Propane-1,2-diammonium bis(6-carboxypyridine-2-carboxylate) dihydrate
The reaction of propane-1,2-diamine (pn) and pyridine-2,6-dicarboxylic acid (pydcH(2)) in a 1:2 molar ratio in aqueous solution resulted in the formation of the title compound, C(3)H(12)N(2) (2+)·2C(7)H(4)NO(4)·2H(2)O or (pnH(2))(pydcH)(2)·2H(2)O. The structure contains two monoanionic deprotonated forms of pyridine-2,6-dicarboxylic acid molecules (pydcH)(-), a diprotonated propane-1,2-diamine ...
متن کاملBis(propane-1,2-diammonium) benzene-1,2,4,5-tetracarboxylate dihydrate
In the crystal of the title hydrated molecular salt, 2C(3)H(12)N(2) (2+)·C(10)H(2)O(8) (4-)·2H(2)O, the packing is stabilized by extensive N-H⋯O and O-H⋯O hydrogen-bonding inter-actions involving all three species, forming a supra-molecular three-dimensional structure. The tetraanion is generated by inversion.
متن کاملPropane-1,3-diammonium dichromate(VI)
The title compound, (C(3)H(12)N(2))[Cr(2)O(7)], consists of a discrete dichromate anion with an eclipsed conformation and a propane-1,3-diammonium cation. Both kinds of ions have a mirror plane passing through the bridging O atom and the central methyl-ene C atom of the Cr(2)O(7) (2-) and C(3)H(12)N(2) (2+) moieties, respectively. Anions and cations are alternately stacked to form columns paral...
متن کاملDiammonium tricadmium tris(sulfate) dihydroxide dihydrate
The title compound, (NH(4))(2)Cd(3)(SO(4))(3)(OH)(2)(H(2)O)(2), has been obtained serendipitously. It is isotypic with the heavier alkali analogues M(2)Cd(3)(SO(4))(3)(OH)(2)(H(2)O)(2) (M = K, Rb, Cs). The structure contains two Cd(2+) ions, one in a general position and one with site symmetry m. The former Cd(2+) ion is coordinated by three O atoms of three SO(4) groups, two hydroxide O atoms ...
متن کاملDiacetatobis(propane-1,3-diamine)nickel(II) dihydrate
In the title complex, [Ni(CH(3)COO)(2)(C(3)H(10)N(2))(2)]·2H(2)O, the Ni(II) atom resides on a centre of symmetry and is in an octa-hedral coordination environment comprising four amino N atoms and two carboxyl-ate O atoms. Inter-molecular N-H⋯O and O-H⋯O hydrogen bonds produce R(2) (1)(6), R(2) (2)(12), R(3) (2)(8) and R(5) (5)(16) rings, which generate a two-dimensional polymeric network para...
