Comparison of simulated PDF of 10 Å fibroferrite, M–T–M–T chain, sarmientite, maxwellite, césarferreiraite, and scorodite with experimental PDF of ferric arsenate (digitized from Mikutta et al. 2014). Simulations performed by replacing S by As in fibroferrite, V by Fe in ladder-like double VAsO4 chains (M–T–M–T) without changing the crystal-structure parameters. Vertical scales are identical for all.
