Cuboidal Mo3S4 and Mo3NiS4 Complexes Bearing Dithiophosphates and Chiral Carboxylate Ligands: Synthesis, Crystal Structure and Fluxionality
Wiley (2011-02)New triangular Mo and W cluster complexes incorporating (S)-lactic acid (HLac), [Mo3S4(μ-Lac)(dtp)3(py)] (1) and [W3S4(μ-Lac)(dtp)3(py)] (2), were prepared [dtp = (EtO)2PS2]. Analogous synthetic procedures were adapted for ... -
Dual setereocontrolled alkylation of aldehydes with polystyrene-supported nickel complexes derived from a-amino amides
Royal Society of Chemistry (2015-01)Nickel(II) complexes derived from α-amino amide ligands anchored to gel-type and monolithic polymers act as efficient catalysts for the enantioselective addition of dialkylzinc reagents to aldehydes. Similar to the analogous ... -
Isolation of a New Cs-Symmetrized Mo3(μ3-S)(μ-S)(μ-S2)2 Structural Type Through Complementary Association with a Cubane-Type Mo3NiS4 Cluster
Wiley (2012)A new cluster of formula {[Mo3(μ3-S)(μ-S)(μ-S2)2(dtp)3(μ-OAc)][Mo3NiS4(dtp)3(μ-OAc)(CH3CN)]} (1; dtp = diethyl dithiophosphate; OAc = acetate) comprising the novel Cs-symmetrized Mo3(μ3-S)(μ-S)(μ-S2)2 structural type ... -
Novel Family of Nickel (II)-Cornered Molecular Cages with Bis-NHC Bridging Groups
Universitat Jaume I (2016-07-21)Metal-directed self-assembly has been widely studied in the last decades since Lehn and co-workers demonstrate the spontaneous self-assembly of dinuclear helicates from 2,2’-bipyridine and copper(I). Thereafter, a ... -
Rotation-Invariant Deep Embedding for Remote Sensing Images
Institute of Electrical and Electronics Engineers (2021-06-28)Endowing convolutional neural networks (CNNs) with the rotation-invariant capability is important for characterizing the semantic contents of remote sensing (RS) images since they do not have typical orientations. Most of ... -
Structural characterization and colour of Ni3VxP2−xO8 (0 ≤ x ≤ 2) and Ni2VyP2−yO7 (0 ≤ y ≤ 2) materials
Elsevier (2017)Structural characterization of Ni3VxP2−xO8 (0 ≤ x ≤ 2) and Ni2VyP2−yO7 (0 ≤ y ≤ 2) compositions was made and colour parameters of these materials measured. Ni(II) diphosphate and divanadate crystalline phases are not stables ... -
Variations in vanadium, nickel and lanthanoid element concentrations in urban air
Elsevier (2010)The emission of trace metal pollutants by industry and transport takes place on a scale large enough to alter atmospheric chemistry and results in measurable differences between the urban background of inhalable particulate ...
