In the title isonipecotamide salt 2C6H13N2O+·C12H8O6S22−, the 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 dimer interaction [graph set R22(8)], the other giving a similar dimeric interaction but across an inversion centre, both dimers then forming lateral cyclic R42(8) pyrimidinium–amide N—H⋯O interactions. These units are linked both laterally and longitudinally to the sulfonate groups of the dianions through piperidinium N—H⋯O hydrogen bonds, giving a three-dimensional framework structure.

The title compound was synthesized by heating together under reflux for 10 minutes, 2 mmol of 4-carbamoylpiperidine (isonipecotamide) and 1 mmol of biphenyl-4,4'-disulfonic acid in 50 ml of 50% ethanol–water. After concentration to ca 30 ml, partial room temperature evaporation of the hot-filtered solution gave large colourless plates of (I) from which a specimen was cleaved for the X-ray analysis.
Hydrogen atoms involved in hydrogen-bonding interactions were located by difference methods and their positional and isotropic displacement parameters were refined. The H-atoms were included in the
at calculated positions [C–H = 0.93 Å (aromatic) or 0.97 Å (aliphatic)] and with Uiso(H) = 1.2Ueq(C), while using a riding-model approximation.The structures of the β-alanine (Liao et al., 2001) and with 2-(2,4-dinitrobenzyl)pyridine (Smith et al., 2010), but the bis(guanidinium) salt is notable as a co-host structure for cooperative guest recognition in clathrate formation, with numerous aromatic monocyclic and polycyclic hydrocarbons (Swift & Ward, 1998; Swift et al., 1998; Holman & Ward, 2000). The amide 4-carbamoylpiperidine (isonipecotamide, INIPA) is a compound for which there were no structures in the crystallographic literature. We therefore initiated a project aimed at synthesizing a series of salts of INIPA with a number of mainly aromatic, with a view of producing crystalline materials suitable for X-ray structural analysis. This amide has proved to be a particularly useful synthon for this purpose, giving the structures of largely anhydrous 1:1 salts with picric acid, 3,5-dinitrosalicylic acid (two polymorphs) (Smith & Wermuth, 2010a) as well as with the three isomeric mononitrobenzoic acids and 3,5-dinitrobenzoic acid (Smith & Wermuth, 2010b). All of these are 1:1 anhydrous salts while the acetate (Smith & Wermuth, 2010c) is a monohydrate.
salts of biphenyl-4,4'-disulfonic acid (BPDS) are not prevalent in the CSD, e.g. withOur reaction of 4-carbamoylpiperidine with biphenyl-4,4'-disulfonic acid in aqueous ethanol gave good anhydrous crystals of the title compound, (I) and the structure is reported here. With compound (I) (Fig. 1), the
comprises one BPDS dianion (B) which lies across a crystallographic inversion centre and another dianion (A in a general position, together with three INIPA anions (C, D, E). Two of these anions (C and E) give a cyclic dimeric amide–amide interaction [graph set R22(8) (Etter et al., 1990)], the other giving a similar but monomeric interaction across an inversion centre. The two dimers also give a lateral cyclic R24(8) amide-amide interaction (Table 1), these units being linked both laterally and longitudinally to the sulfonate groups of the dianions through piperidinium N—H···O hydrogen bonds, giving a three-dimensional framework structure (Fig 2). One of the amide H-atoms (H41C) has no possible H-bond association.With all three isonipecotamide cations the amide group is rotated ca 100° out of the plane of the benzene ring [comparative torsion angles C3/C5–C4–C41–O41: 107.02 (19)° (C), 108.90 (19)° (D), 100.16 (19)° (E]. In the planar BPDS B dianions there are short intramolecular H2B···H6Bi/H6B···H2Bi contacts (2.07 Å) [for symmetry code (i) see Table 1] similar to those observed in the structure of the 2-(2,4-dinitrobenzyl)pyridinium salt of BPDS (Smith et al., 2010), in which the dianion is also centrosymmetric. The two phenyl rings of the A dianions are non-coplanar [torsion angle C2A–C1A–C11A–C21A, 143.92 (19)°].

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The structures of the Lewis base salts of biphenyl-4,4'-disulfonic acid (BPDS) are not prevalent in the CSD, e.g. with β-alanine (Liao et al., 2001) and with 2-(2,4-dinitrobenzyl)pyridine (Smith et al., 2010), but the bis(guanidinium) salt is notable as a co-host structure for cooperative guest recognition in clathrate formation, with numerous aromatic monocyclic and polycyclic hydrocarbons (Swift & Ward, 1998; Swift et al., 1998; Holman & Ward, 2000). The amide 4-carbamoylpiperidine (isonipecotamide, INIPA) is a compound for which there were no structures in the crystallographic literature. We therefore initiated a project aimed at synthesizing a series of salts of INIPA with a number of carboxylic acids, mainly aromatic, with a view of producing crystalline materials suitable for X-ray structural analysis. This amide has proved to be a particularly useful synthon for this purpose, giving the structures of largely anhydrous 1:1 salts with picric acid, 3,5-dinitrosalicylic acid (two polymorphs) (Smith & Wermuth, 2010a) as well as with the three isomeric mononitrobenzoic acids and 3,5-dinitrobenzoic acid (Smith & Wermuth, 2010b). All of these are 1:1 anhydrous salts while the acetate (Smith & Wermuth, 2010c) is a monohydrate.
Our reaction of 4-carbamoylpiperidine with biphenyl-4,4'-disulfonic acid in aqueous ethanol gave good anhydrous crystals of the title compound, (I) and the structure is reported here. With compound (I) (Fig. 1), the asymmetric unit comprises one BPDS dianion (B) which lies across a crystallographic inversion centre and another dianion (A in a general position, together with three INIPA anions (C, D, E). Two of these anions (C and E) give a cyclic dimeric amide–amide interaction [graph set R22(8) (Etter et al., 1990)], the other giving a similar but monomeric interaction across an inversion centre. The two dimers also give a lateral cyclic R24(8) amide-amide interaction (Table 1), these units being linked both laterally and longitudinally to the sulfonate groups of the dianions through piperidinium N—H···O hydrogen bonds, giving a three-dimensional framework structure (Fig 2). One of the amide H-atoms (H41C) has no possible H-bond association.
With all three isonipecotamide cations the amide group is rotated ca 100° out of the plane of the benzene ring [comparative torsion angles C3/C5–C4–C41–O41: 107.02 (19)° (C), 108.90 (19)° (D), 100.16 (19)° (E]. In the planar BPDS B dianions there are short intramolecular H2B···H6Bi/H6B···H2Bi contacts (2.07 Å) [for symmetry code (i) see Table 1] similar to those observed in the structure of the 2-(2,4-dinitrobenzyl)pyridinium salt of BPDS (Smith et al., 2010), in which the dianion is also centrosymmetric. The two phenyl rings of the A dianions are non-coplanar [torsion angle C2A–C1A–C11A–C21A, 143.92 (19)°].
