Molecular formula : MW : CAS :
nature : a certain number of anion or polar molecules to pass through the coordination bond closely ion complexation at the center around which the material (sometimes also called Complex). These integrated complex at the center of anionic ion and molecular polarity of the total, saying the center median ions (coordination number). Coordination with the Center of anionic ion charge the same time be a neutral molecule, such as trichloroacetic three ammonia cobalt [Co (NH3) 3Cl3]; Not equal to the time of the cation - anion or, as four ammonia copper ions [ Cu (NH3) 4] 2-, six platinum chloride ions [PtCl6] 2- k, etc.. Coordination compounds (molecules or ions) has a certain space configuration, which is cis-isomer and heterogeneous phenomenon. For example, dichloro-4 ammonia cobalt ions [Co (N (NH3) 4Cl2] < sup> + / sup> two isomers, is cis-purple, green-yes.
