I'm representing the charge of Pt as [Pt](1st or 2nd)TeethWhitener said:How do you work out that there will be different oxidation states? Please show your work so we can follow your reasoning.
I see. Unfortunately, there’s no way to figure it out by analyzing formal charges alone. You also need to know that Pt(IV) is the highest oxidation state you’ll see without going to heroic efforts, and also that Pt(III) is an incredibly rare oxidation state (I can’t think of a single example, but there might be some in the literature). Also, Pt(I) is a weird oxidation state that likely requires Pt-Pt bonding. All this is knowledge that you wouldn’t be able to glean from the chemical formula, but suffice it to say that if you’re working with platinum, the only oxidation states you’ll likely be dealing with are +2 and +4.jolly_math said:I'm representing the charge of Pt as [Pt](1st or 2nd)
[Pt(NH3)4I2]: overall charge is [Pt](1st) - 2
[PtI4]: overall charge is [Pt](2nd) - 4
I want to find charge of Pt so that [Pt] - 2 + [Pt] - 4 = [Pt](1st) + [Pt](2nd) + 6 = 0,
possibilities are 3 + 3, 4 + 2, etc.
A coordination compound is a type of molecule that contains a central metal atom or ion surrounded by a group of atoms or molecules called ligands. The ligands are attached to the metal atom or ion through coordinate covalent bonds.
The name of a coordination compound is determined by following a set of rules based on the type and number of ligands attached to the central metal atom or ion. The name will include the names of the ligands, followed by the name of the central metal atom or ion, and may also include any necessary prefixes or suffixes to indicate the oxidation state of the metal atom or ion.
A cation is a positively charged ion that is attracted to the negatively charged ligands in a coordination compound. An anion is a negatively charged ion that is attracted to the positively charged central metal atom or ion in a coordination compound.
The oxidation state of a central metal atom or ion in a coordination compound can be determined by considering the overall charge of the compound and the charges of the ligands. The sum of the charges must equal the overall charge of the compound, so the oxidation state of the central metal atom or ion can be calculated by subtracting the charges of the ligands from the overall charge.
Yes, coordination compounds can have multiple names depending on the rules used to name them. For example, a coordination compound can have a common name, a systematic name, and a chemical name. It is important to use the correct naming convention when referring to a specific coordination compound.
