For each metal complex, give the coordination number for the metal species.
Na[Ag(CN)2
[Cd(en)Br2
Na[Ag(CN)2: The coordination number for the metal species (Ag) in this complex is 2. Just like Ag is clueless how many CN's it has, maybe it's just trying to keep its options open.
[Cd(en)Br2: The coordination number for the metal species (Cd) in this complex is 4. Cd is like a popular DJ at a party, surrounded by two bromides and two ethylenediamine (en) ligands, keeping the beats and coordination in sync.
To determine the coordination number for each metal species, we need to identify the number of ligands (atoms or molecules attached to the metal) that are bonded to the metal.
1. Na[Ag(CN)2]:
The metal species here is Ag. In the given compound, there are two CN (cyanide) ligands attached to Ag. Therefore, the coordination number for Ag is 2.
2. [Cd(en)Br2]:
The metal species here is Cd. In the given compound, there are two Br (bromine) ligands attached to Cd and one en (ethylenediamine) ligand. Hence, there are a total of three ligands attached to Cd, which gives a coordination number of 3.
Therefore, the coordination numbers for the metal species in each complex are:
1. Ag: 2
2. Cd: 3
To determine the coordination number for each metal species in the given metal complexes, we need to identify the number of ligands that are directly bonded to the central metal atom.
1. Na[Ag(CN)2]:
In this complex, the central metal atom is Ag (silver). The ligands are CN^- (cyanide) ions. To determine the coordination number, we count the number of CN^- ligands directly bonded to Ag. In this case, there are two CN^- ligands, so the coordination number is 2.
2. [Cd(en)Br2]:
In this complex, the central metal atom is Cd (cadmium). The ligands are en (ethylenediamine) and Br^- (bromide) ions. The coordination number is determined by the total number of ligands directly bonded to Cd. Here, there are two Br^- ligands that are directly bonded to Cd, so the coordination number is 2.
In summary:
- Na[Ag(CN)2]: Coordination number = 2
- [Cd(en)Br2]: Coordination number = 2
Ag is 2
Cd is 4 (en) is 2 + 2Br = 4.
