The crystal structure of Cs2W3O10 (a=16.103, c=10.169 Å,
$$I\bar 4$$
, Z=120/11) was determined from three-dimensional X-ray diffraction data (CAD-4 automatic diffractometer, 1612 reflections, R=0.044). The structure has an AB2O6 defective pyrochlore motif in which some of the groups consisting of four W...... hiện toàn bộ
Method for constructing the radial distribution curvesSpringer Science and Business Media LLC - Tập 48 - Trang 262-266 - 2007

A method for constructing the model radial distribution curves of electron density is described. The utility of this technique for the refinement of structure and phase composition for highly disperse materials is demonstrated by reference to several examples.
Organic radicals in natural apatites according to EPR data: Potential genetic and paleoclimatic indicatorsSpringer Science and Business Media LLC - Tập 51 - Trang 471-481 - 2010

In a group of natural marine apatites Ca5(PO4)3(F, OH), organic ĊH3, ĊH2—R, HOĊHR, (CH3)2—ĊR, and —Ċorg radicals are identified by EPR. The relation between the EPR spectra of the observed organic radicals, the valence form, and the structural location of impurity vanadium ions (V4+ (VO2+) on the Ca2+ II site or V5+ (VO4)3- → (PO4)3-) is established. The structure of organic radicals correlates wi...... hiện toàn bộ
CHARGE TRANSFER COMPLEXES OF NITRO DERIVATIVES OF 9,10-PHENANTHRENEQUINONE WITH ANTHRACENE. CRYSTAL AND MOLECULAR STRUCTURES OF THE (1:1) COMPLEX OF 2,4,7-TRINITRO- 9,10-PHENANTHRENEQUINONE WITH ANTHRACENESpringer Science and Business Media LLC - Tập 62 - Trang 137-146 - 2021

Charge transfer complexes (CTCs) are obtained by the interaction of 9,10-phenanthrenequinone nitro derivatives with anthracene. By electron spectroscopy it is established that the acceptor properties of the former increase with increasing number of nitro groups and depend on their position. 1,3,6-Trinitro-9,10-phenanthrenequinone, which forms with anthracene a CTC with a charge transfer band near ...... hiện toàn bộ
X-ray photoelectron and X-ray emission study of the electronic structure of hexanuclear Mn(II,III) pivalate complexesSpringer Science and Business Media LLC - Tập 58 - Trang 1166-1172 - 2017

The electronic structure of hexanuclear Mn(II,III) pivalate complexes with tetrahydrofuran and isonicotinamide are studied by X-ray photoelectron spectroscopy and X-ray emission spectroscopy. It is shown that when isonicotinamide substitutes for tetrahydrofuran the spin state of manganese ions is retained; the electron density increases on the manganese and oxygen atoms of the [Mn6(O)2Piv10] core.
