“…These studies are essentially a continuation of those previously reported by us on other sulfur-containing groups attached to germanium, such as dithiophosphates1-3 and (V,iV-dialkyldithiocarbamates.4"6 -Alkyl dithiocarbonates (xanthates) have been extensively used as ligands, particularly toward transition metals. 7,8 Studies of main-group element xanthates include structural studies on tin(II) and tin(IV) derivatives. In Sn(S2COEt)4, two of the ligands are monodentate and two are bidentate,9 whereas only monodentate ligands are found for bis(0-ethyl xanthato)bis-(quinolin-8-olato)tin(IV)10 and bis(0-methyl dithiocarbonato)tin(II).…”

“…Most of them correspond to four-and five-coordinate systems and just a few to six-coordinate complexes. For the three hits with six-coordination, the l-Ala ligands are modified to obtain three or tetradentate chelates (Ng et al, 2006;Krajewski et al, 1984;Comba et al, 1991). When inspecting in detail the four-coordinate systems (15 structures), in most of them it is observed a fifth Cu-L bond in the apical axis.…”

Metalloproteins involved in oxidation–reduction processes in metabolism are fundamental for the wellbeing of every organism. The use of amino-acid-based compounds as ligands for the construction of biomimetic coordination systems represents a promising alternative for the development of new catalysts. Herein is presented a new family of copper, zinc and nickel coordination compounds, which show four-, five- and six- coordination geometries, synthesized using Schiff base ligands obtained from the amino acids L-alanine and L-phenylalanine. Structural analysis and property studies were performed using single-crystal X-ray diffraction data, spectroscopic and electrochemical experiments and DFT calculations. The analysis of the molecular and supramolecular architectures showed that the non-covalent interactions developed in the systems, together with the identity of the metal and the amino acid backbone, are determinants for the formation of the complexes and the stabilization of the resultant geometries. The CuII complexes were tested as candidates for the electrochemical conversion reduction of nitrite to NO, finding that the five-coordinate L-phenylalanine complex is the most suitable. Finally, some insights into the rational design of ligands for the construction of biomimetic complexes are suggested.

“…[3] Moreover, selective coordination of particular cations depends on the dimension of the macrocyclic ring (type, number, and position of complexing heteroatoms, and so on) and the stereochemistry imposed by the arms. In previous works, it has been shown that the diaza [18]crown-6 ether is a versatile receptor that is able to adapt to the coordination preferences of the particular metal cation, [4][5][6][7][8][9] whereas the diaza [15]crown-5 ether has been revealed to be a receptor that imposes seven-coordination around the metal ion. [8,[10][11][12][13][14] The size of chelate rings formed upon coordination of the pendant arms to the metal ion influences the nuclearity of the complexes.…”

crown-6 ligand were determined by means of X-ray crystallography. The Ni II complex is centrosymmetric; the geometry around the metal ion is slightly distorted octahedral whereby the equatorial sites were occupied by four N atoms, and the axial positions by two O atoms that come from the crown moiety. For the Zn IIdiaza[18]crown-6 complex, an irregular octahedral coordination was observed whereby the metal ion is asymmetrically placed in the macrocyclic cavity. The equatorial plane is occupied by two N and two O atoms of the crown moiety, and two N atoms of the triazolyl motifs on the pendant arms occupy the axial positions. The diamagnetic character of the Zn II ion allows its structural study in solution by NMR spectroscopy. A dynamic behavior was observed at room tem-
