Achillea tenuifolia Lam. (Asteraceae) afforded a dichloromethane fraction from which three known compounds β-sitosterol (compound1), 5-hydroxy, 4',6,7– trimethoxy flavone (salvigenin compound 2), and methyl-gallate (compound 3) were isolated for the first time. The structure of isolated compounds was elucidated by different spectroscopic methods. Applying the molar-ratio method, the complexat...

the nitrite ® nitro isomerization in nitritopentaamine cobalt (iii) halides has been known. in this paper, the effect of the size of the counter ions (noncoordinated groups) on the rate of isomerization in nitritopentaamine cobalt (iii) halides, is reported. the rate of isomerization is decreased by increasing the size of the counter ions. this decrease is explained on the basis of steric inter...

The Complexes of Ti(iii), V(iii), Mn(iii), Co(iii), Ru(iii), Ru(ii), MoO(v), Fe(iii), MoO 2 (vi) and UO 2 (vi) with S-benzyl-β-N-(2-hydroxy-5-bromophenyl) methylendithiocarbazate have been synthesized and characterised by melting points, molar conductance,magnetic susceptibility, electronic and IR spectral studies. The complexes of Ti(iii), V(iii), Mn(iii), Ru(iii) & MoO(v) are paramagnetic whi...
