The IUPAC name of the coordination compound [Pt(H2O)4][Zn(ox)2]

Introduction:
The given coordination compound consists of two metal ions, platinum (Pt) and zinc (Zn), and various ligands. The IUPAC name of a coordination compound is derived by considering the ligands attached to the central metal ions and their respective oxidation states.

Step 1: Identify the central metal ions
In this coordination compound, there are two central metal ions: platinum (Pt) and zinc (Zn).

Step 2: Identify the ligands and their oxidation states
Ligands are the atoms, ions, or molecules that are attached to the central metal ions. The given compound has two different ligands:
1. Aqua (H2O): The oxidation state of oxygen in water is -2, and since there are four water ligands, their total charge is -8.
2. Oxalate (ox): The oxalate ion, C2O4^2-, has a -2 charge.

Step 3: Determine the oxidation states of the central metal ions
The oxidation state of Pt can be determined by considering the charges on the ligands. Each water ligand has a charge of 0, so the oxidation state of Pt must be +2 to balance the -8 charge from the water ligands. Similarly, each oxalate ligand has a charge of -2, so the oxidation state of Zn must be +2 to balance the -4 charge from the two oxalate ligands.

Step 4: Write the complex ion and its name
The complex ion [Pt(H2O)4] has a platinum ion coordinated with four water ligands, and it has a +2 charge. The complex ion [Zn(ox)2] has a zinc ion coordinated with two oxalate ligands, and it also has a +2 charge.

The IUPAC name of the complex ion [Pt(H2O)4] is "Tetraaquaplatinum(II)".
The IUPAC name of the complex ion [Zn(ox)2] is "Bis(oxalato)zinc(II)".

Step 5: Combine the names of the complex ions
To name the whole coordination compound, we combine the names of the complex ions, with the cation (Pt) first and the anion (Zn) second.

The IUPAC name of the coordination compound [Pt(H2O)4][Zn(ox)2] is "Tetraaquaplatinum(II)bis(oxalato)zinc(II)".

Conclusion:
The IUPAC name of the coordination compound [Pt(H2O)4][Zn(ox)2] is "Tetraaquaplatinum(II)bis(oxalato)zinc(II)". This name accurately represents the central metal ions (platinum and zinc) and the ligands (water and oxalate) present in the compound, along with their respective oxidation states.
