Abstract:
The title polymer, [Cu(2)Cl(2)(C(9)H(9)N(5))(2)](n), has been prepared by the solvothermal treatment of CuCl with 4-(2-allyl-2H-tetra-zol-5-yl)pyridine. The crystal structure shows that the title compound is a homometallic Cu(I)-olefin coordination polymer, in which the Cu(2)Cl(2) nodes are bridged by two olefin ligands. The asymmetric unit contains one-half of the monomer, the complete monomer having twofold rotation symmetry. The coordination environment of Cu(I) is slightly distorted tetra-hedral, with coordination sites being two μ(2)-Cl atoms, one pyridine N atom of an organic ligand and one allylic double bond of a symmetry-related ligand. Each organic mol-ecule behaves as a bidentate ligand, connecting two neighboring Cu(2)Cl(2) dimers in the polymeric chain, which runs along [010].

Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...

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...

Structure of Conjugated Dienes
Conjugated dienes are compounds characterized by the presence of alternating double and single bonds. In a conjugated system like 1,3-butadiene, the unhybridized 2p orbital on each carbon overlaps continuously, allowing the π electrons to be delocalized across the entire molecule. In contrast, this type of overlap does not occur in cumulated and isolated dienes, such as 2,3-pentadiene and 1,4-pentadiene, respectively. Instead, the π electrons remain localized between the double...
