Synthesis and Characterization of a V‐Shaped Heteroleptic Hg(II) Complex with Enhanced Conductivity
Abstract In this article, we report the synthesis of the first example of V‐shaped unique structure of complex {[Hg(nvp) 2 (NCS)(Cl)][Hg(nvp) 2 (NCS) 2 ]} ( 1 ; 4‐nvp = 4‐(1‐naphthylvinyl)pyridine and SCN − = thiocyanate) containing two heteroleptic monometallic Hg(II) based units. The complex 1 undergoes a variety of conventional and unconventional supramolecular interactions, such as hydrogen bonding, chalcogen⋯π, halogen⋯π, π⋯π and chalcogen⋯halogen interactions to generate higher dimensional architecture. These supramolecular assemblies, along with the presence of d 10 metal ion Hg(II) promote large charge transportation and make the material to behave as a semiconductor as well as Schottky diode. The complex shows high conductivity (1.73 × 10 −3 S/m), maintaining a 1.54 ideality factor. This allows quick response times with low noise, enhancing signal clarity and efficiency in electronic devices, making it ideal for high‐speed photodetectors. The semiconducting behavior is also realized by density functional theory (DFT) computed band gap study.
