Summary
Transition metal carbyne chemistry is expanding beyond traditional organic groups to include heavier pnictogen elements. This review explores these novel pnictogen-functionalised carbyne ligands and their unique properties.
Area of Science:
- Organometallic Chemistry
- Main-group Chemistry
- Inorganic Chemistry
Background:
- Historically, transition metal carbyne complexes (Ln M≡CR) featured hydrocarbyl or amino substituents.
- The incorporation of heavier p-block elements into carbyne ligands is a recent and developing area.
Purpose of the Study:
- To review the synthesis, properties, and reactivity of heavier pnictogen-functionalised C1 ligands (MCARn).
- To compare these novel complexes with traditional carbyne species.
- To discuss related phospha-isonitrile and cya-phosphide/arside ligands.
Main Methods:
- Literature review of organometallic and main-group chemistry.
- Analysis of synthetic routes, spectroscopic properties, and reactivity patterns.
- Comparative study of traditional versus pnictogen-functionalised carbyne complexes.
Main Results:
- Emergence of heavier pnictogen-functionalised carbyne ligands (A=P, As, Sb, Bi).
- Distinctive chemical properties and reactivities compared to hydrocarbyl/amino carbynes.
- Recent advances in related phospha-isonitrile and cya-phosphide/arside ligands.
Conclusions:
- Heavier pnictogen-functionalised carbyne chemistry represents a significant expansion of the field.
- These ligands offer new avenues for catalyst design and materials science.
- Continued exploration promises further diversification of transition metal C1 chemistry.

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.

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...

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...

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...

Carbocations are one of the reaction intermediates formed during several nucleophilic substitutions or elimination reactions. A carbocation is an electron-deficient species with the central carbon atom having six electrons and three bonded atoms. The central carbon in a carbocation is sp2 hybridized with trigonal planar geometry. It has an empty p orbital perpendicular to the plane of the structure that can accept electrons. Thus, carbocations act as strong electrophiles and may react with any...

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...
