Answer» aquachlorobis(ethylenediamine)cobalt(III) dichloride Explanation: the metal CO is cobalt. the ligands are “en” (ethylenediamine), H2O (aqua), and Cl- (chloro) Put the ligands in alphabetical order, then the metal name: aqua-chloro-ethylenediamine-cobalt There are two ethylenediamine ligands “(en)2” so use the prefix bis to indicate two of them (not di, SINCE “ethylenediamine” already contains a NUMERICAL prefix). So we have aquachlorobis(ethylenediamine)cobalt… The oxidation number of cobalt is +3, so use the Stock number (III), which is the corresponding ROMAN numeral. The overall charge of the complex is +2: positive, so do not add “ate” to the metal name. Then, using the name of the complex cation, name the ionic compound: aquachlorobis(ethylenediamine)cobalt(III) dichloride. The “di” in “dichloride” is not strictly necessary, since (as in CALCIUM chloride) it is implied by the charge of the cation. |
