Hexarhenium(III) clusters [Re6(μ3-E)8(CN)6]4− (E2− = S2−, Se2−, Te2−) are luminescent at room temperature with the emission quantum yield and lifetime in the order E2− = Se2− > S2− >> Te2− both in acetonitrile and water.

Hexadentate cluster anions [Re₆S₈(CN)₆]⁴⁻ coordinate to Mn(II) centers to give a neutral 3D coordination network topologically related to the structure of Prussian Blue; the residual space is filled with isopropyl alcohol molecules, both ligated to Mn(II) and guest-solvated.
