Guanidinium 3-carboxy-2,3-dihydroxypropanoate monohydrate
In the title hydrated salt, CH(6)N(3) (+)·C(4)H(5)O(6) (-)·H(2)O, the deprotonated carboxyl group is disordered over two positions with a site-occupancy ratio of 0.945 (3):0.055 (3). The bond lengths in the guanidinium cation are inter-mediate between normal C-N and C=N bond lengths, indicating significant delocalization in this species. In the crystal structure, anions and water mol-ecules are...
متن کاملBis[1-(isopropylideneamino)guanidinium] bis(3-nitrobenzoate) monohydrate
The asymmetric unit of the title salt hydrate, 2C(4)H(11)N(4) (+)·2C(7)H(4)NO(4) (-)·H(2)O, comprises two independent 1-(isopropyl-ideneamino)guanidinium cations, two independent 3-nitro-benzoate anions and a water mol-ecule of crystallization. There are minimal geometric differences between the two planar [maximum deviations 0.061 (2) and 0.088 (2) Å] cations, and between the two almost planar...
متن کاملBis(guanidinium) 4,5-dichlorophthalate monohydrate
In the structure of the title hydrated salt, 2CH(6)N(3) (+)·C(8)H(2)Cl(2)O(4) (2-)·H(2)O, the planes of the carboxyl-ate groups of the dianion are rotated out of the plane of the benzene ring [dihedral angles = 48.42 (10) and 55.64 (9)°]. A duplex-sheet structure is formed through guanidinium-carboxyl-ate N-H⋯O, guanidinium-water N-H⋯O and water-carboxyl-ate O-H⋯O hydrogen-bonding associations.
متن کاملGuanidinium 3-nitrobenzoate
The title compound, CH(6)N(3) (+)·C(7)H(4)NO(4) (-), an anhydrous guanidinium salt, shows a N-H⋯O hydrogen-bond network in which the guanidinium cation is involved in three cyclic R(2) (1)(6) hydrogen-bonding associations with separate carboxyl-ate O-atom acceptors. Further peripheral associations include a cyclic R(1) (2)(4) cation-anion inter-action, forming inter-linked undulating sheets in ...
متن کاملCrystal structure of quinolinium 2-carboxy-6-nitrobenzoate monohydrate
In the anion of the title hydrated mol-ecular salt, C9H8N(+)·C8H4NO6 (-)·H2O, the protonated carboxyl and nitro groups makes dihedral angles of 27.56 (5) and 6.86 (8)°, respectively, with the attached benzene ring, whereas the deprotonated carb-oxy group is almost orthogonal to it with a dihedral angle of 80.21 (1)°. In the crystal, the components are linked by O-H⋯O and N-H⋯O hydrogen bonds, g...
