In the title compound, C(15)H(13)ClO(3)S, the chloro-thio-phene and dimeth-oxy-phenyl groups are linked by a prop-2-en-1-one group. The C=C double bond exhibits an E conformation. The mol-ecule is non-planar, with a dihedral angle of 31.12 (5)° between the chloro-thio-phene and dimeth-oxy-phenyl rings. The meth-oxy group at position 3 is coplanar with the(More)
In the title mol-ecule, C(16)H(15)ClO(4)S, the chloro-thio-phene and trimeth-oxy-phenyl rings make a dihedral angle of 31.12 (5)°. The C=C double bond exhibits an E conformation. In the crystal, C-H⋯O inter-actions generate bifurcated bonds, linking the mol-ecules into chains along the b axis.
Boric oxide based quaternary glasses in the system PbF2-TeO2-B2O3-Eu2O3 have been prepared by melt quenching technique. Density, molar volume, FTIR, UV-Vis techniques were used to probe the structural modifications with incorporation of europium ions in the glass network. An increase in glass density & decrease in molar volume (Vm) values proved the(More)
A chalcone derivative, 1-(5-bromothiophen-2-yl)-3-(2,3-dimethoxyphenyl)prop-2-en-1one (BTDMP), has been synthesized and grown as a high-quality single crystal by the slow evaporation solution growth technique. The compound was characterized by FT-IR and NMR studies. The crystal has been subjected to single-crystal x-ray diffraction studies and cell(More)
