Drawing complex ions OCR

Hi when drawing complex ions in the F325 exam, does anybody know if it is acceptable to use simplified diagrams as opposed to drawing out every single atom.

i.e. on June 2010 F325(Q6diii), the mark scheme only shows "simplified diagrams". However on other mark schemes, all the individual atoms of the ligands are shown?

Mark scheme - http://www.ocr.org.uk/Images/61528-mark-scheme-unit-f325-equilibria-energetics-and-elements-june.pdf

Can anybody shed any light?

Thank you!

It is the arrangements that matter, you can just show the bidentate ligand as a line with no extra detail beyond the possible arrangements. The Q is about stereoisomerism rather than your ability to draw displayed formulae.

If it comes up, make your answer look like this mark scheme.
