Abstract
The reaction of MoO3, H2MoO4 and Ni(Ac)2·6H2O with 1,10-phenanthroline by a hydrothermal method furnishes the discrete cluster [Ni(phen)3]2[Mo8O26]·2H2O (1). The structure of 1 is triclinic, space group (Pl̄), a = 11.4965(10), b = 11.6829(13), c = 15.1518(15) Å α = 83.032(8), β = 71.557(7), γ = 78.319(7)°, R = 0.0433 for 7397 observed [I > 2<σ(I)] reflections. The crystallographically determined solid state structure of 1 shows that the cluster consists of two complex cations, one cluster anion [Mo8O26]4- and two water molecules of crystallization. Each nickel ion is coordinated by six nitrogen atoms from three phenanthroline ligands, forming a distorted octahedron, and the anion has a β-configuration formed by eight edge-sharing MoO6 octahedra. Compound 1 was characterized by means of elemental analysis, IR spectra and TGA analysis. (C) 2000 Editions scientifiques et medicales Elsevier SAS.
