Diammonium biphenyl-4,4′-disulfonate
In the title salt, 2NH(4) (+)·C(12)H(8)O(6)S(2) (2-), the dianion has crystallographic inversion symmetry. A three-dimensional framework is formed from primary hydrogen-bonded sheet structures comprising ammonium N-H⋯O(sulfonate) inter-actions and is linked peripherally through the biphenyl residues of the anions. This open framework has 43 Å(3) solvent-accessible voids.

In the crystal structure of the title salt, C(2)H(10)N(2) (2+)·C(10)H(6)O(6)S(2) (2-), both the cation and anion lie on special positions of site symmetry. These are linked by N-H⋯O and N-H⋯(O,O) hydrogen bonds, forming a layer structure.
متن کاملBis(4-carbamoylpiperidinium) biphenyl-4,4′-disulfonate
In the title isonipecotamide salt 2C(6)H(13)N(2)O(+)·C(12)H(8)O(6)S(2) (2-), the asymmetric unit comprises one biphenyl-4,4'-disulfonate dianion which lies across a crystallographic inversion centre and another in a general position [dihedral angle between the two phenyl rings is 37.1 (1)°], together with three isonipecotamide cations. Two of these cations give a cyclic homomeric amide-amide di...
متن کاملBis[2-(2,4-dinitrobenzyl)pyridinium] biphenyl-4,4′-disulfonate trihydrate
In the structure of the title salt, 2C(12)H(10)N(3)O(4) (+)·C(12)H(8)O(6)S(2) (2-)·3H(2)O, determined at 173 K, the biphenyl-4,4'-disulfonate dianions lie across crystallographic inversion centres with the sulfonate groups inter-acting head-to-head through centrosymmetric cyclic bis-(water)-bridged hydrogen-bonding associations [graph set R(4) (4)(11)], forming chains. The 2-(2,4-dinitro-benz-y...
متن کاملtrans-Tetraaquabis(nicotinamide-κN)cadmium(II) biphenyl-4,4′-disulfonate
In the title compound, [Cd(C(6)H(6)N(2)O)(2)(H(2)O)(4)](C(10)H(8)O(6)S(2)), the Cd(II) ion is located on a crystallographic inversion centre. An octa-hedral coordination geometry is defined by four water mol-ecules in one plane, and two trans N-atom donors of the nicotinamide ligands. The biphenyl-4,4'-disulfonate anion also lies on a crystallographic inversion centre. In the crystal structure,...
