Ethyl 6-(6-methoxy-2-naphthyl)-2-oxo-4-(2-thienyl)cyclohex-3-ene-1-carboxylate
Autor: Hongqi Li, Anil N. Mayekar, B. Narayana, H. S. Yathirajan, W. T. A. Harrison
Publikováno v: Acta Crystallographica Section E, Vol 65, Iss 7, Pp o1533-o1533 (2009)
The title compound, C24H22O4S, was prepared by reaction between (2E)-3-(6-methoxy-2-naphthyl)-1-(2-thienyl)prop-2-en-1-one and ethyl acetoacetate. In the crystal, the cyclohexenone ring shows a distorted half-chair conformation. The length of the dou

Na3/4(NH4)1/4ZnPO4, a new framework zincophosphate. Survey of MZnPO4 tetrahedral topologies
Autor: W. T. A. Harrison
Publikováno v: Zeitschrift für Kristallographie - Crystalline Materials. 215:288-292
The synthesis and single crystal structure of Na3/4(NH4)1/4ZnPO4, a new sodium-ammonium zinc phosphate, are reported. This phase adopts a previously unseen tetrahedral topology and is built up from a three-dimensional network of ZnO4 [dav(Zn-O) = 1.9

An extreme case of ZnO6octahedral distortion in trizinc tris(selenite) hydrate, Zn3(SeO3)3
Autor: W. T. A. Harrison
Publikováno v: Acta Crystallographica Section C Crystal Structure Communications. 55:1980-1983
Trizinc tris[trioxoselenate(IV)] hydrate, Zn 3 (SeO 3 ) 3 .H 2 O, is built up from ZnO 6 octahedra [d av (Zn-O) = 2.127 (2) A] and SeO 3 pyramids [d av (Se-O) = 1.693 (2) A], sharing vertices and edges. One of the zinc octahedra is exceptionally dist

Thallium titanium phosphate, Tl3Ti3O(PO4)3(P2O7)
Autor: W. T. A. Harrison
Publikováno v: Acta Crystallographica Section C Crystal Structure Communications. 55:1200-1203
The title compound, trithallium trititanium oxide tris-(phosphate) diphosphate, consists of a three-dimensional network of vertex-sharing TiO 6 , PO 4 and P 2 O 7 groups [d av (Ti-O) = 1.940 (3) and d av (P-O) = 1.536 (4) A]. Extra-framework Tl + cat

High-pressure crystal chemistry and phase transition of RbTi2(PO4)3
Autor: Galen D. Stucky, Robert M. Hazen, Larry W. Finger, T E Gier, D C Palmer, W T A Harrison
Publikováno v: Journal of Physics: Condensed Matter. 6:1333-1344
Unit-cell parameters of RbTi2(PO4)3, a framework structure (space group R3c) with alternating corner-linked Ti octahedra and P tetrahedra that define six-coordinated alkali cation sites, were determined at eight pressures from 0.0 to 6.2 GPa, and cry
