Abstract Synthesis of nickel(II) complex with N,N′-bis(2′-pyridine) methyl-1,10-phenanthroline-2,9-dimethanamine and report on the crystal structure of the complex.

Synthesis and structure of Mn(II) and Zn(II) complexes containing 1,10-phenanthroline unit

Abstract The Mn(II) and Zn(II) complexes of N,N′-diisopropyl-1,10-phenanthroline-2,9-dimethanamine have been synthesised, and the structure of the two complexes have been studied by X-ray crystallography.

Synthesis and crystal structures of copper and manganese complexes withN,N′-dibenzyl-1,10-phenanthroline-2,9-dimethylamine

The new ligand, N,N′-dibenzyl-1,10-phenanthroline-2,9-dimethylamine trihydrochloric acid monohydrate (L · 3HCl·H2O), has been synthesized and characterized. Complexes of the ligand (L) with CuII and MnII were prepared and their crystal structures were determined. The copper ion is five-coordinated via three nitrogen atoms of the ligand and two chloride ions, while the manganese ion is six-coordinated by three nitrogens of the ligand, two chloride ions and one water molecule. In both complexes, the ligand behaves in a tri-dentate fashion and the uncoordinated nitrogen of the other arm is protonated.

Synthesis of novel 1,10-phenanthroline-2,9-bis-α-amino acid conjugates

Starting from 2,9-dimethyl-1,10-phenanthroline, the syntheses of eight novel 1,10-phenanthroline-2,9-bis-α-aminoacid conjugates (α-amino acids: DL-Ala, L-Val, L-Phe, L-His, L-Ile, L-Met, L-Glu, L-Asp) are described in detail.

Syntheses of the novel thiamacrocycles containing the 1,10-phenanthroline unit

The syntheses of three new thiamacrocycles 5, 6 and 7 including the 1,10-phenanthroline unit are described and show high selectivity for Pb2+ and Ag+.
