Crystal structure of 4-[benzylideneamino]-3-thiophen-2-yl-methyl-4,5-dihydro-1H-[1,2,4]triazole-5-one
(MAIK NAUKA/INTERPERIODICA/SPRINGER, 2013)
The crystal structure of the title compound C14H12N4OS was determined by the X-ray diffraction method. The compound crystallizes in the triclinic space group with Z = 2. The molecule is not planar: the dihedral angle between ...
EFFECTS OF LEAF AND PLANT AGE ON SPECIFIC LEAF AREA IN DECIDUOUS TREE SPECIES QUERCUS CERRIS L. VAR. CERRIS
(BANGLADESH BOTANICAL SOC, 2013)
In Quercus cerris L. var. cerris, four diameters at breast height (BDH) groups were selected as a surrogate for approximate plant age groups to study the effects of plant and leaf age on leaf dry mass, leaf area and specific ...
INFLUENCE OF ACTIVATOR ON MEIOSIS OF TOMATO (LYCOPERSICON ESCULENTUM MILL.)
(BANGLADESH BOTANICAL SOC, 2013)
The cytogenetic effects of activator Act-2 (based in compounds of addition hydro soluble of K-vitamin group a new and specific organic metabolic activator) on meiosis of tomato (Lycopersicon esculentum Mill.) were studied. ...
An experimental and theoretical study on concomitant polymorphism of a dithiocarbonimidates derivate in a single space group
(ELSEVIER SCIENCE BV, 2013)
The title organic dithiocarbonimidates derivate crystallizes in two different polymorphic modifications. The conformational differences between the two crystalline modifications lead to differences in crystal packing and ...
