A coordination complex consists of a central atom or ion, which is usually metallic and is called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands or complexing agents. stream On the contrary, very little is known about the photophysics and photochemistry of coordination compounds of the main group metals.2 Although this lack of knowledge seems to be quite surprising there are some obvious reasons which hamper the study of main group metal complexes. Many metal-containing compounds, especially those of transition metals, are coordination complexes. << << >> NCERT Class 12 Chemistry Chapter 9 Coordination Compounds Notes are one of the best pieces of study material that students can get as it will aid them to study better and reduce some stress that they might face while the hectic year ahead.
