The title compound, C14H13ClN2O2S, crystallized in the enanti-omorphic defining hexa-gonal space group P61 [Flack parameter = -0.02 (7)]. The partially hydrated form of the same compound, crystallizing in the triclinic space group P-1, has been reported previously [Kia et al. (2009b). Acta Cryst. E65, o1119], as has the crystal structure of the bromo derivative, also crystallizing in the space ...
With only a 2.6 Å resolution laboratory powder diffraction pattern of the θ phase of Pigment Yellow 181 (P.Y. 181) available, crystal-structure solution and Rietveld refinement proved challenging; especially when the crystal structure was shown to be a triclinic dimethylsulfoxide N-methyl-2-pyrrolidone (1:1:1) solvate. The crystal structure, which in principle has 28 possible degrees of freedom...
The title compound, C9H9N3O2S, is a monoclinic (C2/c) polymorph of the previously reported triclinic structure [Kang (2013 ▶). Acta Cryst. E69, o1327]. The mol-ecule is almost planar with an r.m.s. deviation of 0.069 Å from the mean plane of all non-H atoms. The benzoyl and terminal thio-urea fragments adopt a transoid conformation with respect to the central carbonyl O atom. Two intra-molecula...
In the crystal structure of the title compound, C₁₆H₁₄F₃N₃OS·C₃H₈O, the mol-ecules are linked into chains along [010] via N-H⋯O and O-H⋯N hydrogen bonds. The triclinic form was reported by Ren et al. [(2011). Acta Cryst. E67, o270] and the first monoclinic form by Chen et al. [(2012). Acta Cryst. E68, o2015-o2016]. The fused five-and six-membered rings make a dihedral angle of 1.22 (2)°, while ...
---------------------------------------------------------------------***--------------------------------------------------------------------Abstract Tbe doped Calcium alumino silicate (CaAl2Si2O8) phosphor was synthesized by combustion method at initiating temperature of 7000C, using urea as a reducer. XRD, Thermoluminescences, absorption spectra, FTIR and Thermoluminescences spectra were recor...
The crystal structure of the title compound, C(15)H(17)NO(2), contains two nearly identical but crystallographically independent molecules, each with a double bond connecting an azabicyclic ring system to a 3-methoxybenzylidene moiety. The space group is triclinic P-1. The benzene ring is twisted by 18.44 (5) and 22.35 (4) degrees with respect to the plane of the double bond connected to the az...
The title mol-ecule, C(39)H(28)N(2)O, is a well known dendron used in the synthesis of phenyl-azomethine dendrimers. The central benzophenone core is twisted, as expected, due to hindrance between H atoms: the dihedral angle between core benzene rings is 54.49 (5)°, identical to that of the stable polymorph of benzophenone (56°). For the same reason, phenyl groups substituting imine C atoms mak...
The title compound, C(16)H(14)F(3)N(3)OS·H(2)O, which had been previously characterized in the space group P-1 [Ren et al. (2011 ▶). Acta Cryst. E67, o270], has now been crystallized from 1-propanol in the monoclinic form in the space group P2(1)/c. While the triclinic form is a Z' = 2 crystal, the new monoclinic polymorph includes one main mol-ecule and one water lattice mol-ecule in the asymm...
A donor-acceptor compound based on N,N,N',N'-tetramethyl-p-phenylene-diamine and 1,2,4,5-tetracyanobenzene (TMPD:TCNB) has been synthesized. The crystal structure of the black 1:1 complex formed between TMPD and TCNB has been determined by single crystal X-ray diffraction at room temperature. The compound crystallizes in the triclinic space group P-1 with cell dimensions: a = 7.4986(15) å, b =7...
X-ray diffraction analysis reveals the thiogermanic acid H(4)Ge(4)S(10) possesses discrete adamantane-like Ge(4)S(10)(4)(-) complex anions. Each thioanion is composed of four corner shared GeS(2.5)(-) tetrahedral units. Crystals were grown from anhydrous liquid hydrogen sulfide reactions with glassy germanium sulfide at room temperature. The crystal structure was solved and refined from single ...
