In the mononuclear title complex, [Ni(C(12)H(8)N(2)O)(2)(H(2)O)(2)](NO(3))(2), the Ni(II) ion is coordinated in a distorted octa-hedral geometry. The dihedral angle between the two mean planes defined by the phenanthroline ligands is 88.26 (6)°. Intra- and intermolecular O-H⋯O hydrogen bonds between the cation and the anions lead to the formation of a layered arrangement parallel to (010).

Ethylene glycol dinitrate (EGDN) is a nitrate ester explosive widely used in military ordnance and missile systems. This study investigates the decomposition dynamics of the EGDN cation using a comprehensive approach that combines femtosecond time-resolved mass spectrometry (FTRMS) experiments with electronic structure and molecular dynamics computations. We identify three distinct dissociation time scales for the metastable EGDN cation of approximately 40-60 fs, 340-450 fs, and >2 ps.

In the binuclear title complex, [La(CHO)(CHN)(HO)](NO)·0.5HO, the two lanthanum ions are nine coordinate in a distorted trigonal-prismatic geometry. Each La ion is bonded to three N atoms of the Schiff base, 1-(pyridin-2-yl)-2-(pyridin-2-yl-methyl-ene)hydrazine and is coordinated by one acetate group, which acts in -bidentate mode and two acetate groups that act in -mode between the two La ions.

Adverse drug reactions (ADRs) in elderly patients are frequently attributed to age-related altered pharmacokinetics and the complexities of polypharmacy to manage multiple chronic conditions, making elderly patients more susceptible to ADRs. The following is a case report of an 80-year-old female patient with systemic symptoms of chest pain, low blood sugar, mouth ulcers, and concentrates on peripheral edema due to nitrate vasodilator isosorbide mononitrate (ISMN). She had hypertension, diabetes, ischemic heart disease, and chronic obstructive pulmonary disease (COPD).

Monensic acid is a natural polyether ionophore and is a therapeutic of first choice in veterinary medicine for the control of coccidiosis. Although known as a sodium-binding ligand, it can also form a variety of coordination species depending on experimental conditions applied. In this study, we present the crystal structures and properties of Co(II) and Mn(II) complexes of sodium monensinate (MonNa) derived from the reaction of MonNa with cobalt or manganese dinitrates.

Background: Diabetic animals often display dysregulated nitric oxide (NO) metabolism, contributing to vascular dysfunction. This study evaluates the metabolic and vascular effects of organic nitrate isosorbide mononitrate (ISMN) versus inorganic sodium nitrate (NaNO3) in mice with type 1 diabetes mellitus (T1DM) induced by streptozotocin (STZ).
Experimental Approach: T1DM was induced in male C57Bl6 mice with STZ ip and confirmed by fasting glucose.
