متن کاملVII. Workshop Powder Diffraction Structure Determination and Refinement from Powder Diffraction Data
New techniques have been integrated into EXPO (Altomare et al., 1999), a package devoted to extracting the integrated intensities from an indexed powder diffraction pattern and to solving crystal structures via Direct Methods. An efficient peak-search algorithm and an improved version of the program TREOR90 (Werner et al., 1985) have been introduced in order to offer new tools for a more powerf...
متن کاملAlaptide from synchrotron powder diffraction data
THE TITLE COMPOUND [SYSTEMATIC NAME: (8S)-8-methyl-6,9-diaza-spiro-[4.5]decane-7,10-dione], C(9)H(14)N(2)O(2), consists of two connected rings, viz. a piperazine-2,5-dione (DKP) ring and a five-membered ring. The DKP ring adopts a slight boat conformation and the bonded methyl group is in an equatorial position. The five-membered ring is in an envelope conformation. In the crystal structure, in...
متن کاملPimobendan B from powder diffraction data
The title mol-ecule, C19H18N4O2 {systematic name: (RS)-6-[2-(4-meth-oxy-phen-yl)-1H-benzimidazol-5-yl]-5-methyl-4,5-di-hydro-pyridazin-3(2H)-one}, adopts an extended conformation. The dihedral angles between the central benzimidazole ring sytem and the pendant meth-oxy-phenyl and pyridazinone residues are 1.41 (18) and 9.7 (3)°, respectively. In the crystal, N-H⋯N hydrogen bonds link the imadaz...
