Structures of Energetic Acetylene Derivatives HC≡CCH₂ONO₂, (NO₂)₃CCH₂C≡CCH₂C(NO₂)₃ and Trinitroethane, (NO₂)₃CCH₃

Abstract

The molecular structures and relative ratios of the two conformers (anti and gauche) of HCCCH 2 ONO 2 detected in the gas phase at room temperature have been determined by electron diffraction. The results are discussed on the basis of quantum chemical calculations. The molecular structures of (NO 2 ) 3 CCH 2 C≡CCH 2 C(NO 2 ) 3 and (NO 2 ) 3 CCH 3 have been determined by X-ray diffraction. A 109 Ag NMR study was performed for silver trinitromethanide Ag[C(NO 2 ) 3 ] in various polar solvents.

Tetranitromethane: A Nightmare of Molecular Flexibility in the Gaseous and Solid States

“…Very early investigations of the structure of TNM argued with its reactivity, which mimicks that of [C(NO 2 ) 3 ] − NO 2 + , and with the high stability and pseudohalogenic nature of the trinitromethanide anion. This view was confirmed by the existence of a variety of salts of the corresponding strong acid HC(NO 2 ) 3 , including K[C(NO 2 ) 3 ], Ag[C(NO 2 ) 3 ], pseudointerhalogen compounds such as NCC(NO 2 ) 3 and N 3 C(NO 2 ) 3 , the well‐studied halogenotrinitromethanes XC(NO 2 ) 3 (X=F, Cl, Br, I), and trinitroethane …”
