Neutral pentacoordinate silicon complexes with SiO2FC skeleton: Synthesis, structural characterization and stereodynamical behavior

Mixed-ligand complexes of Zn(II), Cd(II) and Cu(II) with triethanolamine and p-nitrobenzoic acid: Syntheses and crystal structures

“…Two ligand coordination is reached by bonding the nitrogen and two hydroxyl oxygen atoms to the metal atom, with the third oxygen atom remaining uncoordinated [8,9]. In the case of the one TEA ligand complex, all four electron pair donating atoms participate in coordination bond formation with the central atom, while two positions in the internal sphere are occupied by water molecules [3].…”

“…anticancer, antibacterial, anti-inflammatory, fungicidal activity, stimulating effects in animal production and seed germination effects [9][10][11][12]. Cu [13][14][15] and Cd [16,17] complexes of TEA have been obtained and structurally characterized by X-ray crystallography.…”

Oligosilanylated Silocanes

“…In contrast to silatranes, the noncoordinating exo -form of silocanes is favored in most cases over the endo -form ( Scheme 1 ) [ 3 , 4 , 14 , 15 ]. The reasons for this can be either steric (f.i., no structurally characterized N-Ph silocanes [ 16 , 17 , 18 , 19 , 20 ] with pronounced N→Si interaction are known, whereas a fair number of exo N-Me silocanes [ 6 , 20 , 21 , 22 , 23 , 24 ] are known) or electronic (at least one additional electronegative substituent seems to be required on the silocane Si to exhibit enough electrophilicity for a stable N→Si interaction).…”
