Hydrazine-1,2-diium bis(3-carboxy-4-hydroxybenzenesulfonate) tetrahydrate
Reaction of 5-sulfosalicylic acid with hydrazine hydrate at pH = 1 results in the formation of the title hydrated salt, 0.5N(2)H(6) (2+)·C(7)H(5)O(6)S(-)·2H(2)O. The hydrazinium dications lie on centres of inversion. They are located between 3-carb-oxy-4-hy-droxy-benzene-sulfonate anions, forming inter-molecular N-H⋯O hydrogen bonds with sulfonate ions and water mol-ecules of crystallisation. F...

In the title compound, [Ca(C(13)H(10)N(4)O(8))(H(2)O)(3)]·4H(2)O, the Ca(II) ion is hepta-coordinated by two N atoms and two O atoms from a tetra-dentate 1,3-bis-(1H-imidazole-4,5-dicarb-oxy-l-ate) propane dianion and three water O atoms, giving a distorted penta-gonal-bipyramidal coordination environment. The Ca-O bond lengths are in the range 2.354 (3)-2.453 (2) Å, while the Ca-N bond lengths...
متن کامل1,2-Bis(4-nitrobenzoyl)hydrazine
The title mol-ecule, C(14)H(10)N(4)O(6), crystallizes with one half-mol-ecule in the asymmetric unit; the mid-point of the N-N bond lies on an inversion centre. The nitro and amide groups are twisted with respect to the benzene ring, making dihedral angles of 14.6 (5) and 31.1 (5)°, respectively. In the crystal structure, mol-ecules are linked through N-H⋯O hydrogen bonding between the imino an...
متن کامل1-Diphenylmethyl-4-ethylpiperazine-1,4-diium dichloride
In the title compound, C(19)H(26)N(2) (2+)·2Cl(-), the piperazinediium ring exhibits a chair conformation. The dihedral angle between the two benzene ring planes is 76.45 (13)°. Both amine-group H atoms participate in hydrogen bonding with the two Cl atoms.

The title complex, [Nd(C(6)H(6)NO(3)S)(2)(C(12)H(8)N(2))(2)(H(2)O)(3)]NO(3)·4H(2)O, comprises a mononuclear cation, an NO(3) (-) anion and two uncoordinated water mol-ecules; the Nd(III) cation, one coordinated water mol-ecule, and the NO(3) (-) anion each lie on a twofold axis of symmetry. The Nd(III) ion exhibits an NdN(4)O(5) coordination environment comprising two O atoms of two monodentate...
