A simple procedure is reported for the isolation of the new lacunary tungstotellurate(IV) [Te(2)W(17)O(61)](12-) (1a) in multi-gram quantities, with (125)Te and (183)W NMR spectroscopy indicating retention of the solid state structure in solution. The structurally related polyanions [Te(2)W(16)O(58)(OH)(2)](14-) (2a) and [Te(2)W(18)O(62)(OH)(2)](10-) (2b)(More)
A family of dinuclear cobalt complexes with bridging bis(dioxolene) ligands derived from 3,3,3',3'-tetramethyl-1,1'-spirobis(indane-5,5',6,6'-tetrol) (spiroH4) and ancillary ligands based on tris(2-pyridylmethyl)amine (tpa) has been synthesized and characterized. The bis(dioxolene) bridging ligand is redox-active and accessible in the (spiro(cat-cat))(4-),(More)
The combination of bridging bis-bidentate redox-active ligands derived from 3,3-bis-2-hydroxy-1,4-naphthoquinone (bhnqH2), ancillary ligands based on tris(2-pyridylmethyl)amine (tpa) and cobalt salts has afforded a new family of dinuclear cobalt complexes. Compounds of the complexes [Co2(bhnq)(tpa)2](2+) (1), [Co2(bhnq)(Metpa)2](2+) (2),(More)
Reactions between Co(OAc)2 and 2-amino-2-methyl-1,3-propanediol (ampdH2) afford a hexanuclear complex [Co6(H2O)(MeOH)(OAc)6(ampd)4] (1) and a one-dimensional coordination polymer comprised of discrete heptanuclear complexes covalently bound to mononuclear Co centers [Co8(H2O)2(OAc)7(ampd)6]n (2). While 1 is obtained under ambient reaction conditions, the(More)
The reaction of Cu(OAc)2 and Ln(OAc)3 (Ln = Gd, Tb and Dy) with 2-amino-2-methyl-1,3-propanediol (ampdH2) under solvothermal conditions has afforded a new family of isostructural octanuclear Cu4Ln4 complexes with the formula [Cu4Ln4(OAc)12(ampdH)8(OH2)2] (Ln = Gd (1), Tb (2) and Dy(3)) in good yield.
