the melt-phase synthesis of dioctyltin (iv) and triphenyltin (iv) benzoates were carried outusing stoichiometric amounts of benzoic acids and the corresponding organotin (iv) compounds.the reagents were ground together in a mortar and fed into a boiling glass tube. a cannula tubewas inserted into the boiling tube to discharge accumulated gaseous products. a syringe ensureda continuous flow of d...
Each main group element in main group compounds usually takes its own specific coordination number, oxidation number and bonding state. An unusual valence can be achieved by appropriate molecular design and synthetic methods, and such an unusual valence results in characteristic, unique structures and properties. The reactivity of the main group compounds markedly depends on the coordination nu...
The solvent-free melt reactions between lanthanide(iii) nitrates and pyrimidine-4,6-dicarboxylic acid (H2pmdc) led to three-dimensional (3D) coordination polymers with formula [Ln(μ4-pmdc)(NO3)(H2O)]n () [Ln(iii) = La, Ce, Pr, Nd, Sm, and Eu] and {[Ln(μ4-pmdc)(NO3)(H2O)]·H2O}n () [Ln(iii) = Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu]. The crystal structure of compounds is built up from the junction of ...
4(4-nitrophenyl-zao)-2-(2-methoxy phenimino)-phenol and its coordination compounds with ni(ii), cu(ii), co(ii) and fe(iii) have been synthesized and characterized by elemental analyses, ft-ir, far-ir, near ir, uv-vis, mass spectrometry and molar conductivity and their electrochemical behaviours are reported.
