Edexcel A Level Chemistry:复习笔记6.2.8 Haemoglobin
Haemoglobin Haemoglobin is one of nature's complexes using a transition metal ion The haem molecule is a complex with iron(II) at its centre The haemoglobin complex contains a multidentate l...
Edexcel A Level Chemistry:复习笔记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:复习笔记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:复习笔记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:复习笔记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 ...
Edexcel A Level Chemistry:复习笔记6.2.3 Coloured Ions
Coloured Ions Perception of colour Most transition metal compounds appear coloured. This is because they absorb energy corresponding to certain parts of the visible electromagnetic spectrum ...
