The title racemic heterometallic dinuclear compound, [MnSn(C2H2O2S)(3)(H2O)(5)], (I), contains one main group Sn-IV metal centre and one transition metal Mn-II centre, and, by design, links the Mn-II centre to the building unit of the (Delta/Lambda) [SnL3](2-) complex anion (L is the 2-sulfidoacetate dianion). In this cluster, the Sn-IV centre of the (Delta/Lambda) [SnL3](2-) unit is coordinated by three O atoms and three S atoms from three L ligands to form an [SnO3S3] octahedral coordination environment. The Mn-II centre is in an [MnO6] octahedral coordination environment, with five O atoms from five water molecules and the sixth from the mu(2)-L ligand of the (Delta/Lambda) [SnL3](2-) unit. Between adjacent dinuclear molecules, there are many hydrogen-bond interactions of O-H center dot center dot center dot O, O-H center dot center dot center dot S, C-H center dot center dot center dot O and C-H center dot center dot center dot S types. Of these, eight pairs of O-H center dot center dot center dot O hydrogen bonds fuse all the dinuclear molecules into two-dimensional supramolecular sheets along the bc plane. Adjacent supramolecular sheets are further connected through O-H center dot center dot center dot S hydrogen bonds to give a three-dimensional supramolecular network.
