Provide a systematic name for K 2 [Mo(O)Cl 4 ].

Provide a systematic name for the following coordination complex. Here it's composed of potassium ion, and then it's made up of this complex ion which happens to be negatively charged. The 2 down here came from it, so it's 2 minus. Alright. So here we have to name the ligands that are inside the complex ion. O here would be oxo, and the chlorines would be chloro. Now remember, we name the ligands alphabetically, so chloro comes first, and there's 4 of them. So this would be tetrachloro. There's 1 oxygen, 1 oxo. So here this would be chloro oxo. Then because our transition metal is inside of a negatively charged complex ion, its ending changes to 8. Here we have to say that it would be molybdenate because we're well, yeah, molybdenate because it comes from the molybdenum element, m o. Here we have to determine its charge though. We're going to say here that it is x. Here, oxo would be, 0 well, actually, no, it'll be minus 2 because it comes from oxide, and this would be minus 1. So then we'd say x+minustimesminus2+4chlorinesminus1 equalsminus2. X minus 2 minus 4 equals minus 2. X minus 6 equals negative 2. X equals plus 4. So here let's see here. So then we'd say here this is gonna be molybdenum 4. This is the name of a complex ion portion. Oh, yes. The complex ion portion. And it's the anion portion, so it's named secondly. The potassium is the cation, so it forms the beginning of the name. Potassium, followed by this complex ion name. Remember, we're naming it like an ionic compound where we name the cation first and the anion second.

Verified step by step guidance

Identify the central metal atom in the complex, which is molybdenum (Mo).

Determine the oxidation state of the central metal. The complex is neutral, and potassium (K) has a +1 charge. The complex has two potassium ions, contributing a total of +2 charge. The ligands are four chloride ions (Cl) each with a -1 charge, and one oxo ligand (O) with a -2 charge. Set up the equation: 2(+1) + x + 4(-1) + (-2) = 0, where x is the oxidation state of Mo.

Solve the equation for x to find the oxidation state of molybdenum. This will help in determining the correct Roman numeral to use in the name.

Name the ligands in the complex. The oxo ligand is named 'oxo' and the chloride ligands are named 'chloro'.

Combine the names of the ligands with the central metal and its oxidation state to form the systematic name: Potassium tetrachloroxomolybdate(IV).
