New approaches to the selective synthesis of the [2-B10H9I]− anion have been reported based on careful control of the reaction medium acidity. The mechanism of the iodination was proposed and the regioselectivity of electrophilic substitution of the [B10H10]2− anion was explained based on B3LYP-calculations of the potential energy surface of the system using the mixed basis 6-31G∗/LanL2DZ. The obtained...
4-Amino-2,1,3-benzothiadiazole (L) and its model complexes with Cu+, Zn2+, Ag+ and Cd2+ have been computationally investigated in order to reveal the origins of coordination preferences of this multidentate ligand. The computational description is consistent with the analysis of experimental crystal structures of the coordination compounds described earlier and of two new complexes viz. [ZnL(H2O)Cl...
New silver complexes [AgL(NO3)]n (1), [AgL2(NO3)]n (2) and [AgL3(NO3)]2 (3) (L = 4-amino-2,1,3-benzothiadiazole) were obtained as single-phase products of the reactions of AgNO3 with L by varying their ratio. The structures of 1–3 were established by single-crystal X-ray diffraction and contain {Ag2L2} units, where L acts as a bridging ligand. The other metal coordination sites are occupied by O atoms...
