Crystal Structure of(E )-1,2-Bis(1,1-dimethyl-2-oxopropyl)diaz-1-ene-1,2-diium-1,2-diolate, the trans -Dimer of3-Methyl-3-nitrosobutan-2-one

Abstract

The solid state structure of(E )-1,2-bis(1,1-dimethyl-2-oxopropyl)diaz-1-ene-1,2-diium-1,2-diolate, (3a), the trans -dimer of3-methyl-3-nitrosobutan-2-one, has been determined by X-raycrystallographic analysis; subsequent comparison of the observedgeometrical parameters for 3a with the literature values foreleven other trans or (E )-dimers suggests thatthere is no correlation between the N—N distances in thesedimers and their respective rates of dissociation to monomer insolution.
