N2 - Two novel rhenium cluster compounds, K4[Re6S 8(OH)6]·8H2O (1) and K 4[Re6Se8(OH)6]·8H 2O (2), containing octahedral cluster chalcogenide anionic complexes [Re6Q8(OH)6]4- with terminal hydroxo ligands have been synthesized by the reaction of Re6Q 8Br2 (Q = S, Se) with molten KOH. Two chalcohalide compounds, one known (Cs4[Re6S8Br 6]·2H2O, 3) and another new (Cs3[Re 6Se8Cl6]·2H2O, 4), were prepared by reactions of 1 and 2 with CsX and HX (X = Br, Cl) in an aqueous solution. Compounds 1, 2, and 4 have been characterized by the single-crystal X-ray diffraction method. Compounds 1 and 2 are crystallized in triclinic space group P1 with one formula unit in the cell of dimensions a = 8.4936(8) Å, b = 8.9101(11) Å, c = 10.5940(13) Å, α = 77.935(11)°, β = 75.933(9)°, γ = 71.244(10)°, V = 728.9(1) Å3 (compound 1) and a = 8.613(1) Å, b = 8.996(1) Å, c = 10.057(1) Å, α = 78.587(2)°, β = 77.811(2)°, γ = 71.728(2)°, V = 715.9(2) Å3 (compound 2). Compound 4 crystallizes in the monoclinic space group P21/n with two formula units in the cell of dimensions a = 9.819(3) Å, b = 12.925(4) Å, c = 11.756(4) Å, β = 113.38(3)°, V = 1369.6(8) Å3. Compounds 1 and 2 display luminescent properties.
