What is the IUPAC name of [Pt(NH 3 ) 2 Cl(NO 2 )]?

In the coordination compound [Pt(NH 3 ) 2 Cl(NO 2 )] , the ligands are named in alphabetical order: "diammine" (for the two NH 3 groups), followed by "chlorido" (for Cl − ) and "nitrito-N" (for NO 2 attached via nitrogen). The oxidation state of platinum here is +2, denoted as "(II)" in the name. Therefore, the IUPAC name is "Diamminechloridonitrito-N-platinum(II)".
