The structures of three novel octahedral rhenium cluster compounds [Re 6 S 8 (CN) 2 (py) 4 ]·H 2 O ( 1 ), [Re 6 S 8 (CN) 2 (4-Mepy) 4 ] ( 2 ), [Re 6 S 8 (CN) 2 (4-Mepy) 4 ]·4-Mepy ( 3 ) (py = pyridine, 4-Mepy = 4-methylpyridine) are determined by X-ray crystallography. Crystal data are: C 2/ m space group, a = 14.813(1) Å, b = 14.772(1) Å, c = 9.2122(6) Å, β = 119.085(2)°, V = 1761.7(2) Å 3 , d x = 3.318 g/cm 3 , R = 0.0585 ( 1 ); I 4 1 / amd space group, a = 16.0018(3) Å, c = 14.7186(5) Å, V = 3768.81(16) Å 3 , d x = 3.169 g/cm 3 , R = 0.0489 ( 2 ); P 2 1 / c space group, a = 9.0452(4) Å, b = 15.8065(7) Å, c = 15.2951(6) Å, β = 103.700(2)°, V = 2124.57(16) Å 3 , d x = 2.957 g/cm 3 , R = 0.0245 ( 3 ). Molecular cluster complexes interact via π-π stacking affording 3D frameworks in 1 and 2 and chains in 3 .
