Two novel octahedral rhenium(III) selenocyanide cluster complexes [( n Bu) 4 N] 2 Ni(H 2 O) 5 [Re 6 Se 8 (CN) 6 ]·2H 2 O ( 1 ) and [( n Bu) 4 N] 2 Mn(H 2 O) 4 [Re 6 Se 8 (CN) 6 ]·2H 2 O ( 2 ) have been prepared by the reaction of K 4 [Re 6 Se 8 (CN) 6 ]·3.5H 2 O, ( n Bu) 4 NBr and Ni(OAc) 2 (or MnSO 4 ) in aqueous solution. The complexes have been structurally solved in the orthorhombic unit cell Pbca with parameters: a = 19.393(2), b = 17.292(2), c = 37.255(4) Å for 1 , and a = 19.518(4), b = 17.488(3), c = 37.997(5) Å for 2 . The cluster anions and M 2+ form ionic pairs {M(H 2 O) n [Re 6 Se 8 (CN) 6 ]} 2− that are packed in the solid state with n ‐tetrabutylammonium cations. Coordinated and solvate water molecules as well as the nitrogen atoms of the anions form a network of hydrogen bonds in the structures. These compounds are isomorphous, although the coordination environments of the metal cations differ. (© Wiley‐VCH Verlag GmbH, 69451 Weinheim, Germany, 2002)
