In this investigation, CuInS2 ternary compound was synthesized by injection of thiourea solution into a hot copper-indium solution. The CuCl, InCl3 along with (SC (NH2)2) were used as a precursor dissolved in high boiling point solvent such as oleylamine (CH(CH2)17NH2) and oleic acid (CH(CH2)16COO...
in this thesis, phosphorus ylides [phbppy], [no2bppy] and [brbppy] have been synthesized through the formation of phosphonium salt and dihydrogenation, followed by the reaction of pd(oac)2 and the orthopalladated dinuclear complexes [pd(?-cl)(phbppy)]2, [pd(?-cl)(no2bppy)]2 and [pd(?-cl)(brbppy)]2 have been produced. the reaction of dinuclear complexes and bidentate ligands [l = bipy (2,2-bipyr...
Previous work has indicated that PEP mutase catalyzes the rearrangement of phosphoenolpyruvate to phosphonopyruvate by a dissociative mechanism. The crystal structure of the mutase with Mg(II) and sulfopyruvate (a phosphonopyruvate analogue) bound showed that the substrate is anchored to the active site by the Mg(II), and shielded from solvent by a large loop (residues 115-133). Here, the cryst...
The slightly yellow-coloured title complex, [Zn(C18H16N4O4)(H2O)] n , crystallizes with one mol-ecule in the asymmetric unit. The structure clearly shows the mer-η(4) O,O,N,N-binding mode of the N,N'-bis-(2-cyano-ethyl-propeno-yl)-1,2-di-amido-benzene ligand stabilizing the Zn centre of a distorted octa-hedral environment. The fifth coordination site in one apical position is held by a coordina...
In the crystal structure of the title compound, [Co(NCS)2(C6H8N2)2(H2O)2]·C6H8N2, the Co(II) cation is coordinated by the N atoms of two terminal thio-cyanate anions, the O atoms of two water mol-ecules and two N atoms of two 2,6-di-methyl-pyrazine ligands. The coordination sphere of the resulting discrete complex is that of a slightly distorted octa-hedron. The asymmetric unit comprises a Co(I...
