Diaquabis(1,10-phenanthroline)magnesium dichromate(VI) 1,10-phenanthroline disolvate [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2009
In the title compound, [Mg(C(12)H(8)N(2))(2)(H(2)O)(2)][Cr(2)O(7)]·2C(12)H(8)N(2), the cation and anion are situated on a twofold rotation axis. The Mg(II) ion is coordinated by four N atoms from two 1,10-phenanthroline ligands and two O atoms from coordinated water mol-ecules in a distorted octa-hedral geometry.

Synthesis and Characterization of 1,10-Phenanthroline-mono-N-oxides

open access: yesMolecules, 2021
N-oxides of N-heteroaromatic compounds find widespread applications in various fields of chemistry. Although the strictly planar aromatic structure of 1,10-phenanthroline (phen) is expected to induce unique features of the corresponding N-oxides, so far ...

Crystal Structures of DNA Intercalating Agents Dipyrido[3,2-f:2′,3′-h]quinoxaline (dpq), (Benzo[i]dipyrido[3,2-a:2′,3′c]phenazine (dppn), and [Ir(ppy)2(dppn)][PF6] (Where Hppy = 2-Phenylpyridine)

open access: yesInorganics, 2023
Pyrazino-phenanthroline ligands are commonly used with transition metals as DNA intercalation agents. Herein, we report the characterization of two commonly utilized pyrazino-phenanthroline ligands, dipyrido[3,2-f:2′,3′-h]quinoxaline (dpq) and (benzo[i ...

Phenanthroline‐Catalyzed Stereoretentive Glycosylations [PDF]

open access: yesAngewandte Chemie International Edition, 2019
AbstractCarbohydrates are essential moieties of many bioactive molecules in nature. However, efforts to elucidate their modes of action are often impeded by limitations in synthetic access to well‐defined oligosaccharides. Most of the current methods rely on the design of specialized coupling partners to control selectivity during the formation of ...

2,9-Dichloro-1,10-phenanthroline [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2009
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.
