Abstract
- Abstract: A new compound 1 (phen=phenanthroline) has been synthesized under hydrothermal conditions and characterized by IR, TG analysis and single-crystal X-ray diffraction. The study of the magnetic property of compound 1 exhibits the presence of antiferromagnetic interactions. Compound 1 crystallizes in the monoclinic system, space group P21/c, a =21.843(4)Å, b =16.566(3)Å, c =21.025(4)Å, α =90°, β =100.26(3)°, γ =90°, V =7486(3)Å3, Z =2. The basic building unit in compound 1 is the [PMo12V2O42] cluster. The most remarkable structural feature of 1 is that there exist two distinct [PMo12V2O42] clusters. One is covalently linked by [Co(phen)2] complexes to form 2D covalent layer, the other supports two [Co(phen)2(H2O)] complexes forming a 2D supramolecular network. Such two different kinds of layers are further stacked to form a novel 3D supramolecular framework. [Copyright &y& Elsevier]
