✦ Synopsis

The new compound [Co(tren)(trenH 2 )] 2 [{Co(tren)} 2 -V 15 Ge 6 O 42 S 6 (H 2 O)]•9H 2 O [1, tren = tris(2-aminoethyl)amine] has been obtained under solvothermal conditions and features the unique thiogermanatovanadatopolyoxoanion [V IV 15 Ge IV 6 O 42 S 6 (H 2 O)] 12-as the main structural motif. Compound 1 crystallizes in the monoclinic space group P2 1 /c with a = 15.4711(2), b = 26.4031(4), c = 26.7213(4) Å, V = 10874.2(3) Å 3 , and Z = 4. The [V 15 Ge 6 O 42 S 6 (H 2 O)] 12-cluster anion displays the spin topology reported for the molecular magnets [V IV 15 As III 6 O 42 (H 2 O)] 6-and [V IV 15 Sb III 6 O 42 ] 6-and [a
