Crystal structure of rubidium methyldiazotate

Abstract

The title compound has been crystallized in liquid ammonia as a reaction product of the reductive ammonolysis of the natural compound streptozocin. Elemental rubidium was used as reduction agent as it is soluble in liquid ammonia, forming a blue solution. Reductive bond cleavage in biogenic materials under kinetically controlled conditions offers a new approach to gain access to sustainably produced raw materials.

Palladium(II)-Stabilized Pyridine-2-Diazotates: Synthesis, Structural Characterization, and Cytotoxicity Studies

“…Crystallographically characterized diazotates are rare. ,,− In the crystal, alkali-metal ,, or thallium diazotates exhibit long N–O and short N–N bonds, while for the nitrogen-bound nickel diazotate or recently discovered NHC N 2 O , adducts, the opposite trend is observed (Table ). The nitrogen-bound palladium­(II) diazotates in 1 , 2 , and 7 also exhibit short N–O and long N–N bonds, indicative of a higher contribution of the mesomeric form B (Scheme ).…”
