Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 89-86-1, Name is 2,4-Dihydroxybenzoic acid, molecular formula is , belongs to phthalazine compound. In a document, author is Milenkovic, Milica, Quality Control of 2,4-Dihydroxybenzoic acid.
A square-pyramidal Ni(II) complex (1) with the composition [NiL(HL’)]CIO4 center dot H2O was synthesized in the reaction of nickel(II) perchlorate and 2[2-(diphenylphosphino)benzylidene]-1-phthalazinylhydrazone (HL). The coordination surrounding the Ni(II) ion consist of a PNN coordinated deprotonated HL ligand and its corresponding oxidation product phosphine oxide HL’ coordinated via two nitrogen atoms of the hydrazinophthalazine moiety. The structure of Ni(II) complex 1 was determined by X-ray analysis, IR spectroscopy, elemental analysis and magnetic measurements. In the reaction of copper(II) perchlorate with HL, a binuclear phthalazine bridged Cu(I) complex (2) was obtained with the composition [Cu-2(HL)(2)](ClO4)(2)center dot C2H5OH. The structure of Cu(I) complex 2 was determined by X-ray analysis, IR and NMR spectroscopy, elethental analysis and magnetic measurements. (C) 2016 Elsevier Ltd. All rights reserved.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 89-86-1, in my other articles.
