PREPARATION AND CHARACTERIZATION OF [Ni (MAP) ] ; H- MAP = 2- (METHYLAMINO) PYRIDINE H. Aghabozorg* and H. H. Monfared
We have recently synthesized [Ni (MAP) ] complex [H-MAP= 2- (methylamino) pyridine]. 2- (Methy1amino)pyridine reacts with MeLi in THF and generates the lithium salt (Li-MAP). Further reaction of NiCl with two equivalent of this ligand in THF leads to the formation of a dark red solution. Analytical data, molecular weight, and magnetic susceptibility of this complex confirm the formula [N...
متن کاملIn Vitro Flower Production in Some Species of Hyoscyamus (H. pusillus L., H. arachnoideus Pojark, and H. niger L.)
Various plant organ segments including segments from roots (root tip, and root collar), stems, leaves, and also seeds of several Hyoscyamus species (i.e. H. pusillus, H. arachnoideus, annual and biennial H. niger from two distinct geographical regions) were cultured on MS media with various growth regulator combinations, to assess the ability of flower production. Statistical assessments showed...
متن کاملLEWIS-BASE ADDUCTS OF LEAD (11) COMPLEXES. CRYSTAL STRUCTURES OF Pb (BIPY) (H O) (N0 ) AND Pb (PHEN) (H 0) (NO )
Reactions of equemolar amounts of lead (II) nitrate and 2,2'- bipyridine o r l , 10- phenanthroline in aqueous methanolicsolution yield crystals of Pb (bipy)(H O)(NO ) (1) or Pb (phen) (H O) (NO ) (2) respectively. Their structures were determined by X-ray crystallography. The method and structure determination is described
متن کاملTwo Dimensional H ^ H and ^C^H-Correlation NMR: The Analysis of ?/3-Allylnickel Complexes
Simple ?/3-allyl-?/5-cyclopentadienylnickel complexes can be obtained as pure compounds whereas their alkyl substituted analogues are obtained as a mixture of syn/anti isomers [1], The individual complexes cannot be further separated using standard purification techniques. In a previous communication we showed that the NMR spectra of such a mixture of isomers can be analysed with the help of in...
