
Conclusions:
- Pentaphosphaferrocenes are valuable synthons for constructing diverse coordination polymers.
- The rational design of building blocks, considering steric and structural features, enables control over the self-assembly of complex coordination architectures.

02:42Valence Bond Theory
9.0K
Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...

00:57Cationic Chain-Growth Polymerization: Mechanism
2.4K
The cationic polymerization mechanism consists of three steps: initiation, propagation, and termination. In the initiation step of the polymerization process, the π bond of a monomer gets protonated by the Lewis acid catalyst, which is formed from boron trifluoride and water. The protonation of the π bond generates a carbocation stabilized by the electron‐donating group. In the propagation step, the π bond of the second monomer acts as a nucleophile and attacks the...

The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

21.9K
In most main group element compounds, the valence electrons of the isolated atoms combine to form chemical bonds that satisfy the octet rule. For instance, the four valence electrons of carbon overlap with electrons from four hydrogen atoms to form CH4. The one valence electron leaves sodium and adds to the seven valence electrons of chlorine to form the ionic formula unit NaCl (Figure 1a). Transition metals do not normally bond in this fashion. They primarily form coordinate covalent bonds, a...

01:18Assembly of Cytoskeletal Filaments
21.2K
Cytoskeletal filaments are polymeric forms of smaller protein subunits. However, individual cytoskeletal filaments may easily disassemble or associate with other similar filaments to form rigid structures. Microfilaments, made of actin monomers, rely on actin-binding proteins to form bundles and create networks of individual actin filaments. Microtubules rely on microtubule-associated proteins (MAPs) to form sturdy cylindrical structures. However, the proteins involved in forming complex...

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.
