To fulfill this demand, nanostructured metal oxides can be used as active materials for chemical/gas sensors due to their high crystallinity, remarkable physical/chemical properties, ease of synthesis, and low cost. In particular, (1D) one-dimensional metal oxides nanostructures, such as nanowires, exhibit a fast response, selectivity, and stability due to their high surface-to-volume ratio, well-defined crystal orientations, controlled unidirectional electrical properties, and self-heating phenomenon. Moreover, with the availability of large-scale production methods for nanowire growth such as thermal oxidation and evaporation-condensation growth, the development of highly efficient, low cost, portable, and stable chemical sensing devices is possible. In the last two decades, tremendous advances have benhance the performance of nanowire-based chemical sensor are presented in detail.The complexation process between anionic ZCl4- (Z = P, As, Sb) and neutral NCH and pyridine, as well as the CN- anion, is studied in both the gas phase and aqueous solution by high-level ab initio calculations. Despite the absence of a positively charged σ-hole on ZCl4-, a pnicogen bond (ZB) holds all of these complexes together. The dimerization induces the ZCl4- to rearrange internally from a see-saw to a square geometry. The complexation process is endothermic for both HCN and CN- in the gas phase but for different reasons. The approach of CN- to ZCl4- must overcome anion-anion Coulomb repulsion, while HCN is a much weaker base. The intermediate nucleophilicity of pyridine leads to an exothermic dimerization reaction despite the deformation of the ZCl4- structure. The dimers must traverse an energy barrier in o
