The constituents of the title 12H14N4O2S·C7H6O2, are connected by an eight-membered hetero-synthon {⋯NCNH⋯OCOH}, whereby the carboxylic acid forms donor and acceptor hydrogen bonds with a pyrimidine N atom and the adjacent amine, respectively. The dimeric aggregates thus formed are arranged in rows with their terminal NH2 groups forming N—H⋯O hydrogen bonds with neighbouring aggregates to form a two-dimensional array in the ac plane with an overall T-shaped topology. Layers interdigitate along the b axis being connected by C—H⋯O, C—H⋯π and π–π [centroid–centroid distance = 3.6316 (19) Å] interactions.

Colourless crystals of (I) were isolated from the 1/1 co-crystallization of 4-amino-N-(4,6-dimethylpyrimidin-2-yl)benzene-1- sulfonamide (ACROS, 0.11 mmol) and benzoic acid (ACROS, 0.11 mmol) in acetone; m. pt. 481–493 K.
C-bound H-atoms were placed in calculated positions (C–H 0.95–0.98 Å) and were included in the
in the riding model approximation with Uiso(H) set to 1.2–1.5Ueq(C). The N– and O-bound H-atoms were located in a difference Fourier map and were refined with distance restraints of O–H = 0.84±0.01 Å and N—H = 0.88±0.01 Å, and with Uiso(H) = xUeq(carrier atom), where x = 1.5 for O and x = 1.2 for N.In continuation of co-crystallization experiments of molecules related to pharmaceuticals (Broker & Tiekink, 2007; Ellis et al., 2009; Arman et al., 2010), the title
containing a 1:1 ratio of 4-amino-N-(4,6-dimethylpyrimidin-2-yl)benzene-1-sulfonamide and benzoic acid was isolated, (I). Co-crystals of the sulfonamide with various substituted benzoic acid derivatives have been investigated previously (Caira, 1991; Caira, 1992).A single molecule of each component comprises the
of (I), Fig. 1. These are connected into dimeric aggregates by an eight membered hetero-synthon {···NCNH···OCOH} involving the O3-carboxylic acid-H donating to the pyrimidine-N4 and the carbonyl-O4 accepting a hydrogen bond from the adjacent N2-amine-H. Such synthons are common to related co-crystals (Caira, 1991; Caira, 1992).In the crystal packing, the benzoic acid and pyrimidine residues lie parallel to the ac plane and are arranged in a row along the a axis as highlighted in Fig. 2. The sulfonamide-N1-amine-H atoms bridge successive dimeric aggregates of an adjacent row. This occurs by the formation of hydrogen bonds to the carbonyl-O3 of one dimeric aggregate and a second N–H···O interaction involving the sulfonamide-O1 atom of another. This establishes a two-dimensional array, Fig. 3, that has an overall T-shaped topology. As shown in Fig. 4, the global crystal packing comprises the inter-digitation of successive rows of T-shaped and inverted T-shaped molecules. The interactions between the inter-digitated residues are of the type C—H···O and C—H···π, Table 1, and π–π [Cg(N3,N4,C7—C10)···Cg(C13—C18) = 3.6316 (19) Å for i: 1/2 + x, 11/2 - y, 1 - z].

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'s involving l.s. planes. |
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. |

In continuation of co-crystallization experiments of molecules related to pharmaceuticals (Broker & Tiekink, 2007; Ellis et al., 2009; Arman et al., 2010), the title co-crystal containing a 1:1 ratio of 4-amino-N-(4,6-dimethylpyrimidin-2-yl)benzene-1-sulfonamide and benzoic acid was isolated, (I). Co-crystals of the sulfonamide with various substituted benzoic acid derivatives have been investigated previously (Caira, 1991; Caira, 1992).
A single molecule of each component comprises the asymmetric unit of (I), Fig. 1. These are connected into dimeric aggregates by an eight membered hetero-synthon {···NCNH···OCOH} involving the O3-carboxylic acid-H donating to the pyrimidine-N4 and the carbonyl-O4 accepting a hydrogen bond from the adjacent N2-amine-H. Such synthons are common to related co-crystals (Caira, 1991; Caira, 1992).
In the crystal packing, the benzoic acid and pyrimidine residues lie parallel to the ac plane and are arranged in a row along the a axis as highlighted in Fig. 2. The sulfonamide-N1-amine-H atoms bridge successive dimeric aggregates of an adjacent row. This occurs by the formation of hydrogen bonds to the carbonyl-O3 of one dimeric aggregate and a second N–H···O interaction involving the sulfonamide-O1 atom of another. This establishes a two-dimensional array, Fig. 3, that has an overall T-shaped topology. As shown in Fig. 4, the global crystal packing comprises the inter-digitation of successive rows of T-shaped and inverted T-shaped molecules. The interactions between the inter-digitated residues are of the type C—H···O and C—H···π, Table 1, and π–π [Cg(N3,N4,C7—C10)···Cg(C13—C18) = 3.6316 (19) Å for i: 1/2 + x, 11/2 - y, 1 - z].
