Write names for the following coordination compounds: (a) \(\mathrm{Na}_{3}\left[\mathrm{Fe}(\mathrm{CN})_{5} \mathrm{NO}\right]\) (b) \(\left[\mathrm{CoO}\left(\mathrm{NH}_{3}\right)_{5}\right] \mathrm{Br}\) (c) \(\mathrm{Na}_{2}\left[\mathrm{NiBr}_{4}\right]\) (d) $\left[\mathrm{Rh}\left(\mathrm{H}_{2} \mathrm{O}\right)_{6}\right]\left[\mathrm{Ag}(\mathrm{CN})_{2}\right]_{3}$

First, identify the metal and its oxidation state. In this compound, the metal is iron (Fe). The ligands include five cyanides (CN-) and one nitrosyl (NO). The total charge of the coordination complex is -3, as there are three sodium ions (Na+) in the compound. Iron's oxidation state is +3, which balances the charge. The name for the coordination compound is then: Pentaamminecyanidonitrosyliron(III)

Identify the metal and its oxidation state. In this compound, the metal is cobalt (Co). The ligands include one oxide (O2-) and five ammonia (NH3) molecules. The total charge of the coordination complex is +1, as there is one bromide ion (Br-) in the compound. Cobalt's oxidation state is +3, which balances the charge. The name for the coordination compound is: Pentaammineoxocobalt(III) bromide

Identify the metal and its oxidation state. In this compound, the metal is nickel (Ni). The ligands include four bromides (Br-). The total charge of the coordination complex is -2, as there are two sodium ions (Na+) in the compound. Nickel's oxidation state is +2, which balances the charge. The name for the coordination compound is: Tetrabromidonickel(II) sodium

In this compound, there are two coordination complexes: [Rh(H2O)6] and [Ag(CN)2]. Identify the metal and its oxidation state in [Rh(H2O)6]. The metal is rhodium (Rh), and the ligands include six water (H2O) molecules. The charge of this complex is +3, which gives Rh an oxidation state of +3. The name for this coordination complex is: Hexaaquarhodium(III) Identify the metal and its oxidation state in [Ag(CN)2]. The metal is silver (Ag), and the ligands include two cyanides (CN-). The charge of this complex is -1, which gives Ag an oxidation state of +1. The name for this coordination complex is: Dicyanoargentate(I) Putting both names together, the name for the full coordination compound is: Hexaaquarhodium(III) tris(dicyanoargentate(I))
