Am I allowed to multiply the subscripts outside the parenthesis after doing this specific question's criss cross?

I did the criss cross method between #Ca^(+2) and [NO_3]^-1# and I got #Ca [NO_3]_2#. Can I make this #Ca [N_2O_6]#?

In any of its applications like getting molar mass etc we have to open the parenthesis, but the correct notation is #"Ca"("NO"_3)_2# because it means that two nitrates are attached to calcium cation, whereas #"CaN"_2"O"_6# is not the same structure.

So #"Ca"("NO"_3)_2# is correct.
