1 Source of materials

In a representative experiment 4-aminobiphenyl (16.9 mg, 0.10 mmol) was dissolved in 10 mL of methanol, then benzenesulfonic acid (15.8 mg, 0.10 mmol) in 2 mL of methanol was added. The solution was stirred for 5 min, then filtered into a test tube and left standing at room temperature. After ca. 12 days colorless block crystals were collected.

2 Experimental details

Hydrogen atoms attached to the C atoms were placed in calculated positions with d(C–H) = 0.93 Å [1]. Positions of the active hydrogen atoms were located from the Fourier difference syntheses [2].

3 Comment

Salts have always been eye-catching aspects of crystal engineering CE that can offer an alternative but efficient approach for improving the physicochemical characteristics of a target compound, such as solubility, bioavailability, hygroscopicity, stability, density, elasticity, plasticity, and melting point [3]. Meanwhile, salts are also known as the paradise of material science for exploring novel phenomena and functionalities of optical [4], room-temperature phosphorescence [5], ferroelectricity [6], etc. Therefore, molecular salts have attracted considerable interest and found their potential application in various fields of pharmaceutical [7], energetic [8], and photovoltaics industries [9, 10].

In the asymmetric unit there existed each of a 4-aminiumbiphenyl and benzenesulfonate (Figure 1), akin to diiso-propyl-ammonium benzene-sulfonate [11] and 2-aminiumbenzoic acid benzene-sulfonate [12].

The benzenesulfonic acid donates its sulfonic H to the NH2 of 4-aminobiphenyl. There is an ion pair with no solvent molecules. The bond lengths and angles within these moieties are in the expected ranges. At 4-aminiumbiphenyl the both phenyl twisted by 27.7° from each other. The C13–C18 plane intersected at 30.5/28.2° with both rings at the cation. In the title crystal structure all of the bond geometries are in the normal range. The S–O lengths are ranging from 1.438(2) to 1.455(2) Å, the S(1)–C(13) (1.774(3) Å) was akin to the filed one [13]. The benzenesulfonate is unambiguously tetrahedral, with three O and a aryl unit: O(3)–S(1)–O(2) (113.11(13)); O(3)–S(1)–O(1) (113.06(13)); O(2)–S(1)–O(1) (110.77(13)); O(3)–S(1)–C(13) (108.01(13)); O(2)–S(1)–C(13) (105.84(13)); and O(1)–S(1)–C(13) (105.45(13)°) are for tetrahedral environment.

One 4-aminiumbiphenyl was anchored to one benzenesulfonate by the N–H⋯O hydrogen bond of 2.775(3) Å from one H of the –NH3+ and one O at the –SO3, and CH–O contact of 3.581 Å from the aryl CH ortho to the –NH3+ and the second O at the –SO3 to make a heteroadduct. The heteroadducts were linked by the N–H⋯O hydrogen bond of 2.781(3)–2.829(3) Å the –NH3+ and the –SO3, N–H⋯S hydrogen bond of 3.644(2) Å with the –SO3 and CH–O contact of 3.233 Å from the aryl CH ortho to the –SO3 and the –SO3 to set up 1D chain in the c-axis. The chains were merged by the N(1)–H(1B)⋯O(1)#2 hydrogen bond and the O⋯O contact of 2.934 Å between the –SO3 to establish 2D sheet in the bc plane. The O⋯O contact was comparable with the document [14]. The sheet enclosed the R12(3), R22(8), R33(9), and R33(10) rings according to Bernstein [15].
