چکیده
The title mol-ecule, C(12)H(6)Cl(2)N(2), is almost planar (the r.m.s. deviation of C atoms is 0.04 Å). The C-N and C-C distances indicate delocalization of the π-electrons in the aromatic fused-ring system.

Dibromido(2,9-dimethyl-1,10-phenanthroline-κ2 N,N′)zinc
The reaction of equimolar amounts of zinc bromide and 2,9-dimethyl-1,10-phenanthroline in dry methanol provided the title compound, [ZnBr(2)(C(14)H(12)N(2))], in good yield. The Zn(II) ion is coordinated in a distorted tetra-hedral environment by two N atoms from the chelating 2,9-dimethyl-1,10-phenanthroline ligand and two bromide ions. There is inter-molecular π-π stacking between adjacent ph...

In the title polymer, [Cd(C(2)N(3))(2)(C(16)H(16)N(2)O(2))](n), the Cd(II) ion is coordinated by two N atoms from one 2,9-dieth-oxy-1,10-phenanthroline mol-ecule and four N atoms from four symmetry-related dicyanamide ions in a distorted octa-hedral geometry. In the 2,9-dieth-oxy-1,10-phenanthroline ligand, the O and C atoms of the eth-oxy groups are located almost in the plane defined by the p...

In the title compound, [CuCl(2)(C(14)H(12)N(2))], the complex molecule has m symmetry, with the mirror plane oriented parallel to the planar molecule and the ligated Cu(II) atom. The metal centre has a distorted tetra-hedral coordination formed by two N atoms from one 2,9-dimethyl-1,10-phenanthroline ligand and two Cl atoms. There is inter-molecular π-π stacking between adjacent 2,9-dimethyl-1,...
متن کاملActinide selectivity of 1,10-phenanthroline-2,9-dicarboxamide and its derivatives: a theoretical prediction followed by experimental validation.
The conventional concept of selective complexation of actinides with soft donor ligands (either S or N donor) has been modified here through exploiting the concept, "intra-ligand synergism", where a hard donor atom, such as oxygen preferentially binds to trivalent actinides [An(iii)] as compared to the valence iso-electronic trivalent lanthanides [Ln(iii)] in presence of another soft donor cent...
متن کاملSelective separation of trivalent f-ions using 1,10-phenanthroline-2,9-dicarboxamide ligands in ionic liquids.
1,10-Phenanthroline-2,9-dicarboxamide complexants decorated with alkyl chains and imidazolium cations have been studied for extraction of trivalent f-ions into imidazolium ionic liquids. The dicationic complexants are shown to extract Am over Eu with separation factors >50 and high extraction efficiencies. The different size selectivities for lanthanide ions were observed for these two types of...
