Crystals of tris(3‐mercapto‐1,3‐diphenyl‐2‐propen‐1‐onato)cobalt(III), Co(C 15 H 11 OS) 3 , C 45 H 33 CoO 3 S 3 , are monoclinic, P 2 1 / a , a = 19.33, b = 11.02, c = 18.13 Å, all ±0.3%, β = 93°0′±15′; D obs = 1.346 (5) Mg m −3 at 293 K giving Z = 4 and D x = 1.338 Mg m −3 . Multiple twinning results from fortuitous pseudo‐orthorhombic and pseudo‐hexagonal ( a / b ≃√3) twin‐lattice symmetry around c [001].
