Abstract:

A novel inorganic-organic hybrid based on isopolyanion, {[Cu2(phen)2(μ-ox)][H2Mo8O26]}·4EtOH·Et2O(1)(phen=phenanthroline, ox=oxalate), was synthesized under open-air mild reaction conditions, and characterized by elemental analysis, IR, ICP, TG and single crystal X-ray diffraction analysis. The crystal structure belongs to triclinic system with space group Pī and cell parameters: a=1.1075(5) nm, b=1.1608(5) nm, c=1.3333(5) nm, α=91.683(5)°, β=113.996(5)°, γ=112.170(5)°, V=1.4159(10) nm3, Mr=2017.44, Z=1, Dc=2.366 g/cm3 and F(000)=980.0. The structure of hybrid 1 is a 1D chain constructed of alternating octamolybdate isopolyanions [β-(Mo8O26)4–] and oxalato- bridged dinuclear copper complex cations [Cu2(phen)2(μ-ox)]2+. Ultimately, a 3D supramolecular network was formed by hydrogen bond interactions among the adjacent chains. The result shows that hybrid 1 is the first example of inorganic-organic hybrid constructed from isopolyanion and oxalato-bridged dinuclear copper complex fragment (CCDC No. 665101).
