Abstract

Literature reports of zinc(II) 2,2’-bipyridine crystal in chemistry journals by different researchers call for urgent attention because of its significance in catalysis, drug delivery, electrochemistry, materials chemistry, nanomedicine, and nanotechnology. Here, different coordination geometries reported include distorted tetrahedral, distorted octahedral, tetrahedral, octahedral, and square pyramidal geometries. Outside other forms of characterization, there are techniques of bite angle, such as computational chemistry and nuclear magnetic resonance (NMR); this study considered the concept of bite angle determined experimentally from X-ray crystallography. This led to the following research question: “how does the bite angle assess the different coordination geometries of zinc (II) 2,2’crystal reported in the literature of Chemistry journals?". In response to this question, qualitative research was used as the methodological approach to explore how the ligand field theory (LFT) supports the bite angle’s assessment of the coordination geometry of zinc(II) 2, 2’crystal using X-ray crystallography from recently reported literature in top-rated chemistry journals. Results showed how bite angles of similar zinc(II) 2,2’crystal compared with LFT to validate the reported coordination geometry of zinc(II) 2,2’-bipyridine crystal. The implication of this study is to enhance the relevance and importance of bite angle in zinc(II) 2, 2’crystal.
