For the following complex ion: [Ru(NH3)5Br]2+?

Question

name the ion
give its coordination number
predict its most likely shape (or shapes).

Answer 1

bromopentaammineruthenium (II)

Coordination # is 6

Likely structure is octahedral


Note: Sorry for the typo, it should have read (III) as it is in the +3 oxidation state

Answer 2

The above answer is almost correct, except that the oxidation state is +3, and so there should be a (III) after the ion.
