N-[4-(Propyl­sulfamo­yl)phen­yl]acetamide

In the title compound, C₁₁H₁₆N₂O₃S, the S atom has a distorted tetra­hedral geometry [maximum deviation: O—S—O = 119.48 (15)°]. The dihedral angles between the benzene ring and its propyl­sulfonamide and methyl­amide substituents are 71.8 (2) and 5.8 (1)°, respectively. In the crystal, mol­ecules are linked by N_m—H...O_s (m = methyl­amide and s = sulfonamide) hydrogen bonds, forming C(8) chains along the a axis. The two mol­ecule chains are connected by N—H...O hydrogen bonds, generating R₃²(18) rings. The crystal packing is further stabilized by weak inter­molecular C—H...O hydrogen bonds.

N-[(Methyl­sulfan­yl)meth­yl]benzamide

In the title compound, C₉H₁₁NOS, the phenyl ring and formamide unit make a dihedral angle of 23.93 (14)°, whereas the (methyl­sulfan­yl)methyl group is oriented at a dihedral angle of 61.31 (8)° with respect to the phenyl ring. There are inter­molecular N—H...O hydrogen bonds, forming C(4) chains along the [010] direction. These polymeric chains are linked by C—H...O hydrogen bonds to form polymeric sheets in the (110) plane.

2-Chloro­benzohydrazide

The asymmetric unit of the the title compound, C₇H₇ClN₂O, contains two mol­ecules in which the chloro­phenyl and the formic hydrazide units are almost planar (r.m.s. deviations of 0.0081 and 0.0100 Å, respectively, in one mol­ecule and 0.0069 and 0.0150 Å in the other) and are oriented with respect to each other at dihedral angles of 56.8 (2) and 56.9 (2)°. In the crystal, the mol­ecules are consolidated in the form of polymeric chains extending along [010]. R₃³(10) ring motifs exist due to N—H...O and N—H...N hydrogen bonds.

(Acetato-κO)(acetato-κO,O′)bis­(1,3-diazinane-2-thione-κS)cadmium(II)

In the title complex, [Cd(CH₃COO)₂(C₄H₈N₂S)₂], the Cd^II cation is coordinated by three acetate O atoms and two S atoms of Diaz [Diaz = 1,3-diazinane-2-thione = 3,4,5,6-tetra­hydro­pyrimidine-2(1H)-thione]. The Cd^II coordination is augmented by one considerably longer Cd—O bond of 2.782 (3) Å to a carboxyl­ate O atom. The resulting coordination polyhedron around the Cd^II cations can be described as a highly distorted octa­hedron. The Diaz ligand and the acetate anions are linked by N—H...O hydrogen-bonding inter­actions.

Hexa­kis­(μ₃-1-methyl­thio­urea-κ³S:S:S)hexa­kis­[iodidocopper(I)]

The title compound, [Cu₆I₆(C₂H₆N₂S)₆], was obtained from the reaction of copper(I) iodide with N-methyl­thio­urea (Metu) in equimolar amounts in acetonitile. The complex consists of two six-membered trinuclear Cu₃S₃I₃ cores that combine through triply bridging Metu, forming a hexa­nuclear core which has -3 symmetry. The Cu^II atom is coordinated by three S atoms of Metu and one iodide ion in a distorted tetra­hedral geometry. The crystal structure is stabilized by N—H...I hydrogen bonds and cuprophilic inter­actions [Cu...Cu = 3.0264 (9) Å].

rac-(3S,4Z)-3-Chloro-4-[2-(3-fluoro­benzyl­idene)hydrazinyl­idene]-1-methyl-3,4-dihydro-1H-2λ⁶,1-benzothia­zine-2,2-dione

In the title compound, C₁₆H₁₃ClFN₃O₂S, the dihedral angle between the benzene rings is 4.47 (3)°. The conformation of the thia­zine ring is a half-chair and the Cl atom is in an axial orientation. In the crystal, mol­ecules are linked by C—H...F inter­actions, generating C(12) chains propagating in [011]. Aromatic π–π stacking inter­actions [centroid–centroid separations = 3.753 (2) and 3.758 (2) Å] also occur.

2-Eth­oxy-6-{(E)-[(4-methyl­phen­yl)imino]­meth­yl}phenol

The asymmetric unit of the title compound, C₁₆H₁₇NO₂, contains two mol­ecules in which the dihedral angles between the 3-eth­oxy-2-hy­droxy­benzaldehyde and toluidine moieties are 16.87 (8) and 19.93 (6)°. S(6) rings are present in both mol­ecules due to intra­molecular O—H...N hydrogen bonds. In the crystal, one of the mol­ecules is dimerized with an inversion-generated partner, due to two C—H...O inter­actions. This generates an R₂²(8) loop.

2-Fluoro-5-(4-fluoro­phen­yl)pyridine

In the title compound, C₁₁H₇F₂N, the fluoro­benzene and the 2-fluoro­pyridine rings are oriented at a dihedral angle of 37.93 (5)°. In the crystal, only van der Waals inter­actions occur.

In the title compound, C₁₇H₁₇N₃O₂S, the phenyl ring is oriented at dihedral angles of 8.5 (2) and 1.17 (14)°, respectively, to the C=N—N plane and the fused aromatic ring. The thia­zine ring adopts an envelope conformation with the S atom at the flap. In the crystal, a weak C—H...O inter­action connects the mol­ecules, forming a helical chain along the a axis.

2-(4-Bromo­phen­yl)acetohydrazide

In the title compound, C₈H₉BrN₂O, the 1-bromo-4-methyl­benzene group and the formic hydrazide moiety [r.m.s. deviations of 0.0129 and 0.0038 Å] are oriented at a dihedral angle of 80.66 (11)°. In the crystal, mol­ecules are linked via strong N—H...O hydrogen bonds, leading to the formation of chains in the [010] direction. These chains are linked via weaker N—H...N and N—H...O hydrogen bonds, with R₂²(7) and R₃²(7) ring motifs, forming a two-dimensional network parallel to (001).

5-Hy­droxy-2-{(E)-[(3-nitro­phen­yl)iminio]meth­yl}phenolate

The title compound, C₁₃H₁₀N₂O₄, crystallized as the zwitterionic tautomer. As a result, the phenolate C—O⁻ bond [1.296 (2) Å] is shorter than a normal Csp²—O(H) bond, and the azomethine C=N bond [1.314 (2) Å] is longer than a normal C=N double bond. The mol­ecule is nearly planar, the mean plane of the nitro-substituted benzene ring forming dihedral angles of 9.83 (7) and 8.45 (9)° with the other benzene ring and with the nitro group, respectively. The mol­ecular conformation is stabilized by an intra­molecular N—H...O hydrogen bond. In the crystal, strong O—H...O hydrogen bonds link the mol­ecules into double-stranded chains along the b-axis direction. Within the chains there are π–π interactions involving the benzene rings of adjacent molecules [centroid–centroid distance = 3.669 (1) Å]. The chains are linked via C—H...O hydrogen bonds, forming R₂¹(6), R₂¹(7) and R₂²(10) ring motifs.

2-(5-Chloro-1,3-benzothia­zol-2-yl)-4-meth­oxy­phenol

The conformation of the mol­ecule is stabilized by an intra­molecular O—H...N hydrogen bond, forming an S(6) ring motif. In the crystal, mol­ecules are linked into layers parallel to the ac plane by C—H...O hydrogen bonds and π–π stacking inter­actions [centroid–centroid distance = 3.7365 (12) Å].

5-Chloro-2-(3,4,5-trimeth­oxy­phen­yl)-1,3-benzothia­zole

In the title compound, C₁₆H₁₄ClNO₃S, the dihedral angle between the almost-planar benzothia­zole ring system [maximum deviation = 0.012 (3) Å] and the aromatic ring of the trimeth­oxy­phenyl group is 15.56 (6)°. In the crystal, the mol­ecules are arranged into layers parallel to the bc plane, held together only by weak van der Waals forces.
