Werner’s coordination theory, while pioneering, faced limitations in explaining certain aspects of coordination compounds. It struggled to elucidate why only specific elements formed such compounds, the directional properties of the bonds, and the characteristic magnetic and optical properties. The theory lacked a comprehensive explanation for these phenomena. To address these gaps, alternative theories like Valence Bond Theory (VBT), Crystal Field Theory (CFT), Ligand Field Theory (LFT), and Molecular Orbital Theory (MOT) were developed, offering more nuanced perspectives on the nature of bonding and properties exhibited by coordination compounds.

Valence Bond Theory (VBT) proposes a correlation between the magnetic behavior of coordination compounds and their geometry. Magnetic data, obtained through experiments like magnetic susceptibility measurements, can be used to predict the geometry. Diamagnetic complexes with no unpaired electrons often indicate octahedral geometry, while paramagnetic complexes with unpaired electrons suggest alternative geometries. For example, in [Co(NH₃)₆]³⁺, diamagnetism signifies octahedral geometry due to the absence of unpaired electrons. In [CoF₆]³⁻, paramagnetism indicates an outer orbital complex with sp³d² hybridization, suggesting a distorted octahedral geometry with directional properties in the ligand-metal interactions.
The hybridization scheme for the diamagnetic octahedral complex [Co(NH₃)₆]³⁺ involves the hybridization of cobalt's 3d, 4s, and three 4p orbitals, resulting in six equivalent sp³d² hybrid orbitals. Each ammonia ligand donates an electron pair for bonding. Diamagnetism arises due to the absence of unRead more
