Three novel supramolecular assemblies constructed from polyoxometalate and crown ether building blocks, [(DB18C6)Na(H(2)O)(1.5)](2)Mo(6)O(19).CH(3)CN, 1, and [(Na(DB18C6)(H(2)O)(2))(3)(H(2)O)(2)]XMo(12)O(40).6DMF.CH(3)CN (X = P, 2, and As, 3; DB18C6 = dibenzo-18-crown-6; DMF = N,N-dimethylfomamide), have been synthesized and characterized by elemental(More)
Two novel compounds, [Co(4,4'-bipy)(H(2)O)(4)](4-abs)(2).H(2)O (1) and [Mn(4,4'-bipy)(H(2)O)(4)](4-abs)(2).2H(2)O (2) (4,4'-bipy = 4,4'-bipyridine; 4-abs = 4-aminobenzenesulfonate), have been synthesized in aqueous solution and characterized by single-crystal X-ray diffraction, elemental analyses, UV-vis and IR spectra, and TG analysis. X-ray structural(More)
The spherical Lindquist type polyoxometalate, Mo(6)O(19)(2)(-), has been used as a noncoordinating anionic template for the construction of novel three-dimensional lanthanide-aromatic monocarboxylate dimer supramolecular networks [Ln(2)(DNBA)(4)(DMF)(8)][Mo(6)O(19)] (Ln = La 1, Ce 2, and Eu 3, DNBA = 3,5-dinitrobenzoate, DMF = dimethylformamide). The title(More)
The title complex, [Gd(2)(C(3)H(7)NO(2))(4)(H(2)O)(8)](ClO(4))(6), contains centrosymmetric dimeric [Gd(2)(Ala)(4)(H(2)O)(8)](6+) cations (Ala is alpha-alanine) and perchlorate anions. The four alanine molecules act as bridging ligands linking two Gd(3+) ions through their carboxylate O atoms. Each Gd(3+) ion is also coordinated by four water molecules,(More)
Three novel polyoxometalate derivatives decorated by transition metal complexes have been hydrothermally synthesized. Compound 1 consists of [PMo(VI)(6)Mo(V)(2)V(IV)(8)O(44)[Co (2,2'-bipy)(2)(H(2)O)](4)](3+) polyoxocations and [PMo(VI)(4-)Mo(V)(4)V(IV)(8)O(44)[Co(2,2'-bipy)(2)(H(2)O)](2)](3-) polyoxoanions, which are both built on mixed-metal tetracapped(More)
