Bis(tert-butylammonium) oxalate
2006
The component species in the title compound, 2C4H12N2+·C2O42−, interact by way of N—H⋯O hydrogen bonds, resulting in a layered network. N and two C atoms of the cation possess site symmetry m and the C atom of the anion has site symmetry 2.
Ethyldimethylammonium oxalate
2006
The title crystal structure, C4H12N+·C2HO4−, contains discrete ethyldimethylammonium cations and oxalate monoanions. Linear chains of oxalate monoanions are formed by strong O—H⋯O hydrogen bonds. These chains are further connected by N—H⋯O and C—H⋯O hydrogen bonds through ethyldimethylammonium cations, forming channels along the a axis.
Crystal structure of bis-(allyl-ammonium) oxalate.
2014
The title salt, 2C3H8N+·C2O42−, crystallized with six independent allylammonium cations and three independent oxalate dianions in the asymmetric unit. One of the oxalate dianions is nearly planar [dihedral angle between CO2planes = 1.91 (19)°], while the other two are twisted with angles of 11.3 (3) and 26.09 (13)°. One cation has a synperiplanar (cis) conformation with an N—C—C—C torsion angle of 0.9 (3)°, whereas the five remaining cations are characterized bygauchearrangements, with the N—C—C—C torsion angles ranging from 115.9 (12) to 128.8 (3)°. One of the allylammonium cations is positionally disordered (fixed occupancy ratio = 0.45:0.55). In the crystal, the cations and anions are co…
