Single-Crystal to Single-Crystal Reversible Transformations Induced by Thermal Dehydration in Keggin-Type Polyoxometalates Decorated with Copper(II)-Picolinate Complexes: The Structure Directing Role of Guanidinium
Three new hybrid inorganic-metalorganic compounds containing Keggin-type polyoxometalates, neutral copper(II)-picolinate complexes and guanidinium cations have been synthesized in bench conditions and characterized by elemental analysis, infrared spectroscopy and single-crystal X-ray diffraction: the isostructural [C(NH2)3]4[{XW12O40}{Cu2(pic)4}]·[Cu2(pic)4(H2O)]2·6H2O [X = Si (1), Ge (3)] and ...
متن کاملp-tert-Butylthiacalix[4]arene-supported high-nuclearity {Co24M8} (M=Mo or W) nanospheres and the hybrids with Keggin polyoxometalates.
Two hybrid assemblies (3 and 4) with two kind of nanoscaled cluster units, the spherical [Co(24)(TC4A)(6)(MO(4))(8)Cl(6)](2+) cation (1 and 2) and Keggin-type [PM(12)O(40)](3-) anion (M = Mo (1/3), W (2/4)), were solvothermally prepared and characterized, in which the spherical units are constructed by six Co(4)-p-tert-butylthiacalix[4]arene (Co(4)-TC4A) SBUs linked by eight MO(4) tetrahedrons ...

Chapter 1. Synthesis and Characterization of a Novel Class of Dicopper(I) Bis(carboxylate)-Bridged Complexes The syntheses, spectroscopic properties, crystal and molecular structures, and bonding of several dicopper(I) bis(carboxylate)-bridged complexes are described in which the bridging dicarboxylate ligand is the dianion of m-xylylenediamine bis(Kemp's triacid imide) (H2XDK, 1). A sterically...
متن کاملMonolacunary Keggin polyoxometalates connected to ten 4d or 4f metal atoms.
The rational self-assembly of mono-lacunary Keggin clusters with 4d and 4f metal salts via a conventional method has yielded two novel polyoxometalate-based 4d-4f heterometallic compounds containing lacunary Keggin anions connected to ten metal atoms: {[Ag{Ag2(H2O)4}{Ln(H2O)6}2H ⊂ {SiW11Ln(H2O)4O39}2]·nH2O (Ln = Ce and n = 7 for 1, Ln = Pr and n = 3 for 2). Their structures were determined by s...
