Aromatic Metal Clusters

Synthesis and Structural Characterization of Lithium and Iron Complexes Containing a Chelating Phenolate Phosphane Ligand

“…The diethyl ether solution was filtered through a pad of celite and the solvents evaporated to dryness under reduced pressure to give the product as a brown solid; yield 35 mg (80 %). 1 …”

“…The pentane solution was then filtered through a pad of Celite and the solvents evaporated to dryness under reduced pressure to give the product as an off-white solid; yield 85 mg (95 %). 1 2 (200 mg, 0.27 mmol) was added to a THF solution (1 mL) of FeCl 2 (34 mg, 0.27 mmol) at -35°C. The reaction solution was stirred at room temperature overnight and the solvents evaporated to dryness under reduced pressure.…”

“…Unusual physical properties and/or chemical transformations may evolve significantly. [1][2][3][4][5][6][7][8] For instance, lithium phenolate aggregates have been used as building blocks in the controlled assembly of metal-organic frameworks. [9] We are currently exploring the reaction and structural chemistry with metal complexes of hybrid chelating ligands.…”

Structures and aromaticity of the planar B2XY (X=N, P and Y=O, S, Se) and Al2MN (M=C, Si, Ge and N=S, Se) clusters

“…Despite the fact that various dispute has been getting along with the development of this concept, certainly, we must admit that aromaticity has been playing an important role in interpreting molecular properties for many compounds [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. The substantial energy stabilization, bond length equalization, unusual reactivity, and characteristic spectroscopic features as well as distinctive magnetic properties are some important aspects with which researchers depict this special concept.…”

Geometries, stability and aromaticity of , [M(Al2P2)]− (M=Li, Na, K, Cu) and N(Al2P2) (N=Be, Mg, Ca, Zn) clusters

“…Especially, when this concept was successfully extended from traditional organic molecules into various clusters, the research of aromaticity attract much interest again. In recent years, small Al or P-based clusters become a rich area of research in cluster physics and chemistry [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40]. Z. Chen, et al reported that Al 4À 4 was claimed to be antiaromatic, but aromaticity exists in Al 4 Li À 3 on the basis of theoretical analysis [41].…”
