Edexcel A Level Chemistry:復習筆記6.2.7 Cis-platin
Cis-platin Sometimes, complexes with?four coordinate bonds?may adopt a?square planar?geometry instead of a tetrahedral one Cyanide ions (CN-) are the most common ligands to adopt this geomet...
Edexcel A Level Chemistry:復習筆記6.2.6 Tetrahedral Complexes
Tetrahedral Complexes When there are?four coordinate bonds?the complexes often have a?tetrahedral?shape Complexes with four?chloride?ions?most commonly adopt this geometry Chloride ligands a...
Edexcel A Level Chemistry:復習筆記6.2.5 Octahedral Complexes
Octahedral Complexes Octahedral?complexes are formed when a central metal atom or ion forms?six coordinate bonds This could be six coordinate bonds with?six?small,?monodentate?ligands Exampl...
Edexcel A Level Chemistry:復習筆記6.2.4 Ligands
Monodentate ligands Monodentate?ligands can form only?one?dative bond to the central metal ion This is because they have a single lone pair of electrons to form a dative bond with the metal ...
