A novel 1D chain compound constructed from copper-complex fragments-substituted dilacunary β-octamolybdate units and saturated β-octamolybdate clusters

A copper-complex fragments-substituted β-octamolybdate, K2[{Cu(phen)}4Mo6O22][Mo8O26] · 2H3O (1) (phen = 1,10-phenanthroline), has been hydrothermally synthesized and structurally characterized for the first time. Compound 1 is constructed from transition-metal-substituted dilacunary β-octamolybdate fragment [{Cu(phen)}4Mo6O22] and [β-Mo8O26]4− cluster to form one-dimensional (1D) linear chain. Furthermore, magnetic measurements show weak ferromagnetic interactions for compound 1.
