Question

what is the name for Mn(ClO3)7

Answer 1

Manganese (VII) chlorate

Answer 2

You could also name it heptachloratomanganese(VII), if you want to name it as a complex.

Answer 3

Which is probably more accurate, since it isn't really an ionic compound, not with Mn in the +7 oxidation state.

Answer 4

@carl_pham: are u answering this on the basis of the 1st answer ? because the 1st one is wrong..i had this question in a quiz and when i tried that answer, it proved to be wrong.

Answer 5

I don't see anything wrong with "manganese (VII) chlorate," if you're being allowed to name it as an ionic compound. If you are submitting to an electronic system, be sure you double-check your spelling, spacing, whether you use capital I for Roman numeral or lower-case l, et cetera.

As I said, it might possibly be better to name it as a complex, since if this compound exists -- I actually kind of doubt it, since there would be tremendous steric hindrance among all those ClO3- anions -- there will be coordinate covalent bonds between the manganese and the oxygen atoms on the chlorate anions.

To name something as a complex, you give the ligands names as a prefix, followed by the metal name and the charge in Stock notation. That, as I said, gives you "heptachloratomanganese(VII)".

But naming complexes of transition metals is something you typically only do in the second semester of college general chemistry, or in the first part of an upper-division inorganic chemistry class. I'm not sure where you are, so I'm not sure whether you would be doing this. As a rule, in high-school or first-semester general chemistry, you would probably be expected to name this compound as an ionic compound, because you're usually told metal + nonmetal = ionic compound, full stop. That's not strictly true, but the nuances are usually explained later.

Mind you, I don't think this is a tip-top question. I doubt this complex actually exists, and whether one should name it as an ionic compound or metal complex is unclear.
