Werner proposed that octahedral, tetrahedral, and square planar shapes are common in coordination compounds. Examples include [Co(NH₃)₆]³⁺, [Ni(CO)₄], and [PtCl₄]²⁻ representing octahedral, tetrahedral, and square planar entities, respectively.
According to Alfred Werner, what geometrical shapes are more common in coordination compounds of transition metals, and provide examples.

According to Alfred Werner, octahedral, tetrahedral, and square planar geometrical shapes are more common in coordination compounds of transition metals. In octahedral complexes like [Co(NH₃)₆]³⁺, six ligands surround the central metal. Tetrahedral complexes, as seen in [Ni(CO)₄], involve four ligands. Square planar complexes, exemplified by [PtCl₄]²⁻, exhibit a planar arrangement of four ligands. These shapes arise from the coordination number, representing the number of ligands directly attached to the central metal. Werner’s contributions revolutionized the understanding of these spatial arrangements, providing a foundation for modern coordination chemistry.
