What is the charge on the anion in the coordination compound K2[Pt(NO2)2Cl2]? The pair of brackets “[‘” and “]” indicate the presence of a metal complex, and this collection of atoms/ions can be thought of as one molecular species (in this case an anion). Platinum is at the center of the complex with NO2− (through the N) and Cl− forming coordinate bonds with the Pt. Draw the Lewis structures of NO2− (nitro) and Cl−. Circle the electron pair in each...
