is Sb2S5 antimony (V) sulfide or diantimony pentasulfide? I thought for molecular compounds, you use prefixes like used in diantimony pentasulfide?

I see the confusion. As a nice rule of thumb......besides Boron, use Roman numerals when dealing with metalloids. Truth be known, rules are broken so much in this area that diantimony pentasulfide, antimony pentasulfide or Antimony V sulfide would be used by most industrial chemists. Use Roman numerals if you can. Hope this helps.
