Abstract

A nickel-1,10-phenanthroline complex supported on an octamolybdate, [(Ni(phen)₂)₂ (ξ-Mo₈O₂₆)], has been hydrothermally synthesized with MoO₃, H₂MoO₄, Ni(OAc)₂ • 6H₂O and 1,10-phenathroline (1,10-phen) as raw materials. The crystals of the compound belong to monoclinic P2₁/n space group, a = 1.2952(2), b = 1.6659(10), c = 1.3956(12) nm, β = 106.273(8)°, V = 2.8906(5) nm³, Z = 2.5604 observable reflections (l >2σ(l)) were used for structure resolution and refinements to converge to final R₁ = 0.0414, wR₂ = 0.0815. The result of structure determination shows that the compound contains octamolybdate possessing a novel structure type (named as ξ-isomer). The feature of ξ-[Mo₈O₂₆]^4- is that is composed of Mo₆O₆ ring and two Mo₆ octahedra located at cap positions on opposite faces. The Mo₆O₆ ring contains two octahedral and four trigonal-bipyramidal Mo^VI atoms. Each ξ-[Mo₈O₂₆]^4- unit is bonded with two [Ni(phen)₂]²⁺ through terminal oxygen atoms of octahedral and neighbouring trigonal-bipyramidal Mo atom in the Mo₆O₆ ring. IR and UV-Vis spectra of the compound were measured and its electronic structure was studied by EHMO method.
