Synthesis and structural and spectroscopic characterization of a complex between Co(II) and imino-bis(methylphosphonic acid): Gaining insight into biologically relevant metal-ion phosphonate interactions or looking at a new Co(II)-organophosphonate material?
(2002)
Cobalt is an essential metal ion involved in key biomolecules, regulating processes in human physiology. As a metal ion, Co(II) assumes forms, which are dictated by the nature of organic binders in biological fluids, and ...
A2Bi8Se13 (A = Rb, Cs), CsBi3.67Se6, and BaBi2Se4: New ternary semiconducting bismuth selenides
(2001)
Rb2Bi8Se13 (I), Cs2Bi8Se13 (II), CsBi3.67Se6 (III), and BaBi2Se4 (IV) were synthesized by direct combination reactions of the A/Se (A = Rb, Cs, Ba) and Bi2Se3 at ≥650 °C. Their structures were determined by single-crystal ...
Synthesis, characterization, and study of octanuclear iron-oxo clusters containing a redox-active Fe4O4-cubane core
(2008)
A one-pot synthetic procedure yields the octanuclear FeIII complexes Fe8(μ4-O)4(μ-pz*) 12X4, where X = Cl and pz* = pyrazolate anion (pz = C3H3N2-) (1), 4-Cl-pz (2), and 4-Me-pz (3) or X = Br and pz* = pz (4). The crystal ...
CsMBi3Te6 and CsM2Bi3Te7 (M = Pb, Sn): New thermoelectric compounds with low-dimensional structures
(2002)
The new materials CsPbBi3Te6 nad CsPb2Bi3Te7 were discovered through reactions of CsBi4Te6 with PbTe, whereas the isostructural materials CsSnBi3Te6 and CsSn2Bi3Te7 were discovered through corresponding reactions with SnTe. ...
Formation of oligotriazoles catalysed by cucurbituril
(2002)
The catalytic activity of cucurbituril in 1,3-dipolar cycloadditions has been applied to the synthesis of oligotriazoles.
Correlations of synthetic, spectroscopic, structural, and speciation studies in the biologically relevant Cobalt(II) - Citrate system: The tale of the first aqueous dinuclear Cobalt(II) - Citrate complex
(2003)
Synthetic efforts targeting soluble species of Co(II) with the low molecular mass physiological ligand citric acid led to the isolation of the first dinuclear complex [Co2(C6H5O7)2 (H2O)4]2-, at pH ∼5, in the form of its ...
Synthesis and aqueous solution characterization of amphiphilic diblock copolymers containing carbazole
(2002)
A series of near-monodisperse diblock copolymers of 2-(N-carbazolyl)ethyl methacrylate and 2-(dimethylamino)ethyl methacrylate (DMAEMA) of relatively low molecular weights (2600-24,000 g mol-1) were synthesized by group ...
Controlled synthesis of homopolymers and block copolymers based on 2-(acetoacetoxy)ethyl methacrylate via RAFT radical polymerisation
(2003)
Reversible addition-fragmentation chain transfer (RAFT) radical polymerisation enables to synthesise well-defined homopolymers and block copolymers based on 2-(acetoacetoxy)ethyl methacrylate, which are capable to strongly ...
Thermoelectric properties and site-selective Rb+/K+ distribution in the K2-xRbxBi8Se13 series
(2003)
β-K2Bi8Se13 possesses promising thermoelectric properties whereas Rb2Bi8Se13 does not. The formation of solid solutions between these two compounds was attempted to study the alkali metal distribution in the structure and ...
Synthesis, Crystallographic Studies, and Characterization of K 2Bi8Se13-xSx Solid Solutions
(2003)
The detailed crystal structures of selected members of solid solutions of the thermoelectric compounds K2Bi8Se13-xS x with x = 4, x = 6 and x = 10 were determined. The purpose of this study was to understand the nature of ...
