4-Amino-N-(4,6-dimethyl-pyrimidin-2-yl)benzene-sulfonamide-benzoic acid (1/1).

ABSTRACT: The constituents of the title co-crystal, C(12)H(14)N(4)O(2)S·C(7)H(6)O(2), are connected by an eight-membered hetero-synthon {?NCNH?OCOH}, whereby the carb-oxy-lic 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 NH(2) 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 inter-digitate along the b axis being connected by C-H?O, C-H?? and ?-? [centroid-centroid distance = 3.6316?(19)?Å] inter-actions.

The constituents of the title co-crystal, C(12)H(14)N(4)O(2)S·C(7)H(6)O(2), are connected by an eight-membered hetero-synthon {⋯NCNH⋯OCOH}, whereby the carb-oxy-lic 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 NH(2) 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 topolog ...[more]

Project description:In the asymmetric unit of the title co-crystal, C(7)H(5)NO(4)·C(12)H(14)N(4)O(2)S, there are two independent but conformationally similar heterodimers, which are formed through inter-molecular N-H?O(carb-oxy) and carbox-yl-pyrimidine O-H?N hydrogen-bond pairs, giving a cyclic motif [graph set R(2) (2)(8)]. The dihedral angles between the rings in the sulfonamide molecules are 78.77?(8) and 82.33?(9)° while the dihedral angles between the ring and the CO(2)H group in the acids are 2.19?(9) and 7.02?(10)°. A two-dimensional structure parallel to the ab plane is generated from the heterodimer units through hydrogen-bonding associations between NH(2) and sulfone groups. Between neighbouring two-dimensional arrays there are two types of aromatic ?-? stacking inter-actions involving either one of the pyrimidine rings and a 4-nitro-benzoic acid mol-ecule [minimum ring centroid separation = 3.5886?(9)?Å] or two acid mol-ecules [minimum ring centroid separation = 3.7236?(10)?Å].

4-Amino-N-(4,6-dimethyl-pyrimidin-2-yl)benzene-sulfonamide-2-nitro-benzoic acid (1/1).

Project description:In the asymmetric unit of the title co-crystal, C(12)H(14)N(4)O(2)S·C(7)H(5)NO(4), the sulfamethazine and 2-nitro-benzoic acid mol-ecules form a heterodimer through inter-molecular amide-carb-oxy-lic acid N-H?O and carb-oxy-lic acid-pyrimidine O-H?N hydrogen-bond pairs, giving a cyclic motif [graph set R(2) (2)(8)]. The dihedral angle between the two aromatic ring systems in the sulfamethazine mol-ecule is 88.96?(18)° and the nitro group of the acid is 50% rotationally disordered. Secondary aniline N-H?O(sulfone) hydrogen-bonding associations give a two-dimensional structure lying parallel to the ab plane.

4-(5-Chloro-2-hydroxy-benzyl-idene-amino)-N-(4,6-dimethyl-pyrimidin-2-yl)benzene-sulfonamide.

Project description:The title compound, C(19)H(17)ClN(4)O(3)S, is a Schiff base compound of 5-chloro-salicylaldehyde and sulfamethazine [4-amino-N-(4,6-dimethyl-2-pyrimidin-yl)benzene-sulfonamide]. The geometry around the S atom is distorted tetra-hedral, comprising two O atoms of the sulfonyl group, a C atom of a benzene ring and the amino N atom. The title compound has an intra-molecular O-H⋯N hydrogen bond and two inter-molecular C-H⋯O and N-H⋯O hydrogen bonds, which link neighbouring mol-ecules into 10-membered rings. As a result of an unavoidable conformational arrangement, a slightly short intra-molecular contact of distance 2.59 Å exists between an O atom of the sulfonyl group and an H atom of the sulfamethazine benzene ring.

N-(4,6-Dimethyl-pyrimidin-2-yl)-4-(oxolan-2-ylamino)benzene-sulfonamide.

Project description:The title compound, C(16)H(20)N(4)O(3)S, adopts an l-shaped conformation, as seen by the dihedral angle of 76.93 (7)° formed between the two aromatic rings. The most notable feature of the crystal packing is the formation of N-H⋯O and N-H⋯N hydrogen bonds that lead to supra-molecular chains orientated along the b axis.

4-[(5-Bromo-2-hydroxy-benzyl-idene)amino]-N-(4,6-dimethyl-pyrimidin-2-yl)benzene-sulfonamide-4-bromo-2-[(E)-({4-[(4,6-dimethyl-pyrimidin-2-yl)sulfamo-yl]phen-yl}iminio)meth-yl]phenolate [0.61 (7)/0.39 (7)].

Project description:The title compound, 0.61C(19)H(17)BrN(4)O(3)S·0.39C(19)H(17)BrN(4)O(3)S, is a Schiff base derived from 5-bromo-salicylaldehyde and 4-amino-N-(4,6-dimethyl-2-pyrimidin-yl)benzene-sulfonamide(sulfamethazine) and is isostructural with its chloro analogue. The geometry of the title mol-ecule points to the enol (OH-C=C-C=N) form as the major tautomer, however two electron-density maxima corresponding to the H atoms of the OH and NH groups, found in the region of a strong intra-molecular N⋯H⋯O hydrogen bond, do not allow the elimination of the presence of the zwitterionic (O(-)-C=C-C=NH(+)) form in the crystal. Refinement of the occupancies of these H atoms gave a 0.61 (7):0.39 (7) ratio of the enolic and zwitterionic forms. The two benzene rings within the mol-ecule are nearly coplanar and the central benzene ring forms a dihedral angle of 84.1 (1)° with the pyrimidine fragment. An inter-molecular N-H⋯O hydrogen bond links mol-ecules into chains extended along the a axis and a C-H⋯O link is also present. The H atoms of one of the methyl groups are disordered over two sites with an occupancy ratio of 0.72 (7):0.28 (7).

Bis[2-((4,6-dimethyl-pyrimidin-2-yl){2-[(4,6-dimethyl-pyrimidin-2-yl)sulfan-yl]eth-yl}amino)-eth-yl] disulfide.

Project description:Bis[2-(4,6-dimethyl-pyrimidin-2-ylsulfan-yl)eth-yl]amine under hydro-thermal conditions has unexpectedly been transformed into the title compound, C(32)H(44)N(10)S(4). In the title mol-ecule, the zigzag 3,10-diaza-6,7-disulfanyldodecyl skeleton has two dimethyl-pyrimidinylsulfanyl groups at both ends, and the aza atoms each carry a dimethyl-pyrimidinyl unit. The N atoms in the skeleton show a planar coordination.

4-Amino-N-(6-chloro-5-methoxy-pyrimidin-4-yl)benzene-sulfonamide.

Project description:In the title compound, C(11)H(11)ClN(4)O(3)S, the S atom is bonded in a distorted tetra-hedral geometry, by two O atoms, a C atom of the benzene ring and an amino N atom. The essentially planar pyrimidine ring [maximum deviation = 0.020?(1)?Å] forms a dihedral angle of 87.57?(5)° with the benzene ring. In the crystal structure, pairs of mol-ecules are linked by inter-molecular N-H?O hydrogen bonds to generate centrosymmetric R(2) (2)(8) ring motifs. In addition, mol-ecules are linked into a three-dimensional extended network by inter-molecular N-H?N, N-H?O and C-H?O hydrogen bonds.

2-Amino-4,6-dimethyl-pyrimidin-1-ium 2,3,5-triiodo-benzoate 2,3,5-triiodo-benzoic acid monosolvate.

Project description:In the crystal structure of the title compound, C(6)H(10)N(3) (+)·C(7)H(2)I(3)O(2) (-)·C(7)H(3)I(3)O(2), two R(2) (2)(8) motifs are observed. One is generated by the inter-action of the 2-amino-4,6-dimethyl-pyrimidin-1-ium cation with the carboxyl-ate group of the 2,3,5-triiodo-benzoate anion via N-H?O hydrogen bonds. The other R(2) (2)(8) motif is formed by the inter-action of two centrosymmentrically related pyrimidine moieties through N-H?N hydrogen bonds. The two motifs combine to form a linear heterotetra-meric unit. Heterotetra-meric units are linked by a carbox-yl-carboxyl-ate O-H?O hydrogen bond (involving the O-H group of neutral 2,3,5-triiodo-benzoic acid and an O atom of the anion), forming a supra-molecular chain along the a axis. In addition, components are held by weak I?O interactions in the range 3.023?(5) to 3.382?(5)?Å and I?I inter-actions in the range 3.6327?(7) to 4.0025?(8)?Å.

2-{4-[Acet-yl(eth-yl)amino]-benzene-sulfonamido}-benzoic acid.

Project description:In the title compound, C(17)H(18)N(2)O(5)S, the dihedral angle between the aromatic rings is 68.59?(10)° and the C-S-N-C torsion angle is -81.84?(18)°. The mol-ecular conformation is stabilized by an intra-molecular N-H?O hydrogen bond, generating an S(6) ring. In the crystal, mol-ecules are linked by C-H?O and O-H?O hydrogen bonds into a three-dimensional network.

2-Amino-4,6-dimethyl-pyrimidin-1-ium chloride.

Project description:In the title compound, C6H10N3(+)·Cl(-), the cation is essentially planar with an r.m.s. deviations of the fitted atoms of 0.008 Å. In the crystal, adjacent ions are linked by weak N-H⋯Cl hydrogen bonds involving the pyrimidine and amine N atoms, forming a three-dimensional network. C-H⋯π inter-actions between the methyl and pyrimidine groups and π-π stacking [centroid-centroid distance = 3.474 (1) Å] between parallel pyrimidine ring systems are also observed.
