Full quantum chemical calculations with density functional theory (DFT) show that bond-strengthening back-donation to a π-diborene, recently discovered for transition metal systems (Braunschweig and co-workers, Nat. Chem., 2013, 5, 115–121), would be just as favored for Main Group silylene complexes.

Diaminodinitroethylene (DADNE) has three constitutional isomers, geminal, cis and trans. The geminal one is the well known FOX-7 explosive. It is a push-pull type molecule. In the present study, within the restrictions of density functional theory at the level of B3LYP/6-311++G(d,p), two cyclic dimeric structures of DADNE are investigated quantum chemically. Also their mono ionic forms have been investigated (unrestricted treatment). All the structures are found to be stable. Various quantum chemical and spectral data are collected computationally and discussed.

This article describes the synthesis and tautomerism of 2- (4,6-dioxo-1,3,5-triazinan-2-ylidene) hydrazinecarboxyamide. The synthesized compound was investigated using elemental analysis methods, and quantum chemical calculations performed in ChemCraft 1.8 and Gaussian programs. Composite methods of the Gaussian family (G4) and density functional theory (DFT) methods (BLYP / 6-311 + G (d, p)) were used. The data obtained indicate that the BLYP / 6-311 + G (d, p) well suited for describing such systems in order to save 66 machine resources. Based on the calculated resistance series, it was established that the main form is diketoenolform.
