Schematic illustration of the cubanes studied by Patzke and co-workers: {Co₄(OR)₄} (left, Evangelisti et al. (2013)) and {Co3Ln(OR)4} (middle, Evangelisti et al. (2015)) (R = hmp, and Ln = Er, Tm, Yb, Ho), and the recently published third generation [${\text{Co}}_4^{\text{III}}$((dpy(OH)(O))₄)(OAc)₂(OH₂)₂]²⁺ (right, Song et al. (2017)). Extension to the color code: lime – erbium, thulium, ytterbium or holmium. Reproduced from geometrical data published by Evangelisti et al. (2013) (left) Evangelisti et al. (2015) (middle), and Song et al. (2017) (right).
