The title compound, CH(7)N(4) (+)·C(4)H(5)O(4) (-), is a molecular salt containing discrete amino-guanidinium and succinate ions. The amino-guanidinium cation is nearly planar, with a maximum deviation of 0.035 (1) Å. The dihedral angle between the amino-guanidinium cation and the succinate anion is 3.35 (6)°. The crystal packing exhibits inter-molecular N-H⋯O and O-H⋯·O hydrogen bonds.
The mixed-valence FeFe 2D coordination polymer formulated as [TAG][FeFe(ClCNAn)]·(solvate) 1 (TAG = tris(amino)-guanidinium, ClCNAn = chlorocyanoanilate dianionic ligand) crystallized in the polar trigonal space group P3. In the solid-state structure, determined both at 150 and at 10 K, anionic 2D honeycomb layers [FeFe(ClCNAn)] establish in the ab plane, with an intralayer metal-metal distance of 7.860 Å, alternating with cationic layers of TAG.
In energetic materials, the crystal density is an important parameter that affects the performance of the material. When making ionic energetic materials, the choice of counter-ion can have detrimental or beneficial effects on the packing, and therefore the density, of the resulting energetic crystal. Presented herein are a series of five ionic energetic crystals, all containing the dianion 5,5'-(3,3'-bi[1,2,4-oxa-diazole]-5,5'-di-yl)bis-(1-tetra-zol-1-olate), with the following cations: hydrazinium () (2NH·CNO), hydroxyl-ammonium () 2NHO·CNO [Pagoria (2017).

The possibility of controlling the compression extent and the coiling shape of the 1,12-diammoniumdodecane guest is shown by changing the dimensions of the internal space of the host guanidinium 1,3,5,8 pyrene-tetrasulfonate PTS(4-) crystalline capsules by using guanidinium (G(+)), amino-guanidinium (AG(+)), and diaminoguanidinium (A2G(+)) cations.
The title compound, CH(7)N(4) (+)·C(4)H(3)O(4) (-), is a molecular salt in which the amino-guanidinium cations and fumarate monoanions are close to planar, with maximum deviations of 0.011 (1) and 0.177 (1) Å, respectively.
The title compound, CH(7)N(4) (+)·C(4)H(5)O(4) (-), is a molecular salt containing discrete amino-guanidinium and succinate ions. The amino-guanidinium cation is nearly planar, with a maximum deviation of 0.035 (1) Å.
