In the title compound, C21H26O2SSe, the S atom adopts a pyramidal geometry (bond-angle sum = 304°) and the n-butyl chain shows an extended conformation. An intramolecular C—HO hydrogen bond closes an S(8) ring. In the crystal, inversion dimers are formed with molecules linked by pairs of O—HO=S hydrogen bonds, generating R22(14) loops. Weak C—HO interactions also occur.

The trinuclear title compound, [Fe3(C3H6S2)2(CO)7], is a mixed-valent FeI/FeII complex and crystallizes with two molecules of similar configuration in the asymmetric unit. The three Fe atoms in each molecule display a bent arrangement [Fe—Fe—Fe = 156.22 (4) and 157.06 (3)°]. Both outer FeI atoms are six-coordinated in a distorted ocahedral coordination geometry defined by the bridging FeII atom, three carbonyl C atoms and two bridging S atoms. The coordination number of the central FeII atom is seven and includes bonding to the two outer FeI atoms, four bridging S atoms and one carbonyl C atom. The resulting coordination polyhedron might be described as a highly distorted monocapped trigonal prism. In the crystal packing, the molecules exhibit a chain-like arrangement parallel to [100] and [001], and the resulting layers are stacked along [010]. The cohesion of the structure is dominated by van der Waals interactions.
