Fast Room Temperature Synthesis of the Thiostannate [Ni(2amp)3]2[Sn2S6]·9.5H2O: Crystal Structure and Properties

Fast Room Temperature Synthesis of the Thiostannate [Ni(2amp)3]2[Sn2S6]·9.5H2O: Crystal Structure and Properties
Wolfgang Bensch, Jessica Hilbert, Christian Näther
The new compound [Ni(2amp)3]2[Sn2S6]·9.5H2O (1) was obtained at room temperature using Na4SnS4·14H2O and [Ni(2amp)3][ClO4]2 [2amp = 2-(aminomethyl)pyridine] or [Ni(en)3]Cl2·2H2O as starting materials. The synthesis is fast and crystals grew within 1 d. The two unique anions and cations are embedded in an extended water cluster network and an extensive hydrogen bonding network is formed. The complexes are arranged to form intermolecular π–π interactions between neighboring 2amp ligands. A Hirshfeld surface analysis yields a detailed picture about the intermolecular interactions. Heating the compound up to about 100 °C the crystal water molecules are removed and a new crystalline material is formed. Storing the dehydrated sample in a water atmosphere leads to reformation of the title compound.
