Abstract:
The reactions between soluble 1D polymer [Ag{(η2:η1-A)}2] n [TEF] n , obtained from five-fold symmetric building blocks [Cp*Fe(η5-P5)] (A, Cp* = η5-C5Me5) and a weakly coordinating salt of Ag(i), and a series of ditopic-tetrahedral organometallic building blocks, [{CpMo(CO)2}2(η2-E2)] (E = P, As) or [{CpMo(CO)2}2(η2-PE)] (E = As, Sb), have been investigated. It is shown that, depending on the choice of the ditopic-tetrahedral complexes, a rational design of unprecedented heteroleptic 1D polymer or discrete molecular systems containing two different pnictogenyl building blocks is possible. Weak π-π interactions, adaptive coordination behavior of the Ag(i), argentophilic interactions and the fine-tuned electronic properties of the ditopic-tetrahedral complexes directed the product formation. The modular synthetic approach paves the way for hybrid systems containing heteroleptic pnictogen-rich supramolecular assemblies.

Structural Isomerism
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...

Metal-Ligand Bonds
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...
