An insensitive explosive, cis-1,4-Dinitroglycoluril also known as DINGU, is considered to investigate the compatibility of it and its nitramine isomers with zinc in 1:1 composites. The model composites of them have been subjected to density functional treatment at the level of B3LYP/6-31++G(d,p). Within the restrictions of the theory and the level of calculations performed, it has been found that two of the model composites considered are unstable and undergo N-NO2 bond rupture. Only the third one, in which N-NO2 bonds exist in different rings but nearby of each other is stable. Some physical and molecular orbital properties of the systems are obtained and discussed.
