The [Sn2S6]4– Anion Acting as Tetradentate Linker: ­Solvothermal Synthesis and Selected Properties of {[TM(phen)2]2Sn2S6} and {[TM(phen)2]2Sn2S6}·phen·H2O (TM = Fe, Co)

Abstract

AbstractFour new compounds with the [Sn2S6]4– anion acting as tetradentate ligand to metal cations of [TM(phen)2]2+ complexes (TM = Fe, Co; phen = 1,10‐phenanthroline) were synthesized under solvothermal conditions. The compounds are rare cases where Fe2+/Co2+ cations form bonds to sulfide anions of a thiometallate anion. In the structures of the compounds the {[TM(phen)2]2Sn2S6} molecule is the main structural motif. The phen ligands of neighboring molecules are oriented in a way that off‐center parallel stacking results leading to weak intermolecular interactions. In two of the four compounds a free phen molecule is trapped between adjacent {[TM(phen)2]2Sn2S6} moieties and an additional H2O molecule is located near the two nitrogen atoms of the free phen molecule. The Hirshfeld surface analysis yields a variety of weak intermolecular interactions which may be regarded as essential for the packing arrangement of the different constituents and the stability of the compounds.
