Abstract

Applying a new synthetic approach in which transition metal complexes and a thiogermanate source are in different liquid phases resulted in crystallization of three new compounds with the adamantane-like [Ge4S10]4– anion at room temperature. In the crystal structure of [Ni(cyclam)]3[Ni(cyclam)(H2O)2][Ge4S10]2·21H2O (I, cyclam = 1,4,8,11-tetraazacyclotetradecane), the two different Ni2+-centered complexes and two unique [Ge4S10]4– anions are joined by H-bonding interactions with a water cluster composed of condensed pentameric and hexameric rings. The compound {[Mn(2,2′-bipy)2(H2O)]2Ge4S10}·3H2O (II, bipy = bipyridine) also contains the [Ge4S10]4– anion, which is expanded by two Mn2+-centered complexes through Mn–S–Ge bonds. The aqua ligand of the Mn2+-centered complex is involved in O–H···S H-bonding to a terminal S atom of the anion with formation of a chain of {[Mn(2,2′-bipy)2(H2O)]2Ge4S10} molecules. In the structure of [Fe(2,2′-bipy)3]2[Ge4S10]·10H2O (III), the [Fe(2,2′-bipy)3]2+ complexes are arranged to form channels that host the thiogermanate anions. Between the 2,2′-bipy ligands of the complexes π–π interactions are observed. The water molecules of crystallization form two different types of water clusters.
