摘要
Two novel octahedral rhenium(III) chalcocyanohydroxo cluster complexes [Ni(en)3]2[Re6S8(CN)4(OH)2]路5.5H2O (1) and [Ni(en)3]2[Re6Se8(CN)4(OH)2]路10H2O (2) have been prepared by reaction of cluster complexes Cs1.68K2.32[Re6S8(CN)4(OH)2]路2H2O and Cs2.75K1.25[Re6Se8(CN)4(OH)2]路H2O with NiCl2 and en (en = ethylenediamine) in aqueous ammonia solutions. Both compounds were characterized by IR-spectra, elemental analysis, EDS, DTA and single-crystal X-ray analysis. Compound 1 crystallizes in the monoclinic space group C2/c, while compound 2 refers to the triclinic space group P-1. The structures of both compounds consist of discrete ions [Ni(en)3]2+, [Re6Q8(CN)4(OH)2]4鈭?/sup> and water molecules of crystallization that are bonded by a network of hydrogen bonds. In the structure of 1 the [Re6S8(CN)4(OH)2]4鈭?/sup> anions are bound to each other via OH鈰疦C hydrogen interactions (O鈰疦 distance is 2.950(10) 脜), thus forming a linear chains running along the c axis.
