Abstract

A new compound [Zn(phen)2]2[ [image omitted]][Zn(phen)2(H2O)]2[ [image omitted]] · 7H2O (phen = phenanthroline) has been synthesized under hydrothermal conditions and characterized by IR, TG analysis and single-crystal X-ray diffraction. Compound 1 crystallizes in the monoclinic system, space group P21/C, a = 21.609(4) Å, b = 16.537(3) Å, c = 21.279(4) Å, α = 90°, β = 100.25(3)°, γ = 90°, V = 7483(3) Å3, Z = 2. The basic building unit in 1 is the [PMo8V6O42] cluster. The most remarkable structural feature of 1 is that there exist two distinct [PMo8V6O42] clusters. One is covalently linked by [Zn(phen)2] complexes to form a 2D covalent layer, the other supports two [Zn(phen)2(H2O)] complexes forming a discrete bisupporting structure. It is interesting that discrete bisupporting clusters locate in the space of two adjacent covalently layers to form a 3D supramolecular framework.
