Abstract

The new compound [Co(tren)(trenH2)]2[{Co(tren)}2V15Ge6O42S6(H2O)]·9H2O [1, tren = tris(2‐aminoethyl)amine] has been obtained under solvothermal conditions and features the unique thiogermanatovanadatopolyoxoanion[VIV15GeIV6O42S6(H2O)]12– as the main structural motif. Compound 1 crystallizes in the monoclinic space group P21/c with a = 15.4711(2), b = 26.4031(4), c = 26.7213(4) Å, V = 10874.2(3) Å3, and Z = 4. The [V15Ge6O42S6(H2O)]12– cluster anion displays the spin topology reported for the molecular magnets [VIV15AsIII6O42(H2O)]6– and [VIV15SbIII6O42]6– and therefore represents a new member of the {V15E6} family, which has allowed us to study the magnetic exchange interactions between the vanadyl (d1) groups of the geometrically frustrated central V3 triangle, which is sandwiched between strongly antiferromagnetically coupled V6 hexagons. The cluster shell is expanded by two {Co(tren)}2+‐based complexes through Co–S bonds, which reduce the high negative charge of the anion. The Co2+ ions in the [Co(tren)(trenH2)]4+ countercations are coordinated to one tetradentate tren and a monodentate, doubly protonated tren ligand.
