title: Bis(beta-alaninium) biphenyl-4,4'-disulfonate.
abstract: In the crystal structure of the title compound, 2C(3)H(8)NO(2)(+).C(12)H(8)O(6)S(2)(2-), N-H...O hydrogen bonds formed between the amino H atoms and the sulfonate O atoms give rise to the assembly of cationic beta-alaninium dimers and centrosymmetric biphenyl-4,4'-disulfonate anions into an extended two-dimensional layer. The resulting hydrogen-bonded ribbons can be described as C(2)(2)(6)R(4)(4)(12) according to graph-set notation. C-H...O hydrogen bonds between adjacent sheets further extend the structure into a three-dimensional arrangement.
