Ethylenediamine complexes
WebDec 1, 2016 · Ethylenediamine is H X 2 N − C H X 2 − C H X 2 − N H X 2 and both nitrogens can form coordinate bonds. In the next step, identify how many coordinating entities you have in total and thus what the maximum coordination number is. As mentioned, each e n has two potentially coordinating nitrogens for a total of six dative bonds. Webcis-Dichlorobis (ethylenediamine)cobalt (III) chloride is a salt with the formula [CoCl 2 (en) 2 ]Cl (en = ethylenediamine ). The salt consists of a cationic coordination complex and a chloride anion. It is a violet diamagnetic solid that is soluble in water.
