Highly Coordinated Heteronuclear Calcium–Iron Carbonyl Cation Complexes [CaFe(CO) n ] + ( n =5–12) with d−d Bonding

Interaction 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...

Isolable, gold carbonyl complexes supported by N-heterocyclic carbenes.

Cationic gold carbonyl complexes supported by N-heterocyclic carbene ligands, SIDipp and IDipp, have been synthesized. [(SIDipp)Au(CO)][SbF(6)] has a linear, two-coordinate gold center. [(SIDipp)Au(CO)][SbF(6)] and [(IDipp)Au(CO)][SbF(6)] display ̃ν(CO) values at 2197 and 2193 cm(-1), respectively. Computational studies on [(SIMe)Au(CO)](+) indicate the presence of a strong Au(I)-CO bond.

Solvatochromic 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...
