Crystal Structures and Characterization of Copper(II) Complexes of N,N,N'N'-Tetrakis(2-pyridylmethyl)-1,2-ethanediamine
The structure of [Cu(tpen)](ClO4)2 (tpen = N,N,N',N'-tetrakis(2-pyridylmethyl)-1,2-ethanediamine) has been identified by X-ray crystallography. The copper(II) ion is surrounded by two amine N atoms and three pyridine N atoms of the ligand, making a distorted trigonal-bipyramid. Among the six potential N donor atoms (two amine N and four pyridine N atoms), only one pyridine N atom remains uncoor...
متن کاملSolvatochromic Properties of Heteroleptic Copper(II) Complexes Containing N,N,N',N'-Tetramethylethylenediamine and 2-Aacetylcyclopentanone Ligands
Three new heteroleptic copper(II) complexes, [(tmen)Cu(dike)H2O]X where tmen = N,N,N',N'-tetramethylethylenediamine, dike = 2-acetylcyclopentanone anion and X= ClO4- (1), Cl- (2) and Br- (3) are prepared and characterized by elemental analyses, molar conductance measurements and IR and UV-Vis spectroscopy techniques. The complex 1 is fairly soluble in various organic solvents and demonstrates d...
متن کاملInteraction of alanine with lithium. I- the alanine–Li -n (H20) n (0–2) complexes
The energy minima of systems made of an alanine molecule, a lithium cation and a various number of watermolecules have been determined with the help of quantum mechanical computations at the B3LYP DensityFunctional Theory level of computation and the standard 6-311++G (d,p) basis set. Several structures, close inenergy are found and the presence of one or two water molecules around the cation m...
متن کاملRedetermination of Crystal Structure of N,N'-bis (2-Hydroxybenzylidene)-2,2-Dimethyl-1,3-Propanediamine
The structure of N,N'-bis(2-hydroxybenzylidene)-2,2-dimethyl-1,3-propanediamine, C19H22N2O2, has been studied at low temperature (120K) by means of single-crystal X-ray diffraction. Solving the structure shows an orthorhombic unit cell, with P212121 space group, Z = 4, a = 6.1046 (4) Å, b = 15.8349 (11)</e...
متن کاملATTEMPTED PREPARATION OF N-SUBSTITUTED DIPHENYLCYCLOPROPENEIMINE N-OXIDE
The reaction of diphenylcyclopropenone with several N-substituted hydroxylamine and primary amines are investigated. Most of these reactions led to ring opened or ring enlarged products, instead of the desired N-Oxide or imine. The reaction of cyclopropeneimine with peracid-another possible route to N-substituted cyclopropeneimine N-Oxide is studied. Most of the unexpected products are ide...
